Estimating the term…
Digital design and/or fabrication of a dental prosthesis that includes a gingiva part having retention pockets and corresponding injection channels that extend from the retention pockets to an exterior of the gingiva part. The positioning of a matrix mated to a ball attachment of a dental implant is fixed in the retention pocket by injection of a curable adhesive through the injection channels and into the retention pockets. The location of the retention pockets and the injection channels may be automatically generated by a computer-aided design/computer-assisted manufacturing (CAD/CAM) system. The gingiva part including the retention pockets and injection channels can further be designed and fabricated by the CAD/CAM system.
A method for preparing a dental prosthesis, the method comprising:
A system for producing a dental prosthesis, the system comprising at least one processor operable to digitally design a gingiva part of the dental prosthesis, wherein the gingiva part is designed to include at least one retention pocket and at least one injection channel that extends from the retention pocket to an exterior of the gingiva part, the positioning of the retention pocket and the injection channel being automatically generated by the at least one processor.
A non-transitory computer-readable medium storing sequences of instructions, the sequences of instructions including instructions which, when executed by a computer system, cause the computer system to:
