PROCESS FOR THE FORMATION OF DENTAL PROSTHESES AND/OR SUPPORT STRUCTURES FOR DENTAL PROSTHESES, SUCH AS BRIDGES AND/OR THE LIKE, PROCESS FOR MAKING DENTAL WAFERS AND/OR SIMILAR STRUCTURES AND DENTAL WAFER FOR THE FORMATION OF DENTAL PROSTHESES

摘要

A process (100) for the formation of dental prostheses (1) and/or support structures therefor comprises making (101) a dental wafer (1) and removing (102) a predefined quantity of material, according to a three-dimensional reference model, from such a dental wafer (1). The making step comprises overlapping (101a) two or more layers of formation (2a), pre-imbued or to be imbued with thermosetting resin or a thermoplastic resin, wherein at least one of the layers of formation (2a) comprises graphene and/or carbon fibre and/or glass fibre; compressing (101b) one layer of formation (2a) against the other to join these and break any micro air bubbles present; heating (101c) the layers of formation (2a) to harden them and form the dental wafer (1) and finish the wafer (1). A process is also described for making dental wafers (1) and a dental wafer (1) that comprises graphene.

1. Process for the formation of dental prostheses, support structures for dental prostheses, such as bridges and the like, comprising the following steps:
making at least one dental wafer or a similar structure for dental works, such as the formation of dental prostheses or of support structures for dental prostheses, in particular for CNC numerical control centres or machines responsible for the formation of dental prostheses by removal of material; removing a predefined quantity of material, preferably according to a three-dimensional reference model, from the dental wafer to form, at least in part, a dental prosthesis or a support structure; the step of making the dental wafer comprising the steps of: overlapping at least two layers of formation, preferably a plurality of layers of formation, pre-imbued or to be imbued with at least one thermosetting resin or one thermoplastic resin, wherein at least one of the layers of formation comprises graphene and/or carbon fibre and/or glass fibre; compressing a layer of formation against the other to join these latter and break any micro air bubbles present therein; heating the layers of formation to harden these latter and form the dental wafer provided with graphene.
