Abstract

The invention relates to a root-end surgery guide plate. A guide plate body includes a tooth surface part matched with a clinical dental crown and a bone surface part matched with an alveolar bone. The tooth surface part includes a snapping surface part matched with a snapping surface of the clinical dental crown, a tongue surface part and a lip surface part. The tongue surface part and the lip surface part are disposed on the two sides of the snapping surface part and matched with a tongue surface and a lip surface of the clinical dental crown respectively. The snapping surface part is provided with a retention indicating window. The bone surface part is provided with a guide plate positioning hole matched with a root-end surgery instrument, and the upper edge and the lower edge of the guide plate positioning hole are located at the 1-4 mm position and the 1-3 mm position above and below root-ends of tooth roots of offending teeth respectively. According to the root-end surgery guideplate, on the one hand, the fitness of the guide plate and a tooth jaw is judged, and operation accuracy is improved; on the other hand, the operation position, angle and direction in a root-end surgery can be precisely positioned through the guide plate positioning hole, and a root-end in a lesion area is removed precisely.

Description

technical field [0001] The invention belongs to the field of oral medical instruments, and more specifically relates to a guide plate for root tip surgery. Background technique [0002] Root canal therapy is the first choice for the treatment of pulp disease and periapical disease, and can solve most of its problems. However, due to the complexity of root canal anatomy, there are still limitations in clinical diagnosis and operation techniques. Studies have pointed out that after strict mechanical preparation, chemical disinfection and strict filling of the root canal according to the basic principles, the treatment success rate will be 87% to 92%. The remaining 8% to 13% require root canal surgery, the most common of which is apical surgery. [0003] The steps of apical surgery include: incision and flap, bone removal and window opening, periapical scaling, apexectomy, exploration, root canal retrograde preparation, root canal retrograde filling, and suture. The difficult...
