Description

Preparation mold and method for denture supporting seat Technical Field The invention belongs to the technical field of denture supporting seat preparation, and particularly relates to a preparation mold and a preparation method of a denture supporting seat. Background The implant is a technology which has been developed faster and newer in recent years, and is characterized in that an implant is implanted in an alveolar bone, after the implant and the alveolar bone form bone combination, the implant is then inserted, in the process of inserting teeth, a denture placement device (i.e. a supporting seat) needs to be prepared, a denture is taken out from a package and placed on the supporting seat, and finally, the process of inserting teeth is performed. The supporting seat is downwards provided with a containing groove from the top, and can be used for placing false teeth. The existing support seat is usually divided into several parts for easy preparation, and the parts are connected and molded in the final step. This results in the support seat being prone to cracking after a period of use, thereby reducing the service life. Disclosure of Invention The invention aims to provide a preparation mould and a preparation method of a denture supporting seat, wherein the integrated supporting seat is obtained in a forging mode, so that the cracking probability is reduced, and the service life is prolonged.
