Surgical positioner for posterior tooth implantation hole preparation surgery and method of surgical locator

Abstract

The invention relates to a surgical positioner for a posterior tooth implantation hole preparation surgery, which is used for the posterior tooth implantation hole preparation surgery. The surgical positioner comprises a tooth implantation handpiece, a handpiece head, a drill bit and a positioner body, wherein the handpiece head is arranged at the front end of the tooth implantation handpiece, thedrill bit is connected to the handpiece head, the positioner is connected with the handpiece head; and the positioner comprises a tooth end, a handpiece end and cross rods, two ends of the cross rodsare respectively connected with the tooth end and the handpiece end, the handpiece end is connected with the handpiece head of the tooth implantation handpiece, and the tooth end is connected with the same tooth opposite to a surgery position. The handpiece head of the tooth implantation handpiece is connected with the same posterior tooth on the opposite side of the implant tooth by the surgicalpositioner, and the movement range of the drill bit on the handpiece head is controlled within a set range by setting the parameters of adjustors of the tooth end and the cross rods, so that the accuracy of the fossa during an implantation foramen preparation surgery is improved, and the reliability is better compared with that of bare-handed operations of doctors.

Description

technical field [0001] The invention belongs to the field of dental implant machine accessories, and is an auxiliary surgical instrument for guiding a dental implant mobile phone to precisely position a drill bit on an alveolar bone during hole preparation for posterior tooth implantation. Background technique [0002] Dental implant is a kind of missing tooth restoration method based on the lower structure implanted in bone tissue to support and retain the upper tooth restoration. It consists of two parts, the lower supporting implant and the upper dental restoration. It uses artificial materials (such as metal, ceramics, etc.) to make implants (generally similar to tooth roots), which are surgically implanted into tissues (usually the upper and lower jaws) and obtain firm retention support from bone tissue. Through special devices and way to connect and support the upper part of the dental restoration. Dental implants can achieve a restoration effect that is very similar...

Problems solved by technology

However, since the operation process is performed by doctors with bare hands, affected by the force direction, strength and reaction force, it is inevitable that there will be deviations between the angle of the drill bit and the expected angle, so that the long axis of the cavity is different from the long axis of the adjacent teeth. The included angle, that is, the inclination of the cavity, if the inclination is small, the angle foundation pile can be used to correct the effect without affecting the effect, and if the inclination is large, such as greater than 15 degrees, it will make it more difficult to make the upper restoration. The volume and weight of the restoration will also increase accordingly. In addition, when the tooth is stressed, the load direction has an included angle with the loading path of the implant. The axial force of the implant is not uniform, and the force direction is biased to one side for a long time. When the force is applied, the stimulation of the implant to the alveolar bone is inclined to the inclined side. There is a possibility of implant deviation in long-term use, which is not conducive to the long-term life and long-term effect of the implant.
