Oral implantation method for improving jaw bearing mode and screw implant

Abstract

The invention discloses an oral implantation method for improving a jaw bearing mode and a screw implant. A spring-shaped screw with internal and external threads is made of pure titanium or titanium alloy with a diamond section; and the screw consists of a cortical bone section with fine threads and a cancellous bone section with coarse threads, and is arranged in a jaw spare hole in a compressed state, so that prestretching stress is formed in a bone tissue. A matrix is a cylindrical external thread main body, and is separated into a gum penetration section, a fine thread section, a coarse thread section and a guide section from top to bottom, and the center of the matrix is a composite cavity; external threads of the fine thread section and the coarse thread section are matched with internal threads of the cortical bone section and the cancellous bone section to form threaded connection; and the guide section is a one-third segment, and the bottom of the guide section is provided with a crossed groove. By the invention, the conventional integrated implant is optimized into a composite implant that the screw and the matrix are matched, the invention has the advantages of reliable connection and low possibility of loosening, the stress level of the alveolar ridge crest can be reduced, chewing impact can be relieved, and jaw damage and absorption can be effectively prevented.

Description

technical field [0001] The invention relates to a screw sleeve type oral implant for improving the bearing mode of the jaw, which belongs to the field of intraosseous implants. Background technique [0002] my country is a country with a large population, but there is a lack of awareness about oral hygiene knowledge, and the awareness of oral health care is not strong. At present, my country has become a high-incidence area for oral diseases. According to the third national oral health epidemiological survey completed in 2006, the middle-aged and elderly people have severe tooth loss. of the elderly are edentulous. At present, there are three common methods of restoring missing teeth in oral clinic: removable dentures, fixed dentures and dental implants. Removable dentures are attached to the adjacent teeth of the missing tooth by using a retention mechanism, which has the characteristics of free removal and easy cleaning; however, the retention and aesthetics are poor, af...

Problems solved by technology

[0005] In order to overcome the phenomenon of stress concentration on the crest of the alveolar bone caused by the existing implants under the masticatory force, and to improve the stability of the implants during the healing process and the replaceability of the damaged implants, this paper invented a An oral implant method that can effectively improve the stress distribution in the jawbone after the oral implant is loaded, and a screw-type implant
