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
The present invention relates to a kind of medical implantation body, particularly relate to a kind of alternative mucoperiosteum, directly be covered in the Mucoperiosteal type implant of bone oral cavity surface of bone.
Background technology
(cavitas oris) surrounded by upper jaw bone, jawbone and mandibular bone in the bone oral cavity.The top in bone oral cavity is the bone palate, and antetheca and sidewall are surrounded by alveolar bone and the tooth of upper and lower jawbone.Wherein, tooth is people's requisite instruments of eating, the function that cutting is arranged, tear up and grind food according to the difference division of labor.And can cause after loss of tooth, masticatory function descends, the digestive system illness, affects appearance and pronunciation simultaneously.Alveolar bone is that jawbone holds and the part of supporting that root of the tooth, mat periodontal membrane closely are connected with root of the tooth, and progressive irreversible absorption occurs after loss of tooth for it.Adopt clinically artificial tooth to repair the natural tooth of disappearance.Wherein, implant denture is considered to repair the preferred manner of agomphosis.The related implantation body of implant denture can be divided into endosteal implant, subperiosteal implant, endodontic implant and wear bone implantation body according to the implant site classification at present.There is strict demand in above-mentioned implantation body to height and the width of implanting the bed bone, is not suitable for the case that the serious atrophy of alveolar bone absorbs.The research that the gum structure is worn by relevant implantation body shows, when the peri-implant soft tissue thickness, within the specific limits the time, the barrier action with opposing inflammation, can obtain the surrounding soft tissue situation similar to the natural health tooth.The research of relevant guided tissue regeneration and guided bone regeneration shows, enter the bone defective region by biomembrane as the barrier action of titanium film stops connective tissue and epithelial tissue, be used in conjunction with some factor that is conducive to skeletonization and can guide the osteanagenesis of bone defective region as bone morphogenetic protein(BMP), ENAMELIN EMD.
Summary of the invention
The purpose of this invention is to provide a kind of Mucoperiosteal type implant, can directly cover the implantation body of bone oral cavity surface of bone, so that for artificial tooth, artificial crown or prosthesis provides support, maintenance, the stable and pedestal be connected with osseous tissue.
