A kind of complete denture and preparation method thereof

Abstract

The invention relates to a complete denture and a preparation method thereof, which belongs to the technical field of oral repairing. The denture comprises a foundation support and artificial teeth; the foundation support of maxillary artificial teeth comprises an upper alveolar crest top area and an alveolar crest side area, the artificial teeth are arranged on the foundation support of the upperalveolar crest top area, and the alveolar crest side area is disposed in an a curved area of the upper alveolar crest top area; a foundation support portion, facing the front side of the oral cavity,of the outer portion of the upper alveolar crest top area is made of silicone rubber; the foundation support of the underjaw artificial teeth comprises a lower alveolar crest top area and a retromolar pad area, the artificial teeth are arranged on the foundation support of the lower alveolar crest top area, and the retromolar pad area is disposed on an end of a curve of the lower alveolar crest top area; and the foundation support portion, facing the front side of the oral cavity, of the outer portion of the lower alveolar crest top area is made of silicone rubber, and the end of the retromolar pad area is made of silicone rubber. The soft silicone rubber on the edge of a specific portion can increase the fixation force, so that a repairing opportunity can be provided for a patient with apoor alveolar crest condition.

Description

technical field [0001] The invention relates to a novel complete denture and a preparation method thereof, belonging to the technical field of oral restoration. Background technique [0002] The edentulous jaw refers to the jaw bone after the complete loss of the upper jaw or (and) the lower jaw dentition due to various reasons. The edentulous upper and lower jaws can be divided into three parts: alveolar ridge, oral vestibule, and oral cavity. Dentition loss is a common and frequently-occurring disease of the oral cavity, which is more common in the elderly. Patients with missing teeth lose their ability to cut and grind food, affecting digestion, as well as speech, facial appearance, and the neuromuscular system. For edentulous patients, common restoration methods include complete dentures and implant dentures. Complete dentures are widely used because of their low price. [0003] A complete denture is a restoration that uses artificial materials to replace the missing ...

AI Technical Summary

Problems solved by technology

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

[0006] The Chinese patent document (Application No. 201610077213.3) is a method of using a new type of edge plastic material to make a closed impression of a complete denture. The accuracy of the edge of the impression is improved when taking the impression and pouring the impression, but the material of the complete denture base is still the traditional hard polymethyl methacrylate, so when the patient is yawning, sneezing, Actions such as coughing will still destroy the edge closure of the denture, and the retention will drop. The denture will fall off. This solution does not improve the denture retention caused by the slight dislocation during the use of the complete denture.
