Dental Prosthesis and Its Manufacturing Method
First Claim
1. A dental prosthesis, which includes holding parts for fixing an adjacent tooth a male member formed integrally with the holding parts, a female member formed integrally with an artificial tooth and having a slot to insert the male member thereto to thereby recover or promote a function of a damaged tooth, wherein the holding parts cover a part or the whole of the adjacent tooth to surround the adjacent tooth the holding parts are modeled on the original surface pattern of the adjacent tooth to provide the same surface pattern as the adjacent tooth whereby the holding parts can be fixed to the adjacent tooth with no or little grinding of the adjacent tooth.

Abstract
Disclosed herein are a dental prosthesis and its manufacturing method for restoring a lost tooth. The dental prosthesis has a male member formed on a holding part attached on an adjacent tooth for attaching an artificial tooth on the adjacent tooth and a female member formed in the artificial tooth so that the artificial tooth and the adjacent tooth can be connected with each other without grinding the adjacent tooth. The method for manufacturing the dental prosthesis includes the steps of duplicating an original model, waxing up the duplicated model, holding a sprue on the duplicated model in a state where the duplicated model is waxed up, and investing, burning out and casting the duplicating model.
