Mouth cavity orthodontic planting body anchorage three-dimensional image navigation locating method and special equipment thereof

Abstract

The invention discloses a method for navigation and positioning of an implant anchorage in orthodontics based on three-dimensional imaging and a dedicated device thereof. The invention utilizes the existing three-dimensional navigation system for orthodontic implants to design a novel positioning device for implant anchorages. An infrared camera is used to emit or receive infrared rays to trace the position of an infrared reflection sphere on the positioning device for orthodontic implant anchorages, thereby determining the exact position of the device; and simultaneously signals are transmitted to a computer to display the position of the positioning device on a preoperative or intraoperative image data of a patient. Based on the software-aided comparison with the predetermined three-dimensional position of the positioning device before operation, the position of the positioning device is regulated by using a linked mechanical arm to meet the requirement of preoperative design. After locating in the desired position, the device can accurately implant the implant anchorage at the desired depth in the desired direction.

Description

1. Technical field [0001] The invention relates to a medical device, in particular to a three-dimensional image navigation and stereotaxic device for implant anchorage used in orthodontic treatment. 2. Background technology [0002] In orthodontic treatment, correct anchorage design, control and application are important factors to achieve good orthodontic effects. The anchorage technology based on the classic orthodontic concept in the square wire arch correction technology has played a key role in the development of various orthodontic correction technologies. [0003] The so-called "anchorage" is to keep the teeth that do not want to move during the correction process. At present, there are a variety of anchorage enhancement devices for orthodontists to choose clinically, but none of them can fully meet the requirement of anchorage teeth not moving. Therefore, in some cases of severe crowding or heavy deep coverage without loss of anchorage, the improvement of tooth ali...

Problems solved by technology

[0009] Aiming at the problems in the prior art, the present invention firstly discloses a three-dimensional image navigation and positioning method for orthodontic implant anchorage, which utilizes a medical CT machine to perform maxillary and maxillary Computed tomography scan of bone and dentition; three-dimensional image reconstruction of CT scan data of patient's upper and lower jaw and dentition by using implant anchorage navigation software before operation, so as to determine the implant site, direction, depth and surgical During the operation, the surgical space and the image space are combined by matching the anatomical marker points on the teeth adjacent to the surgical area with the corresponding marker points determined in the 3D reconstruction image; and then using the infrared camera lens Transmit or receive infrared rays, determine the specific position of the device by tracking the position of the infrared reflective ball on the orthodontic implant anchorage positioning device, and send the signal back to the computer, and then use the connected mechanical arm to adjust the orientation of the positioning device, so that It meets the preoperative design requirements
