Specific embodiment
In order to describe the technical content, the structural feature, the achieved object and the effect of this invention in detail, below in conjunction with embodiment
And attached drawing is cooperated to be explained in detail.
It please refers to Fig.1 to Fig.3, a kind of production method for wearing dental case mold, comprising:
S1, the 3 d image data for obtaining patient's denture generate virtual dental arch model according to the 3 d image data of denture,
Specifically, being generated according to denture 3 d image data virtual by the denture 3 d image data of scanner scanning patient in mouth
Dental arch model, the virtual dental arch model include virtual upper dental arch model and virtual mandibular dentition model.
The oral cavity structure being related in the technical scheme is denture, and denture includes multiple teeth, and multiple teeth is successively close
The denture of arc is formed after arrangement；
In addition to the denture 3 d image data with scanner scanning patient in mouth, can also be obtained by PVS modulus mode
Patient's dental arch model is converted to the 3 d image data of patient's denture by patient's dental arch model, further according to the three-dimensional of patient's denture
Image data generates virtual dental arch model.
S2, firstly, position between the virtual upper dental arch model of adjustment and virtual mandibular dentition model, simulates patient's occlusive state
When virtually upper dental arch model and virtual mandibular dentition model relative position, then on the pseudo-wear dental cast of virtual dental arch model
Addition is virtual to repair block models, such as when abrasion tooth is in virtual mandibular dentition model, the virtual lower end for repairing block models and virtual
The upper end adaptation of dental cast is worn, the virtual upper end for repairing block models is according to the corresponding virtually upper dental arch model of pseudo-wear dental cast
The adjustment of virtual tooth mould shapes, specifically, carry out cutting finishing processing to the virtual upper end for repairing block models, be allowed to it is right
Should the virtual tooth model of virtual upper dental arch model will not clash, finally by after finishing virtual reparation block models and abrasion
Dental cast merges locking, to obtain virtually repairing tooth model；
S3, the virtual coronal model of generation on tooth model is virtually being repaired, the virtual coronal model is equipped with for wrapping
The virtual recessed portion for repairing tooth model is wrapped up in, determines the relative angle of virtual coronal model and pseudo-wear dental cast for convenience
And relative distance, virtual coronal model support bar is generated on virtual coronal model respectively, is generated on pseudo-wear dental cast
Pseudo-wear dental cast support rod, the virtual coronal model support bar are oppositely arranged with pseudo-wear dental cast support rod, and
In contact condition, so virtual coronal mould can be determined according to virtual coronal model support bar and pseudo-wear dental cast support rod
The relative angle and relative distance of type and pseudo-wear dental cast, to ensure that virtual coronal model and pseudo-wear dental cast
Between reparation block shape and size meet original design；
It should be noted that being the prior art according to the virtual virtual coronal model of tooth model generation of repairing, it is based on
The medical softwares such as iOrtho and Clincheck can be generated according to virtual reparation tooth model virtual coronal in several ways
Model, therefore, the present invention is to how according to virtual reparation tooth model generation, virtually coronal model is further elaborated.
S4, the pseudo-wear dental cast in virtual coronal model and virtual dental arch model is subjected to 3D printing respectively, is obtained
Coronal mold and abrasion tooth mold；
It should be noted that according to the three-dimensional figure of the pseudo-wear dental cast in virtual coronal model and virtual dental arch model
As data progress 3D printing, obtaining coronal model and abrasion dental cast is the prior art, can be according to 3 d image data by melting
Melt the modes such as deposition rapid forming, Stereolithography and three-dimensional powder bonding and prints coronal model and abrasion dental cast, therefore,
The present invention not to how to coronal model and wear dental cast 3 d image data carry out 3D printing be further elaborated.
After step s4, further include the steps that for coronal mold being socketed on abrasion tooth mold, coronal mold is socketed on
Tooth mold is worn, according to the abrasion dental cast support rod on the coronal model support bar and abrasion tooth mold adjusted on coronal mold
Relative position, determine coronal mold and wear tooth mold relative angle and relative position, specifically, by coronal mold
Coronal model support bar is aligned with the abrasion dental cast support rod on abrasion tooth mold, and the coronal model support on coronal mold
It is the standard that coronal mold is socketed on abrasion tooth mold when bar is in contact with the abrasion dental cast support rod on abrasion tooth mold
True position, then the potting resin between coronal mold and abrasion tooth mold, obtains dummy.
It should be noted that the potting resin between coronal mold and abrasion tooth mold, obtains dummy and belongs to existing skill
Art, therefore, the present invention not to how coronal mold and abrasion tooth mold between potting resin be further elaborated.
As can be seen from the above description, the beneficial effects of the present invention are: it provides a kind of digitlization occlusal reconstruction abrasion tooth and repairs
The method of complex mold can reduce the making step of abrasion dental case mold using this method, and the consuming time is short, for mill
Shape, the size of damage dental case mold can accomplish more accurately control, reduce number of doing over again, gone out by the Mold Making
Abrasion dental case mould appearance it is more aesthetically pleasing, also more be bonded patient abrasion tooth, alleviate the workload of doctor, increase
The satisfaction of patient.
The invention further relates to a kind of abrasion dental case mold, the abrasion dental case mold uses above-mentioned abrasion tooth
The production method for repairing mould is made, which includes coronal model 1 and tooth model 3, described
The lower end of coronal model 1 is equipped with groove, and the side of the coronal model 1 is equipped with coronal model support bar 2, the tooth model 3
Side be equipped with tooth model support rod 4, coronal model 1 is socketed on the tooth model 3, and by coronal model support bar 2
It is docked with tooth model support rod 4, is formed with dummy accommodating cavity between coronal model 1 and tooth model 3.
Among the above, up, down, left, right, before and after only represents its relative position without indicating its absolute position.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
