Expansive orthodontic anchorage implant

Abstract

The invention belongs to medical apparatus, and in particular relates to an expansive orthodontic anchorage implant, which is characterized in that the anchorage implant comprises an implant and an expansive body matched with the implant; the upper end of the implant is a neck shoulder; the lower end of the implant is an implant body; the outer diameter of the neck shoulder is greater than that of the implant body; the neck shoulder is provided with an internal thread by taking a central axis as a center; the lower end of the internal thread is provided with an inner hole; the lower end of the inner hole is connected to a symmetrical gap through a tapering transition hole; the upper end of the expansive body is a hexagonal-structure nut; the lower end of the hexagonal-structure nut is an expansive-body neck thread; the size of the expansive-body neck thread is matched with the internal thread; the lower end of the expansive-body neck thread is provided with a column body matched with the inner hole; the lower end of the column body is a cone; and the shape of the cone is slightly smaller than the tapering transition hole of the gap. The anchorage implant has the advantages of utilizing mechanical expansion to increase the angulation angle of the contact surface of the tail end of the implant and bone tissue, compressing surrounding bone tissue at the same time, greatly increasing the holding force of the implant and reducing the loosening rate of the implant.

Description

technical field [0001] The invention belongs to medical equipment, in particular to an expanded orthodontic anchorage implant. Background technique [0002] Orthodontic treatment is the process of applying force to the teeth or jaws and making them reach a certain position. When applying force to the teeth and jaws, the reaction force of the force must be borne by a stable device, which is the so-called "orthodontics". resistance" concept. Orthodontic anchorage implants mainly include: prosthetic implants, palatal implants, retromolar implants, micro titanium plates, micro titanium nails and many other bony anchorages. Orthodontic anchorage implants can achieve the type of tooth movement that is difficult to achieve with traditional orthodontic methods, which also affects the design and implementation of orthodontic treatment to some extent. The implant anchorage system also changes from traditional prosthetic implants to specially designed orthodontic anchorage implant sy...

AI Technical Summary

Problems solved by technology

However, clinically, it is common that bone quality defects (such as osteoporosis) affect the early stability of orthodontic anchorage implants, causing implant loosening and falling off, resulting in failure of orthodontic treatment.
