Abstract
The invention discloses a CAD and CAM personalized substrate sandwich ceramic bracket, which can increase the fit between the ceramic bracket as well as a tongue side bracket and the dental face, so the binding strength of the bracket and the dental face is increased. The CAD and CAM personalized substrate sandwich ceramic bracket consists of a personalized bracket base (1) which is matched with a finished ceramic bracket and completely jointed with the lip face or tongue face of a tooth body and the bottom face of the finished ceramic bracket, a binder (2) and the finished ceramic bracket (3), wherein the thickness of the substrate is 0.4 to 0.6 centimeters; the ceramic binder (2) binds the personalized bracket base (1) and the finished ceramic bracket (3) into a whole; and the thickness of the ceramic binder (2) is kept between 30 and 50 micrometers.
Description
Technical field
The present invention relates to a kind of bracket and manufacture method, be specifically related to personalized sandwich ceramic bracket of substrate sandwich of a kind of CAD, CAM and manufacture method, belong to the biomedical material application.
Background technology
In recent years, the dental prosthetics development is rapid, especially mouth cavity orthodontic treatment, and the patient is the original intention of prescription on individual diagnosis to improve attractive in appearance often.But the patient is to the requirement of orthodontic treatment and not only rest on improvement attractive in appearance after rescuing, and the requirement of rescuing in the process attractive in appearance is also more and more higher.Adult adding has broken through the forbidden zone of orthodontic treatment in the last hundred years, widened the field of orthodontic treatment, a series of problems have also been produced thereupon, one of them is exactly some adult owing to reason such as social, professional, attractive in appearance, aesthetic property to appliance is had higher requirement, and wishes to occur " orthodontic treatment attractive in appearance ".This just requires orthotic device not only will reach the target that patho-occlusion is rescued, also should be more attractive in appearance, hidden, meet a part of patient especially adult female patient's physiology, psychological need.
Based on above reason, ceramic bracket and linguoplate groove arise at the historic moment, and it is poor that finished product labial surface ceramic bracket exists with natural teeth facing adaptation, the shortcoming that adhesive property is not good, and clinical manifestation is higher expulsion rate and jackknifing rate.Ceramic bracket and adamantine bonding can be divided into two kinds at present, and a kind of is chemical bond, and a kind of is mechanical bond.Discover that in a large number ceramic bracket and adamantine mechanical bond undercapacity have higher expulsion rate, and chemically combined intensity are excessive, cause adamantine destruction during down to the removal bracket.And that tongue side metal bracket also exists with the facing adaptation is poor, shortcomings such as adhesive property is not good, therefore need development new product and manufacture method,, solve problems of the prior art and deficiency to improve the bond strength of ceramic bracket and linguoplate groove and facing.
Summary of the invention
It is poor to the objective of the invention is to solve the bracket and the natural teeth facing adaptation that exist in the prior art, the problem and shortage of the not good grade of adhesive property, provide the personalized substrate sandwich of a kind of CAD, CAM sandwich ceramic bracket, the sandwich ceramic bracket of the personalized substrate sandwich of this CAD, CAM can increase the adaptation of ceramic bracket and linguoplate groove and facing, thereby improves the adhesion strength of bracket and facing.
The present invention also provides the manufacture method of the sandwich ceramic bracket of the personalized substrate sandwich of CAD, CAM, and method is simple.
The present invention is achieved by the following technical solutions:
The sandwich ceramic bracket of the personalized substrate sandwich of CAD of the present invention, CAM, it is by constituting with finished product ceramic bracket coupling and with personalized bracket substrate 1, binding agent 2 and the finished product ceramic bracket 3 fitted fully in tooth body labial surface or lingual surface and finished product ceramic bracket bottom surface, the thickness of substrate is 0.4～0.6cm, vitrified bonding 2 is bonded as one personalized bracket substrate 1 and finished product ceramic bracket 3, and the THICKNESS CONTROL of binding agent 2 is at 30～50 μ m.The material of the personalized bracket substrate 1 described in the present invention is preferably plastics or pottery.
The manufacture method of the sandwich ceramic bracket of the personalized substrate sandwich of above-mentioned CAD of the present invention, CAM, it may further comprise the steps: A) use scanner to obtain tooth body labial surface or tooth body lingual surface shape information, degree of accuracy reaches 0.02mm, guaranteed the accuracy of model, so personalized substrate and facing and the driving fit of bracket bottom level;
B) according to scanning gained facing form, adopt CAD, CAM software to generate at the bottom of personalized lip side or the tongue side group;
C) finish plastic-substrates or finish ceramic bases by the rapid prototyping device fabrication by the manufacturing of turnning and milling complex centre;
D) by vitrified bonding personalized substrate and finished product ceramic bracket are bonded as one again, promptly get the sandwich ceramic bracket of the personalized substrate sandwich of CAD, CAM.
Compared with prior art the present invention has following beneficial effect:
The increase of made of the present invention the adhesion strength of bracket and facing, existing ceramic bracket and enamel mechanical adhesion deficiency and the strong excessively phenomenon of chemical bonding have been improved, both increased the mechanical adhesion intensity of bracket and facing, when having avoided the removal bracket again to adamantine destruction.In addition, the making of personalized bracket substrate also makes finished product labial surface ceramic bracket also can be used for the tongue side, use CAD, CAM software to make personalized bracket substrate according to the lingual surface form, this personalization substrate can as much as possiblely hold lingual surface, bracket substrate and facing are identical, have good facing fitness and adhesion strength.Be the individual tongue-side ceramic bracket after the finished product ceramic bracket bonding, compare more attractive in appearancely with the individual tongue-side metal bracket, adhesive property is better, and has avoided because of metal retains in the electrolyte environment of oral cavity for a long time, the potential hazard that human body is caused.Manufacture method of the present invention in addition is simple, easy to make.
