The correct term for palatal wisdom teeth should be maxillary wisdom teeth, and the steps for removing maxillary wisdom teeth are anesthesia, incision flap, debridement, splitting the wisdom teeth, extracting the wisdom teeth, treating the extraction sockets, and suturing. The details are as follows. 1. Anesthesia: generally choose the upper postalveolar nerve block anesthesia. 2. Incision and flap: Because of the limited field of view for the operation of removing maxillary wisdom teeth, it is usually necessary to incise and flap to provide a clear surgical field of view. 3. Bone removal: the bone removal site and the amount of bone removal are decided according to the bone coverage condition, and the maximum circumference of the crown is revealed in principle. 4. Splitting of wisdom teeth: to relieve the resistance of neighboring teeth through crown amputation and root splitting, and to reduce the bone resistance at the root. 5. Wisdom tooth extraction: Choose the appropriate tooth extractor and extract the split parts. 6. Treatment of extraction sockets: cleaning the extraction sockets with saline, compression to reset the enlarged sockets, and trimming the sharp bone edges. 7. Suture: reset and suture the tissue flap to facilitate healing, prevent postoperative bleeding and protect the blood clot.
