Problems solved by technology

[0003] For the oral positioner in the related art, in order to facilitate installation and disassembly, the positioning ball and / or the infrared reflective ball are first installed on the corresponding bracket, and then the bracket is installed on the body of the oral positioner. Since the bracket is installed on the body There are inevitably installation errors, resulting in errors in the positional relationship between the positioning ball and the infrared reflective ball, resulting in an inaccurate matching relationship between the coordinate system determined by the positioning ball and the coordinate system determined by the infrared reflective ball. Navigation accuracy during surgery

Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0048] Before dental implant surgery, patients are usually required to take three-dimensional medical images of the oral cavity, such as cone beam computed tomography (CBCT) images, to obtain the position and status of the site to be operated. In order to realize the real-time navigation during the surgery of the dental implant robot system, so that the mobile phone can accurately and efficiently reach the site to be operated, it is necessary to match t...

Abstract

The invention provides an oral cavity positioner, which includes a bracket, a clamp, a positioning ball and an infrared reflective ball. The connecting part of the fixed part and the positioning part; the clamp is arranged on the fixed part, including a fixed arm, a clamping arm, an adjusting arm and a set screw, and the clamping arm is rotatably installed on the fixed part, and is used to approach the fixed arm by turning Clamp molars or dental arches; the adjusting arm is connected with the clamping arm, and the adjusting arm is provided with a threaded hole; the set screw is threaded on the threaded hole, and one end of the set screw passes through the threaded hole to abut against the fixed part, It is used to drive the clamping arm to rotate by screwing in or out of the set screw; the positioning ball is installed on the fixed part to determine the relationship between the three-dimensional medical image coordinate system and the oral positioner coordinate system; the infrared reflective ball is installed on the positioning part , used to determine the position of the oral locator coordinate system in space.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of dental implants, in particular to an oral positioner and a dental implant robot system. Background technique [0002] During dental implant surgery, it is necessary to wear an oral locator in the oral cavity to realize real-time navigation during the surgery. [0003] For the oral positioner in the related art, in order to facilitate installation and disassembly, the positioning ball and / or the infrared reflective ball are first installed on the corresponding bracket, and then the bracket is installed on the body of the oral positioner. Since the bracket is installed on the body There are inevitably installation errors, resulting in errors in the positional relationship between the positioning ball and the infrared reflective ball, resulting in an inaccurate matching relationship between the coordinate system determined by the positioning ball and the coordinate system determined by ...
