Mucoperiosteal type implant

Abstract

The invention discloses a mucoperiosteal type implant, which comprises a pure titanium casing matched with the skeleton face of a covered synostosis oral cavity. The longitudinal section of the casing in the extending direction is saddle-shaped, and a gap between the longitudinal section of the casing and covered bones can be filled with materials favorable to guiding of skeletal regeneration. A plurality of papillary concave portions and convex portions are respectively arranged on the edge of the casing, the concave portions and the convex portions are arranged at intervals, and the edge form is apt to enable mucoperiosteal tissue to be implanted and filled. At least two fixing holes and fixing screws matched with the fixing holes are arranged on the casing, the material of the fixing bolts is pure titanium, and the design of the casing with a rough inner surface and a smooth outer surface is favorable to osseointegration and protection of soft tissue. A connecting structure connected with false teeth or artificial crowns to be repaired is arranged outside the sellar crest portion of the casing to be in mechanical connection or cementation with the false teeth or the artificial crowns so as to improve repairing effects.

Description

Technical field

[0001] The invention relates to a medical implant, in particular to a mucoperiosteal implant that replaces the mucoperiosteal and directly covers the bony surface of the bony oral cavity. Background technique

[0002] The bony oral cavity (cavitas oris) is surrounded by the upper jaw, jaw bone, and mandible. The roof of the bony oral cavity is the bony palate, and the anterior and side walls are surrounded by the alveolar bones and teeth of the upper and lower jaws. Among them, teeth are an indispensable tool for people to eat. According to different divisions of labor, they have the functions of cutting, shredding and grinding food. The loss of teeth will cause decreased chewing function, digestive system disorders, and affect appearance and pronunciation. Alveolar bone is the part of the jaw bone that surrounds and supports the tooth root and is closely connected to the tooth root by the periodontal ligament. It undergoes progressive and irreversible absorptio...
