Description

A kind of dental prosthetic method

Technical field

The present invention relates to a kind of dental prosthetic method.

Background technology

The current exemplary embodiment that will describe is a kind of method about Dental Erosion.Repair in the direct oral cavity that the method has found to be specially adapted to non-titanio abutment assembly, and will hereafter can described in detail.

Middle medullary substance (dental pulp) in people's tooth is called as Dentinal calcification material by one deck and wraps up, and this medullary substance is connected with nerve with tremulous pulse, vein.Tooth body stretches out from alveolus or teeth groove, and alveolus can be subject to the suppression of jawbone (upper jaw) or mandible (lower jaw) alveolar bone.The part tooth of actual coincidence alveolus is according to certain growth that puts in order.The part (being called as " corona ") that tooth stretches out has fine and close smooth surface, and covered by the connective tissue of one deck calcification, i.e. enamel.Gingiva or gingiva tissue have wrapped up the base portion of corona and between the adjacent surface stretching out tooth, and can support rightly to fix to tooth.

Loss of tooth may cause due to various disease, as dental caries, dental defect, pulpitis, physical injury, gingival and periodontal disease.Periodontal disease is that As time goes on it can hardening calcification by claiming to become caused by the thick antibacterial of one deck of dental plaque.Slight inflammation is symptom that is red and swollen and gingival hemorrhage as gingivitis may have, and this may be developed to other supportive structures and comprise alveolar bone, and then can worsen the more late stage for periodontal, i.e. periodontitis.Gingiva generation atrophy or from tooth limit depart from, cause defining cell body between tooth and gingiva.Along with the deterioration of disease, tooth can become loosening, usually must implement to pull out.Therefore, periodontal disease is the main cause causing loss of tooth.

There is many known methods for designing to be now used for implanting and protection dental case.The most general implantation type is that bone is implanted into formula, and implant is by the jawbone of first surgical installation patient Yu in the method.This implant is the model of root structures, and it can stretch into gingiva to support the abutment filled, and then obtains a dental case.Common abutment is a profile is cylindrical structure, and it enters implant for feature with spiral, and corona can be mounted to the top of this abutment simultaneously.Usually, the conventional method of veteran odontologist enforcement dental implant reparation comprises following 12 steps: (1) takes away sealing cap; (2) readiness tray, tests impression tray simultaneously, delimitates to cut and open forms, the duplicate impression extended (being called as " opening quotation technology ") to allow; (3) the common die that will copy is placed thereon, and tightens; (4) impression material is injected ready pallet; (5) die is pressed into the top of duplicate impression, and waits for until ready; (6) die copied is unclamped; (7) wax is injected part of windowing, around the extension of duplicate impression; (8) impression tray investing duplicate impression is peeled off; (9) connect implant cast and duplicate impression, and dental laboratory will be sent into upper-part; (10) Laboratory Technician will build material and prepare stone matter model, will be returned to odontologist afterwards; (11) odontologist select he or she think optimal stone matter model, again deliver to laboratory, then (12) this Laboratory Technician adjusts abutment, again may deliver to odontologist to be afterwards used for carrying out examination in the oral cavity of patient and to wear, then the requirement based on doctor adjusts abutment again, installs the top of corona to abutment additional simultaneously.

The United States Patent (USP) 4,975,059 of Sendax discloses a kind of pouring type implant abutment.As shown in Figure 1, pouring type implant abutment 10 is that a kind of more excellent acrylic plastics waters building body.This abutment 10 has 12 bottom external screw threads, and they accurately can screw in each screw buckle (in figure not display) of a cylindrical apatite coating implant.The abutment 10 of this acrylic acid material may be that mechanism or model are built.The external dimensions of abutment 10 accords with the external dimensions of attempted supporting implant type.The groove system 14 that the top of abutment 10 has a reticule to portray, engraves groove on the surface 16 of this system, can allow to be rotated down abutment 10 like this and enter implant (not shown) in patient's jawbone.This has incorporated about bone structure and the primary work after removing covering of performing the operation at implant.Now, this abutment 10 can screw in correct position very like a cork, and the lubricant simultaneously adding trace can not make acrylic acid material damaged to ensure to unscrew easily.Afterwards, cut away and have a certain degree to be formed surface 18, thus make this surface reach rapport with the implant of jawbone in other oral cavities or abutment, also make corresponding (rightabout) jawbone keep coordinating simultaneously.The place adjusting or relocate the key being guarantee abutment and its overall comfort level again of such abutment 10 angle.Require that described in 1, this plastic material implanted abutment 10 will be used in building of metal (and being final) abutment, and the abutment of this metal material has the ability keeping with female implant mating as at Sendax.

Clearly, remain a provisional abutment at United States Patent (USP) 4,975,075 abutment 10 of Sendax, just as with the mid-range loading model (die body) of the final or permanent abutment of after-stage.This abutment 10 will be sent to a use for laboratory in the final or permanent abutment of making.Disclosed by Sendax, before this structure is placed into oral cavity and screws in suitable position, the final making of customization abutment can complete molding in indirect experiment room, builds, complete and polishing operate outside.(Lines 65-68, Column 2), after Dental Erosion completes, provisional abutment 10 will be dropped, and can replace with final or permanent abutment simultaneously, this customization abutment can in patient oral cavity several years in service life or many decades.

There is some unfavorable factor in known Oral Repair program, the program of the method is very complicated, and this causes the permeability that Dental Implant is very low.The operation that the present all rounded dentist less than 5% has the ability to implement dental implant is replaced, and all rounded dentist less than 10% in fact carries out plantation repair due to the complexity of current techniques.Repair the permeability of industry to increase dental implant, odontologist needs the repair procedure and the technology that use simplification, and they should be flat-footed, high performance-price ratios, and also comprises extremely low access of being in hospital.Emphasize it is also necessary to following responsibility, namely in order to a soft tissue model suitably in planned implant region is implemented to shift accurately, most abutment system uses closed or open pallet impression technique now.These technology need the correction work being carried out abutment by a dental laboratory technician at laboratory; Or use alternative method, a doctor uses a provisional plastics abutment, revises according to the oral cavity of patient, is then delivered to laboratory and implements building of metal abutment based on provisional abutment.The program of these complexity significantly increases laboratory expense, reduces the profit about 1/4 to 1/3 of odontologist, also can spend the more expense of patient and time simultaneously.

Another problem is according to existing technology, and dental implant system needs a large amount of coordinating for the different restorative procedure in dentistry practice containing threaded prosthese corona adnexa.In the recent period, there are three kinds of main restorative procedures, fixed monomer or multiunit cement corona artificial tooth, detachable monomer or multiunit spiral indwelling artificial tooth, and detachable overlay denture.In order to the restorative procedure coordinating these different, need the stock having a large amount of different elements, then need to drop into a large amount of time and moneys for dental profession.

Implant another relevant problem with tooth remain surgeon and repair odontologist and do not have ability to select final abutment.Dental laboratory can determine that the analysis based on the plastic die of inserting patient's mouth needs the abutment of what type especially.This can hinder surgeon or repair odontologist has the ability observe and correct any angle problem or tissue thickness's difference problem.

From favourable angle, current invented technology provides a kind of dentistry and implants the new method of repairing, it illustrate numerous advantages, as simplify program, high performance-price ratio, minimizing queuing time, reduce 1-2 time laboratory access, and reduce hospital access.In some instances, the technology of present invention has the ability to make oral surgeon or repair odontologist at any time according to adjusting abutment, to obtain ideal form, delineates abutment.The method of this invention can complete in the office space of odontologist, adopts and can reach at gingiva tissue and corona once free from error level minimum after installing, reduces the demand of returning abutment system and debugging to odontologist's laboratory simultaneously.

Fig. 6 (i)---6 (vii) use exemplary method to illustrate aforementioned step (i) of carrying out Dental Erosion according to the present invention---(vii).Fig. 6 (i) explains step (i), according to this figure, secondary corona component 600 (such as Fig. 2 a---22 in 5b, 32,42 and 52) comprises a final abutment elements 601 (such as Fig. 2 a---23 in 5b, 33,43 and 53) and tooth transplantation assembly 602 (such as Fig. 2 a---24 in 5b, 34,44 and 54).By a part for secondary corona component 600---typical tooth transplantation assembly 602 is inserted in (as screwed in) patient's jawbone 699.The present invention can be used for replacing single tooth tooth or many teeth.When replacing single tooth tooth, routine techniques can be used first to carry out implantation position preparation.Position preparation may relate to boring work, and boring width is approximately tooth transplantation element width.Or implantation position also can use tapping to prepare the hole of an appropriate size, and thread size should be applicable to a screw thread tooth transplantation group part screws in this Kong Bingyu and implant in surrounding tissue.Many teeth are replaced and are usually used implantation device and implant crane span structure.Such as, the space that many hypodontias cause, available prosthese covers, and according to the one end revising final abutment elements in the secondary corona component of anchoring of the present invention, and its other end and natural tooth (or a tooth implants secondary corona component) is bonded.The prosthese being anchored in two ends serves as the effect of space " bridge ".

At the installation initial stage, tooth transplantation assembly cannot bear and normally chew strength.Only after implanted tooth peripheral support tissue grows, the prosthese of abutment elements and corona and so on can be installed.During this period, a closure screws may be inserted, thus keep transplanting tooth cleaning inside, preventing pollution surrounding tissue.As shown in Fig. 6 (i), the osseous tissue after a period of time in jawbone 699 combines with tooth transplantation assembly 602.Then, assemble secondary corona component 600, and be fixed together with the tooth transplantation assembly 602 of patient's cavity interior.In some practical operation, whole final abutment elements 601 can be revised, and therefore can be called can retouch.In other practical operation, it can retouch (be display that final abutment elements 601 comprises one, such as Fig. 2 a---23a, 33a, 43a and 53a in 5b) and one can not retouch (do not show, such as Fig. 2 a---23b, 33b, 43b and 53b in 5b).As mentioned above, final abutment elements 601 is made by without titanium; Assembly 601 according to the concrete oral environment of patient, can should customize by retouch (whole adjacent its part rear) by revising (frustrating as cut).

Fig. 6 (ii) illustrates step (ii), according to this figure, dentist can directly measure can retouch surface (such as final abutment elements 601 top) a position L1 and can beeline X1 around retouch between certain body surface (such as upper tooth 604).Measurement in patient's oral environment, or should be carried out in its mouth.

Fig. 6 (iii) illustrates step (iii), according to this figure, should compare X1 value and predetermined value Y1, wherein a Y1>0 after dentist.Such as Y1 is 2mm, then the minimum thickness installing corona at L1 place, position future is 2mm.If X1 >=Y1 (such as: X1=2.5mm), then sufficient space can be had to be greater than the corona of Y1 at L1 place, position installation thickness, and this corona will be very firm at L1 place, position.In such cases (i.e. X1 >=Y1), dentist does not need adjacent 601 of correction position L1 place.

Fig. 6 (iv) illustrates step (iv), according to this figure, if dentist finds X1<Y1 (as X1=1.5mm), then do not have sufficient space installation thickness to be greater than the corona of Y1 at L1 place, position, and this corona will be very not firm at L1 place, position.In such cases (i.e. X1<Y1), dentist must correction position L1 place adjoin 601.Dentist can in patient's oral environment until directly correction position L1 place can retouch (i.e. increase beeline X1, until X1 >=Y1), and do not need to shift out patient oral cavity by retouch.Such as, dentist can use drill bit 610 to cut from the abutment elements of position L1 and frustrate the part that a small thickness is at least 0.5mm.X1 is increased to 2.0mm from 1.5mm, makes X1 >=Y1.

Fig. 6 (v) illustrates step (v), according to this figure, if dentist finds to have the corresponding beeline Xn of a place or plurality of positions Ln to be less than respective predetermined values Yn (i.e. Xn<Yn) in retouch surface, wherein Yn>0, n is integer, and n >=2, dentist is necessary abundant above-mentioned steps (ii)---(iv) then, until the Xn >=Yn at Ln place, position.Now, dentist Complete customization well final abutment elements such as, dentist directly measure can retouch surface (injecting the side of final abutment elements 601) position L2 and can beeline X2 between the surface (such as adjacent teeth 605) of retouch surrounding objects.If X2<Y2 (i.e. X1=1.0mm and Y2=1.3mm), then the corona not having sufficient space to install thickness to be greater than Y2 at L2 place, position, and this corona (if installation) will be very insecure at L2 place.In such cases (i.e. X2<Y2), dentist must correction position L2 place adjoin 601.Dentist can in patient's oral environment until directly correction position L2 place can retouch (i.e. increase beeline X2, until X2 >=Y2), and do not need to shift out patient oral cavity by retouch.Such as, dentist can cut from the abutment elements of position L2 and frustrate the part that a small thickness is at least 0.3mm.X2 is increased at least 1.3mm from 1.0mm, makes X2 >=Y2.

See Fig. 6, diagram 6, according to the final abutment size customized in step before, dentist can adopt known method at that time, as: adopt impression tray 688, completely make corona 620 (as shown in Fig. 2 a-5b 21 according to particular patient dental cases, 31,41 and 51).

See Fig. 6, diagram 7, corona 620 to need to be attached in oral environment (in patient's mouth) on final abutment 601 (completely according to the customization of patient's abutment situation) subsequently, completes Dental Erosion.

Tooth transplantation material therefor requires strict, has higher bio-compatibility and tatanic.Planted teeth material is best and recommendation adopts growth (bone growth) type in Integrated implant or bone, also becomes ankylosing material.As: graft can be hollow or solid structure.Hollow structure contributes to the interior growth of bone of graft.In addition, graft can include hole, gos deep into its inwall to promote to grow in bone.Be required to be taper bottom graft, thus provide living load for whole dental bed periphery tooth and tissue.Such as: bottom pyramidal is about 2 ~ 3 grades.Graft bottom pyramidal, i.e. planted teeth diameter, should reduce from top to bottom gradually.

Planted teeth material should be selected from following combination: pure titanium, and titanium oxide, titanium alloy is (as TiAl ₆v ₄alloy), rustless steel, zirconium, vitallium, polymeric material and relevant reasonable combination.

In this invention certain embodiments, planted teeth is by biological stable polymeric material, and the medicament that this polymeric material includes.Medicament should diffuse to surrounding tissue from polymeric material, as osseous tissue and neighbouring tissue.In other words, medicament can locality or systematically spread in planted teeth by polymeric material.Medicament example includes but not limited to steroid anti-inflammatory drug, microorganism killing agent, antiviral complex (as acyclovir and interferon); Antiprotozoal drug (as chloromycetin and sulfamethoxazole); Analgesic; Steroid analgesic (as aspirin, salicylic acid, diflunisal, morphine and morphine salt); Anti-corrosion composition (as cetylpyridinium chloride, benzalkonium chloride, hibitane and similar medicament); Anti-fungal composition (as cetab); Antifungal (as Polyethylene Glycol, alkylaryl sulfonates, miconazole nitrate, metronidazole, trimethoprim); Local anesthetic (as procaine salt, anaesthesine, lignocaine, procaine, marcaine, tetracaine, lignocaine, Carbocainum and Carbocainum salt); Suppressing panting calming medicine (as epinephrine, ephedrine, epinephrine, aminophylline and theophylline); Anticoagulant (heparin and heparin sodium, as calcium and heparin sodium, dicoumarol); Depressor (as methyldopa, hydralazine, clonidine, chlorothiazide, timolol, PR, metoprolol, minipress and furosemide); And Verdoflavin, B12.C. steroid anti-inflammatory drug range of choices comprises: corticosteroid is (as hydrocortisone, hydroxyltriamcinolone, methyl dexamethasone, dexamethasone phosphate, beclomethasone, valerate clobetasol, (11BETA,16ALPHA)-16,17-[methylethylidenebis(oxy), desoximetasone, desoxycortone acetate, dexamethasone, dichlorisone, two vinegar dichlorisone, pentane acid double fluoro dragon-a/ible, fluadrenolone, the resistance to moral of fluorine chlorine, fluoxetine butylester, fluocortolone, acetate fluprednidene (fluprednylidene), flurandrenolide, halcinonide, hydrocortisone acetate, hydrocortisone butyrate, methyl meticortelone, triamcinolone acetonide, cortisone, cortodoxone, flucetonide, fludrocortisone, diacetate difluorosone, fluradrenolone, fludrocortisone, difluorosone diacetate, fluradrenolone contracting acetone, medrysone, amcinafel, amcinafide, betamethasone and balance lipid, chloroprednisone, chloroprednisone acetate, clocortolone, clescinolone, dichlorisone, difluprednate, flucioronide, flunisolide, fluorometholone, fluperolone, fluprednisolone, valerate cortisone, cyclopentyl propionic acid hydrocortisone, hydrocortamate, meprednisone, paramethasone, hydrogenation Bo Nisong, prednisone, beclomethasone, omcilon and composition thereof).The steroid anti-inflammatory drug of recommending is hydrocortisone.

In various example, the final abutment in the present invention need manufacture in advance, adopts raw material strictly firm, has biological compatibility, similar to patient's dentine.

Prefabricated or soft wavy abutment need carry out prefabricated according to the length of final abutment and angle, although also cannot be applicable to case used at present.Such as, current state-of-the-art abutment can be prefabricated into various required form, size, comprises cylindrical, bar shaped, cube, polyhedron, avette and dish type.

In a case, the final abutment of front tooth can be the flat abutment specially for labial teeth design, and reform of nature anatomical structure, meets mahalanobis distance (being greater than facial language distance).

Generally speaking, even if prefabricated final abutment nearly possesses profile and form accurately, still need and to repair further and profile process (or customization requirement) is fitted mutually, the expected product meeting particular patient oral environment can be produced.

Prefabricated final abutment finishing (or customized) success, also after meeting patient's oral environment, not only can make corona more agree with time corona, and can at utmost compensate unjustified situation between artificial tooth and adjacent teeth (if any).Following situation may cause tooth not line up: the compatible degree in planted teeth and gingival surface direction and adjacent teeth exist very large deviation.Same, existing invention can save the needs of abutment angle lap in previous processes, thus avoids tooth to be staggered.

Prefabricated final abutment is manufactured by factory, for ease of repairing the commercial product of (customization).But this abutment also can adopt traditional method (as molding) to customize.Professional person all knows, tooth mould can use waxed one-tenth.Wax can melt at burner hearth, makes die, after fuse into suitable material (as alloy) and make tooth mould.

Push away in case in choosing; at present for making the material of final abutment; no matter be combined separately or with the other materials making corona; whether there is protecting film; the optical characteristics induced one can be shown, therefore there are higher aesthetic values, can from color and luster; shade, transparency and translucence simulates the external appearance characteristic of natural teeth.Such as, the marginal gingiva of final abutment may have in the obvious scope of a circle and is not covered with corona.As these positions directly adopt metal or plastics to make, then can not dentulous gloss, toilet article can leave the refined vestige of impact patient facial region.

Although may adopt in the present invention and repair tooth material, with regard to aesthetic values, this Product Tendency is in selecting porcelain at present, composite and pottery but not pump alloy and metal, because the former is closer to the color and luster of adjacent teeth.

The transparency of human teeth reduces from enamel gradually to dentin.Equally, in recommendation case, the higher material of transparency is for making corona, and transparency and the lower material of colourity are for the manufacture of final abutment.

If necessary, final carriage assembly and corona can be formed according to more than one stain of recipe configuration, or wherein composition material, the tone of formation is similar to dentine and enamel.Such as, pink colour stain can be obtained by zirconia dissolves vanadium oxide, using as solid solution.Stain includes but not limited to Pr, the oxide of Er, Fe, Co, Ni, Ti, V, Cr, Cu and Mn, such as Fe2O3, Er2O3 and MnO2.Under specified conditions, also have Er2O3, Pr6O11, Fe2O3, ZnO and zirconic mixture, the tone of dentine can be allowed good.

For some patient, the physical characteristic of material, chemical characteristic and biological nature are more important than its aesthetic feeling possibly.Based on this, it is large that we are more prone to intensity, stable performance, there is good bio-compatibility and the material of chemical durability, substitute the function of natural teeth completely, physical characteristic can be kept for a long time, even if the liquid in contact oral cavity, such as acidic liquid also still can retention properties be stablized.As long as the material of the final support of tooth possesses recoverability, so from broadly seeing that perhaps to meet these specific.Such as, according to ASTM D-1474 standard, a canonical parameter of final timbering material is hardness H (a kind of in K.H.N, Knoop hardness number).Although the hardness range of dentine is little, i.e. 30-70K.H.N, the material of the final support of support generally to be equivalent to 10 K.H.N and more than, slightly good is be more than or equal to 30K.H.N, it is preferred that be more than or equal to 70K.H.N.

In Knoop hardness test, use certain dynamics, by diamond summit by certain time on the burnishing surface of experiment material, then with the impression that microscopic examination produces.Knoop hardness HK or KHN passes through formulae discovery: HK=carrying (kgf)/pressing area (mm ²)=P/ (CpL ²), and L=is along the impression length of major axis, the rectification factor that the shape of Cp=impression is relevant, and ideal value is 0.070279, P=load.But will know except Knoop hardness, also have other method to weigh hardness and the intensity of material, other balancing methods have also been used in this invention.Such as, mohsscale is the method for the marresistance weighing various material, namely draws softer material with harder material.In a kind of situation, the Mohs' hardness from about 2.0 to about 5.8 of final scaffold component.In other cases, the Mohs' hardness from about 6.2 to about 9.8 of scaffold component.

In some cases, often select directly can to repair in the oral environment of patient, can in finishing in a short time and moulding, also can to repair again and final timbering material moulding again, like this, the trouble of wear corrective instrument can just be eliminated, also without any side effect.

In some preferred version, the direct finishing of final scaffold component is also without any side effects, the heat shock of such as jawbone.Because we can effectively control finishing means, make the heat of generation little; And the heat transmitting of support and embedded material is very low, jawbone can not be transferred heat to.And, heat can be controlled with cooling system if desired, jawbone is played a protective role.Better scheme uses without the preparation material of titanium material as scaffold component.

Not there is microcrack in final scaffold component, in addition, also have biocompatibility in dressing process, can not cause rejection, corrosion of can not degrading in oral environment, and intensity is enough to the mastication coordinating corona, also meets esthetic requirement.

The present invention step (such as above-mentioned steps 2) has directly weighed beeline X1, namely oral environment L1 position final scaffold component surface and around the beeline between material surface, the material around final scaffold component can be periodontal tissue, gingiva tissue, tooth, prosthese wherein one or more.Estimate the maximum gauge of minima close to the following corona of L1 position of X1.Experienced dentist knows and strict thickness must be taked control to corona, finally to repair " tooth ", makes it adapt to oral environment and obtain good function.Such as, corona final scaffold component thickness may 1mm to 3mm not etc., specifically depending on biting strength, and finally the surrounding thickness of support can from 0.01mm to 0.5mm not etc.According to different thickness requirements, dentist or computer can determine the predetermined value Y1 (if necessary, Y2, Y3, Y4 etc.) in ad-hoc location L1 (if necessary, L2, L3, L4)

If X1<Y1, the thickness of the corona so in L1 position possibly cannot meet the thickness requirement of position surrounding.After having had this invention, final scaffold component can directly carry out repairing or moulding (need not take outside oral cavity) on L1 position, oral cavity, extends minimum range X1, until X1 >=Y1, in other words, namely meets the thickness requirement of position L1.

Position L1 and Ln, from broad terms, not only refers to a point, also can refer to the small size scope on final scaffold component surface to be repaired, such as 0.5mm ², 1.0mm ², 2.0mm ²etc..

On the surface of final scaffold component, position to be repaired can be one or more, such as, dentist may need directly to repair 3 places in the surrounding of final scaffold component: L1, L2 and L3, repairs 2 places: L4 and L5 on the top of final scaffold component, eachly correspond to beeline X1, X2, X3, X4 and X5; Corresponding predetermined value is Y1, Y2, Y3, Y4 and Y5.

In different schemes, the direct reparation means of final holder part comprise mechanical means, chemical method, and the optical means of such as cut and UV degraded, such as, control the thermal methods heated, or wherein several method comprehensively uses.Various modification means include but not limited to cutting, engraving, cross cut, grind, mill, deburring, adjustment, polish, polishing, polishing, control are evaporated, remove, moulding, discharging milling (EDM), water spray or cut etc.Such as, veteran dentist can use instrument (such as hand tool) directly to repair, such as, bore or rotary file; Diamond; Multifunctional diamond bur; Dentistry carbide bur, such as tungsten carbide drill steel manufactures; Dental firing diamond is filed; Tapered file; Dentistry diamond chain wheel; Tungsten carbide cutter; Parallel milling cutter; Dentistry file etc. also can be wherein several comprehensive use.File sheet can be circular, colyliform, inverted cone, straight crack, taper crack, amalgam preparatory course, pyriform, flame-shaped, taper, egg type, is tapered, bullet shaped, needle-like, straight crack cross cut, taper crack cross cut, holds to cross cut, straight dome, straight dome cross cut and taper cross cut.Such as, carbide tool (standard) may be used for repairing lucite, stone and Gypsum Fibrosum; Carbide tool (coarse) for repairing lucite fast, stone and Gypsum Fibrosum.Carbide tool (hyperfine) for metal, lucite and stone polishing deburring; Laboratory carbide tool (meticulous) cross cut may be used for metal, lucite and Gypsum Fibrosum deburring; Metal, lucite and stone that fly-cutting is all; And cut down lucite and Gypsum Fibrosum fast.In dressing process, contact area should keep dry, or rinses through lubricant or soak.Some can with air or airflow scouring.Well-known liquid lubricant comprises water, oils, glycerol, glycol and silicone.
