Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
As Figure 1-3, the stealthy tooth bracket of a kind of tongue side that the present invention is provided, including bracket base 1 and bracket body
2, wherein bracket base 1 includes flank 11 and tongue side face 12, and flank 11 is the curved surface being adapted with tongue side tooth curved surface, tongue
12 bracket body 2 is provided with sideways, bracket body 2, which is provided with, is used for the groove 21 that arch wire 3 is passed through.
Further, the bottom of bracket body 2 is provided with gum side's wing 22.Gum side's wing 22 is used to fix arch wire 3, in use, logical
Cross rubber band to fix arch wire 3 with gum side's wing 22, it is ensured that the not play of arch wire 3.
The stealthy tooth bracket of the tongue side is molded by 3D printing.
As shown in figure 3, the stealthy tooth bracket of multiple tongue sides is connected by arch wire 3, the integral dental aligners of shape.Each
Bracket body 2 is provided with one or two groove 21.
In one embodiment of the invention, the thickness of bracket base 1 is 0.3mm-0.4mm.Tongue side stealth tooth bracket is used
Cochrome material, arch wire 3 uses Ni-Ti marmems.The quantity of stealthy tooth bracket is according to the tooth numbers of patient
It is determined that, the shape of each stealth tooth bracket is adapted with corresponding tongue side tooth curved surface respectively.
The processing method of the stealthy tooth bracket of the tongue side, including following steps：
1) patient teeth's model is obtained by CT scan, be arranged in patient teeth's model preferably by arranging under tooth software
Correction state, and carry out under preferable ordered state the design of stealthy tooth bracket；
2) the tongue side tooth surface information of tooth model is extracted by 3 d modeling software, and according to tongue side tooth curved surface
The shape of the stealthy tooth bracket of the tooth model Design of State of information and ideal alignment；
3) designed personalized stealthy tooth bracket is assembled on the tooth model for being arranged in perfect condition, carried out whole
Body is optimized and revised；
4) according to the shape of the lingual bracket 1 of design, stealthy tooth bracket is molded by 3D printing；
5) press mold that carried out disinfection to stealthy tooth bracket processing.
Further, in step 1) in, it is the treatment that necessary tooth body dental pulp periodontal is carried out by clinical diagnosis first,
Ensure to rescue process dens in dente volume morphing, Periodontal Status stabilization.By laser or the industrial CT scan of high accuracy, 3-dimensional digital is obtained
Tooth model, then patient teeth's model is lined up into preferable effect by arranging tooth software (prior art) according to the diagnosis of dentist.
It is that patient teeth is lined up into preferable state to arrange tooth, and this process needs dentist accurately to judge patient symptom, and proposes
Rational solution, is reasonably adjusted under the guidance of dentist to patient teeth's model in row's tooth software.
In step 2) in, the stealthy tooth bracket of design comprises the following steps：
A. the thickening that 0.3mm-0.4mm is carried out to tongue side tooth curved surface is handled；
B. according to the shape of tongue side tooth curved surface, the curved surface extracted cut, so as to obtain size and shape
The suitable bracket base 1 of shape；
C. bracket base 1 is separated with tooth model；
D. design bracket body 2 and thereon groove 21.Operated by sketch drafting, projection, stretching, excision, chamfering etc.
Into the three-dimensional modeling of bracket body 2, need to ensure that each bracket bottom surface keeps balance during bracket groove floor design.
In step 4) in, stealthy tooth bracket uses Selective Laser Sintering machine-shaping, and printing precision reaches
0.05mm.After the completion of stealthy tooth bracket printing, buffing processing is carried out to its other outer surface in addition to flank 11.
The material that the stealthy tooth bracket is used is cochrome, and its stability is good, the probability of gum black line occurs
Low, good biocompatibility, with good mechanical property and moderate cost, cost performance is high；Burnt by selective laser
Knot technology machine-shaping, former is Germany EOSINT M290, and printing precision is up to 6 microns, it is ensured that the curved surface and tooth of processing
Tooth surface has higher compactness；After the completion of individual tongue-side stealth tooth bracket printing, cotton piece buff has been carried out to its outer surface
Polishing so that tongue side face is more smooth, eliminates the damage that may be brought to tongue, while making patient more comfortable.
The flank 11 of bracket base 1 is not processed by shot blasting, remains metal 3D printing completed state, and its surface has
Even densely covered metallic particles, increases the contact area of flank 11 and dental surface.
The design thickness of bracket base 1 is 0.3mm-0.4mm, greatly reduces the overall dimensions of tooth bracket, makes patient more
Plus it is comfortable
Reference patient dental features, the design for rescuing experience and bracket of dentist carry out meticulous design to arch wire.Bow
The material of silk 3 is Ni-Ti marmems, and the super-elasticity of Ni-Ti marmems causes in loading and uninstall process
