Full denture and preparation method thereof

Abstract

The invention discloses a full denture and a preparation method thereof. The full denture comprises a lower denture assembly which comprises a lower base support, wherein lower dentures are embedded at the top part of the lower base support; a lower fitting groove matched with an alveolar ridge is arranged at the bottom part of the lower base support; and a weighting part is arranged in the lowerbase support. The full denture provided by the invention has the following advantages: the lower fitting groove matched with the alveolar ridge is arranged at the bottom part of the lower base support, and the base support can be tightly attached to the mucosa of the alveolar ridge, so the full denture has good position fixing performance; meanwhile, the weighting part is arranged in the lower base support to increase the weight of the lower base support and reinforce the adhesive force and the sealing performance of the base support, so the position fixing performance of the full denture is greatly improved; and the lower base support of the full denture is tightly and firmly combined with the alveolar ridge, so the full denture is not easy to loosen, fall off and float upwards, is comfortable for a user to wear, and has wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of oral restoration, and in particular relates to a complete denture and a preparation method thereof. Background technique [0002] There are many cases of tooth loss in the oral cavity due to periodontal disease or other factors, and the incidence rate is generally proportional to age, that is, the proportion of tooth loss is higher in the elderly. Complete dentures are a routine restoration treatment for edentulous patients. Due to the improvement of living standards, people often eat all kinds of things that are not good for teeth, so many people will lose most of their teeth when they get older. It has brought great inconvenience to these patients. Full dentures are removable denture restorations that use artificial materials to replace the missing complete dentition and related tissues of the upper jaw or lower jaw. For patients who have completely lost their teeth, the doctor will make a complete den...

AI Technical Summary

Problems solved by technology

Only by keeping the complete dentures retained and stable in the mouth of edentulous patients can the patient's mastication, pronunciation function and aesthetics be effectively restored, and sufficient retention is the premise and basis for the stability of complete dentures. Dentures that are out of place won't stay stable

[0004] The retention effect of traditional full dentures is not good, and it is prone to slight dislocation during use, which destroys the edge seal around the dentures, and immediately reduces the retention force of the full dentures significantly.

When the patient opens his mouth wide, yawns, sneezes, coughs, or sticks out his tongue, the edge seal will be damaged, the dentures will be slightly loose, the overall adsorption effect will be significantly weakened, the retention force will be greatly reduced, and the dentures will be completely dislocated. It makes patients feel inconvenient to use, especially for patients with more alveolar ridge absorption and less fullness. Therefore, traditional complete dentures cannot provide good retention. It is very important to design a complete denture with better retention performance. Necessary
