Preparation mold and method of a denture support seat

technical field

The invention belongs to the technical field of preparation of a denture support seat, and in particular relates to a mold and a method for preparing a denture support seat.

Background technique

Dental implant is a relatively new technology that has developed rapidly in recent years. It is to implant implants in the alveolar bone. Prepare the denture placement device (that is, the support base), take the dentures out of the package and place them on the support base, and finally carry out the denture process.

The support base has a receiving groove from the top down, and the denture can be placed. The existing supporting seat is usually divided into several parts for the convenience of preparation, and several parts are connected and formed in the final step. This causes the support seat to crack easily after being used for a period of time, thereby reducing the service life.
