Abstract

The invention discloses an intraoral scanning rod for restoration of a dental post core or a post core crown. The intraoral scanning rod comprises a rod body that is arranged in a root groove of a tooth; and a core part that is arranged on the upper end of the rod body. The diameter of the core part is larger than the diameter of the rod body. The invention also discloses a method for manufacturing the intraoral scanning rod used for restoration of dental post core or post core crown, and the method comprises steps of scanning a drill to obtain 3D data and then applying the 3D data in manufacturing with cutting technology. Namely, the digital technology is applied in dental restoration to solve the casting defects that is difficult to resolve in traditional casting technology, and also solve the limitation that some materials can only be processed by casting technology.

Description

Technical field [0001] The present invention relates to the technical field of clinical tooth restoration treatment, more specifically, the present invention relates to an intraoral scanning rod for dental post core or post core crown restoration and a manufacturing method thereof. Background technique [0002] The existing dental post core and post core crown restoration technologies use traditional casting methods or semi-finished products on the market. In traditional casting technology, the production cycle is long and the production process is complicated; the finished post and core sold on the market have a single material and a single shape, which is difficult to meet the individual needs of patients. [0003] Therefore, it is necessary to provide an intraoral scanning rod for dental post core or post core crown restoration to at least partially solve the problems in the prior art. Summary of the invention [0004] In the summary of the invention, a series of simplified conc...
