Bone plate penetration prevention device and method for tooth implant hole preparation

Abstract

The invention relates to a bone plate penetration prevention device for tooth implant hole preparation, and the device comprises a hand machine assembly and a safety assembly, wherein the safety assembly is arranged in the hand machine assembly and can connect or disconnect power transmission of a hand machine. According to the bone plate penetration prevention device for tooth implant hole preparation, the safety assembly that a poking piece and an electromagnet which are in mutual cooperation is ingeniously adopted, the upper limit of a drill torque can be flexibly set, when the drill torquereaches the set upper limit, a drill bit stops rotating, and sound and light signal reminding can be sent out at the same time. The situation that a bone plate is penetrated by a pioneer drill bit inthe tooth implantation hole preparation process, is simply and conveniently prevented, an implantation doctor is helped to control various operative complications, such as labial-buccal side or lingual-palate side bone plate lateral penetration, maxillary sinus penetration, mandibular nerve tube perforation, etc., and better safety experience is brought to a patient.

Description

technical field [0001] The invention belongs to the field of dental implant machines, and is a device for preventing a pioneer drill from penetrating a bone plate when preparing a hole for dental implantation. Background technique [0002] Dental implants have become one of the priority options for dentists and edentulous patients to restore missing dentition. By drilling holes in the jawbone, implants made of artificial materials (such as metals, ceramics, etc.) Dental implants can achieve a restoration effect that is very similar to natural teeth in terms of function, structure, and aesthetics. However, in the process of using a pioneer drill to drill holes in the jaw, side penetration of the lip-buccal or lingual-palatal bone plate may occur, and the bone plate of the maxillary sinus floor or the mandibular nerve canal may penetrate, resulting in secondary infection of the implant exposure. Increase the probability of implant failure and surgical accidents and complicat...

Problems solved by technology

However, due to the deformation error of the imaging system itself or the influence of magnification distortion or artifacts, there is a certain probability of error in the above methods, and various surgical complications such as maxillary sinus penetration and perforation of the mandibular nerve canal often occur in clinical practice, which brings great harm to patients. pain
