Abstract

The invention discloses a double-root combined implant and an implant method, belongs to the technical field of dental implants, and aims to increase the lateral allowance of implanted alveolar bone and reduce the risk that the alveolar bone at a molar position is damaged and broken due to lateral stress by combining a large implant and a small implant to approach a double-root structure of a simulated natural molar. Meanwhile, one screw is added to fix the two implants, the large implant and the small implant are provided with two fixing screw holes, an abutment and the dental crown which are matched with each other on the large implant and the small implant can be fixed through two central screws, and the stability of the abutment and the dental crown on the implants is improved. The risk that a single central screw is easy to break due to complex load is also reduced, an anti-rotation structure which needs to be independently arranged for the abutment and the implant can also be omitted, the processing steps are reduced, and the application range is wider.

Description

technical field [0001] The invention belongs to the technical field of dental implants, and relates to a dental double-root combined implant and an implantation method. Background technique [0002] Nowadays, the development of dental implants has gradually matured, and clinical applications have become very common. Therefore, research on dental implants is also a hot spot in the research and development of various units. The most important features of dental implants are their performance close to natural teeth, high stability, and good aesthetic performance. Nowadays, our requirements for dental implants are getting higher and higher, and at the same time, research on its various components is also in-depth improvement. We also have better expectations for the performance requirements of dental implants, such as how to improve the mechanical properties of implants in the bone, and how to improve the stability of the central screw of the implant. Most of the implants in ...
