[0030] According to one embodiment of the present disclosure, as figure 1 As shown, it provides a preparation method of denture veneer, the method comprises the following steps:
[0031] S1: Obtain the patient's oral data file,
[0032] S2: generate a phantom data file and a veneer data file according to the oral data file,
[0033] S3: According to the die data file and the veneer data file, use a 3D printer to obtain the die and veneer green body,
[0034] S4: Put the die and veneer green body into an incubator at 80-120°C for 0.5-3h,
[0035] S5: Place the heat-preserved die and the veneer green body respectively in a furnace at 800-1000°C for 10-100 minutes to obtain the primary sintered die and veneer, respectively.
[0036] S6: Place the primary sintered veneer on the primary sintered die, and perform secondary sintering at 900-1000° C. for 5-30 minutes to obtain the desired denture veneer.
[0037] According to the above method, a high-precision denture veneer can b...
