Abstract
A dental or medical device for use in construction of a finished dental or medical appliance which includes a shapable prepreg, where the prepreg coontains fibers, and at least one solid body attached to the prepreg. The solid body attached to the prepreg constitutes a solid body included in the finished appliance and forms a part or whole of the outer surface of the finished appliance. Also disclosed are methods for the manufacture of the device, either so that the prefabricated solid body is contacted with the prepreg, or so that the solid body is created simultaneously with the manufacturing of the device.
Claims21
A dental or medical device for use in construction of a finished dental or medical appliance, said device comprising a shapable prepreg, wherein said prepreg comprises fibers, and at least one solid body attached to said prepreg, wherein said solid body constitutes a solid body included in the finished appliance and forms a part or whole of the outer surface of said finished appliance.
Method for the manufacturing of a dental or medical device for use in construction of a finished dental or medical appliance, wherein said device comprises a shapable prepreg comprising fibers and a resinous matrix comprising a polymerizable monomer, a polymerizable dendrimer, or a combination thereof, and at least one solid body attached to said prepreg, wherein said solid body constitutes a solid body included in the finished appliance, said method comprising the steps of
- contacting the solid body with the prepreg, and
- optionally protecting the bottom surface of the prepreg with a protecting tape.
Method for the manufacturing of a dental or medical device for use in construction of a finished dental or medical appliance, wherein said device comprises a shapable prepreg comprising fibers, and at least one solid body attached to said prepreg, wherein said solid body constitutes a solid body in the finished appliance, said method comprising the steps of
- adding a mixture of fillers and an uncured resin into an impression formed in a mould, said impression having the shape and size of the solid body to be created,
- pressing the fibers against the mould so that the fibers partly penetrate into the mixture in the impression,
- curing at least partially the mixture in the impression to create the solid body, and
- optionally adding a monomer liquid mixture to the fibers to create the final prepreg.
