Method for making digital model applied to artificial dental implant and method for making dentures

Technical field:

The invention belongs to the technical field of artificial teeth, in particular to a method for making a digital model applied to artificial teeth and a method for making dentures.

Background technique:

After the osseointegrated wound heals in the artificial dental implant surgery, dentures must be made to complete the entire course of treatment. The traditional method of denture products is that after the patient's osseointegrated wound has healed, the dentist uses silicone material to let the patient bite out a silicone mold, and then turn the silicone mold into a mouth model. The oral cavity model is made from a silicone mold, which is prone to errors during the conversion process, and the processing time is long, and the resulting oral cavity model is not accurate enough.

In the prior art, after the oral cavity model is converted, the oral cavity model needs to be sent to a laboratory for making denture products. For the production of dental implants and dentures, the laboratory must first complete the artificial support teeth or rods, and then continue to produce crowns and gums. However, the above-mentioned denture production process is quite time-consuming, because the dentist must first send the silicone mold or oral cavity model to the laboratory, and the laboratory must also make artificial support teeth or rods before making crowns and gums to complete the denture production process .

Some manufacturers on the market have designed oral three-dimensional digital scanners, which can directly scan the patient's oral cavity, and replace the operation of the patient's silicone mold by obtaining oral digital data, saving time and reducing production costs for dentures. However, this oral three-dimensional digital scanning machine can only be applied to the production of general dentures, and cannot be applied to the production of dentures of patients after dental implant surgery.
