Abstract

The invention discloses a positioning guide plate for extraction of embedded supernumerary teeth in the anterior tooth area and a manufacturing method. By detachably setting the mucosal positioning guide plate and the bone removal positioning piece, they can be used together more conveniently. In the bone removal positioning piece The side is provided with a positioning ring for guiding the route of the bone removal device. The inner side of the positioning ring is a bone removal guide surface. The bone removal guide surface is set with a predetermined bone removal direction and the height of the positioning ring to guide the bone removal depth of the bur. The present invention can perform accurate incision and positioning on the embedded supernumerary teeth, and at the same time, through the design of the device, it can precisely guide the area, depth and angle of bone removal, incision and bone removal in a small range, and avoid damage to important permanent teeth and normal teeth due to wrong positioning. Teeth, supernumerary teeth are smoothly exposed.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a positioning guide plate used for the extraction of impacted supernumerary teeth in anterior teeth area. Background technique [0002] Predicting the position of supernumerary teeth based on the experience of doctors is the main method for extraction of supernumerary teeth at present. The basic method is to use preoperative CBCT combined with the positioning of human anatomical landmarks. The incision was made, and the bone was removed through the preoperative preliminary anatomical landmarks to expose the impacted supernumerary teeth. In clinical operations, the biggest problem with this method is that the depth and position of the supernumerary teeth cannot be accurately located based on the experience of the doctor, which is mainly manifested in the following aspects: there are normal teeth around the supernumerary teeth, and due to the lack of a guiding positioning device ...
