Description
Technical field
The disclosure relates generally to dentistry Design of digital field, more particularly to artificial intelligence dentistry CAD system
System and method.
Background technology
Because everyone teeth patterning is different, Gu and medically each dentistry case is required for special design to repair
Body.The form that traditional dentistry makes dummy is the lost-wax process used, and this method is doctor in disease displacement tooth mill
After falling (such as Fig. 1), the oral cavity model of patient is taken out using moulage in patient oral cavity, then turn by gypsum former formpiston
Change, produce the plaster cast the same with patient oral cavity.Then, lost-wax process makes a dummy on the plaster cast
The wax pattern or plastic pattern (by melting wax or plastics, solidifying dropwise, sanding and polishing obtains afterwards) of shape, then with embedding
Material embeds wax-pattern, and after high-temperature process, wax melts the mold cavity to form a reparation shape, reuses the sides such as high temperature centrifugation
Normal direction is repaired in the die cavity of shape and is cast into metal.After cooling, you can the metal restoration cast out is obtained, finally in metal
Dummy surface is handled, and completes final reparation volume morphing.
Traditional lost-wax process, Occlusal contact that is time-consuming and being difficult to acquisition and tooth conjunction face good apposition.Appearance slowly
Digitized preparation method.
CAD/CAM (CAD, Computer Aided Design/ computer-aided manufacturing, Computer
Aided Manufacturing) be computer integrated manufacturing system chief component, the technology is widely used to industry
The various fields such as production, architectural design, mass of object property calculation.1971, French dentist Duret and several computer elites
CAD/CAM system model machine is directed to together, is gone out first full porcelain tooth with the equipment making within 1985 and is preced with, CAD/CAM systems in 1988
Controlling manufacturing apparatus commercialization, it is incorporated into oral cavity and fixes in the design and fabrication repaired, triggered oral restoration educational circles one great
Technological revolution.The revolution of production technology has also necessarily driven the rapid development of materialogy, and bioceramic is applied to oral restoration
Learning domain variability with its good biocompatibility, outstanding aesthetic properties enjoys people to pay close attention to, and CAD/CAM promoting technologies can be cut
The development of ceramics is cut, several matched ceramic systems occurs.
CAD/CAM system is with various 3-dimensional scanning means, with light electrical principles and digital processing system, by patient's mouth
Chamber model is calculated by scanner and computer, and a 3-dimensional model the same with patient's oral cavity model is formed in computer (such as
Fig. 1).Substitute tradition and " physical impression " and " physical model " are obtained by moulage.Wax pattern (or shaped plastics) will be used to make disease
Become bit model, be changed into 3-dimensional graphic system, design lesion bit model (such as Fig. 2) on computers.Cursor movement is monitoring
Drawn on screen and repair volume graphic.Paraffin is cast into art, filling technique making dummy is changed into and formed by pattern digitization processing
The Digit Control Machine Tool of instruction control mill out dummy, patient's can of once going to a doctor completes repairing and treating.There is the Duret of France
System, the Rekow systems of Univ Minnesota-Twin Cities USA, the Cicero systems of Holland, the Cerec systems of Switzerland, Sweden
Procera systems, Lava systems of Minnesota Mining and Manufacturing Company etc..Technically be not quite similar between different system, the difficulty of operation and
Speed, the material used, the accuracy and aesthetic property of dummy are also different.
But at present, CAD/CAM system, there is a problem：After doctor establishes patient oral cavity 3-dimensional model in computer, repair
Complex is designed by being accomplished manually, i.e.,：Gone to operate 3-dimensional PaintShop by people, adjust each seed ginseng of dummy to be designed
Number 3-dimensional parameter, so that the dummy that final design goes out, meets that patient uses enough.And this process needs what is enriched very much
Dentistry design experiences, operating personnel need could be on duty by a large amount of trainings.

Tooth both sides tooth axial angle is identical；
Wherein, the X-axis is the horizontally arranged axis of orientation of tooth, and the Y-axis is thickness of tooth axis of orientation, and the Z axis is tooth
Tooth height axis of orientation, the A shaft angles degree are around the X-axis anglec of rotation, and B axle angle is around the Y-axis anglec of rotation.
The data of dummy mainly include its length, width, height, anglec of rotation etc., and it corresponds to XYZ shaft lengths,
AB shaft angle degree.According to the length for suffering from tooth both sides tooth and determining dummy, dummy, which is arranged on, suffers from tooth position needs and both sides tooth
Certain gap is stayed, the height of dummy takes the average value of both sides tooth height, and thickness also takes the average value of both sides thickness of tooth,
If suffering from the tooth that tooth is most edge, it is identical to suffer from dental case value tooth adjacent thereto.
Further, " the initial three-dimensional data file is shown as into 3-D graphic " is included the initial three-dimensional data
File carries out decoding generation figure and comes out the figure shows of generation.
Further, " the dummy three-dimensional data file is shown as into 3-D graphic " includes the dummy is three-dimensional
Data file carries out decoding generation figure and comes out the figure shows of generation.The figure that Three-dimensional Display is carried out in the present embodiment is equal
It has been shown that, user can intuitively be observed, and above-mentioned three-dimensional data file carries out decoding and shown.
Method disclosed in the present embodiment completes tooth design by using the mode of artificial intelligence by computer, without artificial
Operation, veteran personnel are substituted with computer and do tooth design, time saving and energy saving by the automatic computing of computer, can
The time of operating system is effectively reduced, improves the efficiency of user；Varying level operating personnel operation can be effectively reduced simultaneously
