Method for manufacturing metal frame for partial dental removable prosthesis of utilized in mouth of patient, involves machining preform completely and finally for obtaining frame based on computer data file converted into machining program

摘要

The method involves taking an impression of lower and/or upper jaws, and realizing a model of work. A scanner model is scanned to achieve a scanned file. A metal frame (1) is obtained from a standard preform (2A) or from outlines of geometry and volume according to a predetermined range of morphologies jaws at a disposal of an operator. The preform is completely and finally machined for obtaining the frame according to computer data file converted into a machining program by computer assisted manufacturing software and transmitted to a computer numerical control (CNC) machine tool. An independent claim is also included for a preform for final realization of a dental removable metal frame.
