Semi-finished complete denture and production method

Abstract

The invention discloses a semi-finished complete denture, which comprises an upper jaw and a lower jaw, wherein both the upper and the lower jaws consist of false teeth and bases, wherein the thickness of the base is 0.5-0.8mm, and a machining allowance of about 2mm is arranged along the extending direction of the edge of the base. Because the thickness of the base is only 0.5-0.8mm, a base mucous membrane tissue surface is not formed, enough space is left between the mucous membrane tissue surface and the corresponding part of an alveolar ridge to be suitable for alveolar ridges of various shapes, and a pad is additionally added so that the semi-finished complete denture can be suitable for different patients; and the base edge is provided with the machining allowance of about 2mm, so the denture is suitable for a doctor to grind the excessive base tissue when the doctor adjusts and grinds in the oral cavity of the patient after the comparison. By utilizing the semi-finished complete denture to make the complete denture, the invention has less procedures, short time and good quality. Moreover, the invention further provides a method for producing the semi-finished complete denture.

Description

technical field [0001] The invention relates to a denture, in particular to a semi-finished complete denture for processing into a complete denture. The invention also relates to a method for manufacturing the semi-finished complete denture. Background technique [0002] Complete dentures are a relatively complicated subject in oral restoration. The production process of complete dentures is relatively complicated. Traditional complete dentures require 13 steps to take impressions (one time, two times) ), pouring models, making wax-ups, making jaw embankments, seeking jaw relationships, maxillary frames, arranging teeth, carving wax, blowing light, packing boxes, removing wax and filling glue, heating, opening boxes and polishing. The process requirements are high and the technology is difficult. [0003] Now there are denture technicians who can make finished dentures for doctors. This does reduce the work of doctors, but it also leaves disadvantages for doctors and patie...

AI Technical Summary

Problems solved by technology

[0003] Now there are denture technicians who can make finished dentures for doctors. This does reduce the work of doctors, but it also leaves disadvantages for doctors and patients. Our current technicians have almost never been to clinics, and patients’ oral and facial shapes are changeable. Yes, but the communication between the doctor and the technician is prone to deviations. On the way to the processing factory, the model is prone to breakage, vertical distance changes, and jaw relationship changes. The teeth produced in this way will also change and need to be adjusted. Rework, at this time, the teeth in the patient's mouth no longer have the shape of the teeth, and the height is not 1 / 2 of the original. The so-called cusps are facing each other and become flat contact, resulting in a long cycle and difficult to guarantee the quality of the denture.
