The process of wisdom tooth extraction is divided into several steps, such as preoperative analysis, anesthesia, removal of resistance, loose extraction, wound closure, etc. The specific operation should be based on the attending doctor. 1. Pre-operative analysis: clinically, due to the difficulty of removing wisdom teeth growing horizontally, a panoramic film or CBCT should first be taken before starting the extraction process, which will be analyzed by a professional dentist, who will determine the extraction plan and then sign an informed consent form. 2. Anesthesia: Before starting wisdom tooth extraction, we should also use iodophor solution to locally disinfect the area where the needle is inserted, and then extract 1-2 ml of blue marijuana for local infiltration anesthesia or block anesthesia. 3. Removal of resistance: After making sure that the anesthesia works, the gums need to be incised to expose the tooth, and then the crown as well as the alveolar bone will be removed by using the ultrasonic bone cutter or high-speed turbine handpiece to remove the resistance. 4. Loosening and extraction: After removing the resistance and determining whether the transverse wisdom tooth has enough space to dislocate, the tooth is loosened and extracted using extraction forceps. 5. Wound closure: After checking with a spatula to make sure that there are no residual roots or bone fragments left in the socket, the gums of the incision will be closed without tension using special dental sutures. The above description is the basic process of wisdom teeth extraction, the specific operation needs to go to a professional dental hospital to find a doctor to carry out the treatment.
