Problems solved by technology

However, there are still some problems in the long-term success rate of implant dentures. For example, with the prolongation of observation time, implants will loosen and break after denture implantation, which will lead to the failure of implant restoration surgery.
According to clinical observations, the main causes of implant loosening and fracture are the unreasonable design of the implant, the low strength of the neck, and the difficulty of osseointegration caused by bacteria and microorganisms easily entering the cortical bone during the implant operation. failure, resulting in loosening of the implant

Abstract

The micro thread implant includes one conic top with larger upper part and smaller lower part, one conic hole including one octagonal middle part and one lower screw hole part and surface coating of hydroxyapatite. It features the neck with fine thread, the root part with self-tapping straight thread and the conic end, with both the fine thread and the straight thread being saw tooth threads. Thepresent invention has high neck strength, capacity of preventing microbes from invading, easy integrating with bone, easy screwing into the jaw bone and self locking, and may be used in repair dentaldefection, especially false tooth implanting operation.

Description

A microthread implant technical field The invention relates to a medical device, in particular to a micro-thread implant with biological sealing function for full-jaw implant dentures. Background technique Dental Implantology is a cross-industry medical technology developed in the 1960s. It is a comprehensive technical discipline involving medicine, electronics, machinery, materials and biomechanics. Implant dentures are an important part of dental implantology. Implant dentures are widely used in the restoration of dentition defect and loss, especially the application of full jaw implant dentures, which solve some problems that cannot be solved by conventional denture restoration for patients with severe alveolar ridge absorption. However, there are still some problems in the long-term success rate of implant dentures. For example, as the observation time prolongs, the implants will loosen and break after denture implantation, which will lead to the failure of implant re...
