Embodiment
In order to describe structure of the present invention and characteristics place in detail, lift with two preferred embodiments and the conjunction with figs. explanation as after, wherein:
As shown in Figure 1, the supporting tooth design method by digital of a kind of digital tooth implantation technology that the present invention's first preferred embodiment is provided mainly has the following step:
A) tooth implantation planning: as shown in Figure 2 to Figure 3, carry out tooth implantation planning, make and plant the optimum position that body 11 (being shown in Fig. 4) is implanted in the tooth place according to the numerical data that sufferer loads in the computer system.Wherein, this computer system has the data of the oral cavity digital model of sufferer, and sets up a digital gum 13 and digital corona 23 in this oral cavity digital model.This numeral gum 13 and digital corona 23 can be loaded by a numerical data base (not shown) that is stored in this computer system.Or produce gum/corona model according to sufferer oral cavity form, again the numerical data that gum/corona scanning is produced is loaded.
B) set up referential digital abutment tooth:, plant the tooth place in this and set up a referential digital abutment tooth 15 to shown in Figure 6 as Fig. 4, and this referential digital abutment tooth 15 is positioned this and plants body 11.This referential digital abutment tooth 15 is loaded by this numerical data base.
C) adjust referential digital abutment tooth: this referential digital abutment tooth 15 has a gum bottom 152, an and gum top 153 that is positioned at these 152 tops, gum bottom, angle between this gum bottom 152 and the gum top 153 is to reset to put according to best breast to adjust, the size on this gum top 153 is to adjust according to the size of this numeral corona 23, this gum bottom 152 has an end face 1521 and a bottom surface 1522, this end face 1521 is by drawing the gum line at this numeral gum 13 (being shown in Fig. 2), and be consistent with the shape on this numeral gum 13 surfaces of putting of resetting at breast, with end face 1521 forms of setting this gum bottom 152.This gum top 153 is upwards to be shaped by this end face 1521, and the form of this bottom surface 1522 is with to plant body 11 end faces corresponding mutually, the location so that both are mutually combined.When adjusting, in consideration is also included the force direction that is subjected to of interlock with the adjustment of gum top 153 angles in this gum bottom 152, and to adjust best angle, the state that adjustment is finished as shown in Figure 7.And this interlock to be subjected to force direction be digital corona 23 interlocks the time stressed axially.As shown in Figure 8, this is stressed axially when definition, in present embodiment, be to sting the head place in this numeral corona 23 to take out 3 points respectively, be defined as a biteplane H, and be reference point with the nest of stinging of this numeral corona 23, define a straight line X perpendicular to this biteplane H, when this straight line X promptly is these numeral corona 23 interlocks stressed axially.Again, in above-mentioned adjustment process, put the drift angle that can cause this gum top 153 when excessive if breast that should numeral corona 23 resets, the corona that then may cause real product when mounted can and gum top 153 between stressed uneven problem is arranged.And as shown in Figure 9, by the size (being to dwindle example among the figure) on the gum top 153 of adjusting this referential digital abutment tooth 15, and the size of adjusting this numeral corona 23 to be cooperating this gum top 153, with absorb 153 drift angles, gum top big the installation question that may cause.
D) finish a numeral platform tooth: this referential digital abutment tooth 15 promptly forms one and waits to plant a numeral platform tooth after adjustment is finished, and is shown in Fig. 7.Can be for exporting a manufacturing system to and produce a platform tooth finished product as follow-up.
By above-mentioned steps, can by the digital tooth implantation technology come actual plant tooth before advanced professional etiquette draw, and set up digital gum 13 and digital corona 23, produce adjusted gum top 153 and gum bottom 152 by this numeral gum 13 and digital corona 23 again, to finish a numeral platform tooth.Can produce a platform tooth finished product via exporting a manufacturing system to.This platform tooth finished product promptly can be used to directly plant tooth when planting tooth, and this platform tooth finished product can being subjected to force direction of corresponding interlock and convenient follow-up artificial tooth is made.
As shown in figure 10, the supporting tooth design method by digital of a kind of digital tooth implantation technology that the present invention's second preferred embodiment is provided is taken off first embodiment before mainly generally being same as, and difference is:
In step c), the end face form of this gum bottom 152 ', mainly be that gum bottom 152 ' bottom surface periphery with this referential digital abutment tooth 15 ' is a benchmark, upwards expansion is extended and is intersected generation one closed region A with this numeral gum 13 ', and this closed region A is the end face 1521 ' form of the gum bottom 152 ' of this referential digital abutment tooth 15 '.
Take off first embodiment before all the other steps of this second embodiment and the effect that can reach all generally are same as, hold no longer to give and give unnecessary details.
As from the foregoing, tunable integers word of the present invention props up platform tooth angle degree, and then produce a platform tooth finished product of proper angle, and then make that follow-up angle of articulation of planting tooth is more accurate, artificial tooth is better to the function of stinging, and also promoted the aesthetic function of planting artificial tooth behind the tooth, follow-up artificial tooth promptly can be more simple on making.Simultaneously, also solved in the prior art, might artificial tooth plant the problem of tooth failure, and then solved the problem that bone that prior art may run into is integrated.
