Abstract

The invention discloses a positioning guide plate for removing unerupted supernumerary teeth in an anterior tooth area, and a manufacturing method thereof. A mucous membrane positioning guide plate and a boning positioning piece are detachably arranged, and can be conveniently used in a matching manner, a positioning ring for guiding the route of a boning device is arranged on the inner side surface of the boning positioning piece, the inner side surface of the positioning ring is a boning guide surface, and the boning guide surface is provided with a preset boning direction and the height ofthe positioning ring for guiding the boning depth of a machine needle. By means of the device, accurate incision positioning can be conducted on the unerupted supernumerary teeth, meanwhile, through the design of the positioning guide plate, the deboning area, depth and angle are accurately guided, incision and deboning are conducted in a small range, it is avoided that important permanent teeth and normal teeth are damaged due to positioning errors, and the supernumerary teeth are smoothly exposed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a positioning guide plate for extraction of embedded supernumerary teeth in the anterior region. Background technique [0002] Predicting the location of supernumerary teeth based on doctor’s experience is currently the main method for the extraction of embedded supernumerary teeth. The basic method is to use preoperative CBCT combined with the positioning of human anatomical landmarks. Incision was made, and the bone was removed through the preoperative preliminary anatomical landmarks to expose the embedded supernumerary teeth. In clinical operation, the biggest problem with this method is that it is impossible to accurately locate the depth and position of supernumerary teeth based on the doctor's experience judgment. However, the operation cannot completely avoid damage to the adjacent normal teeth, resulting in increased operation time and even damage to normal teeth may re...
