Minimally invasive techniques have become one of the most popular topics in modern surgical procedures. The application of minimally invasive techniques not only reduces the trauma of patients, but also facilitates the recovery of diseases. It can effectively eliminate the trauma caused by the surgery. Dental and alveolar surgery is a part of oral and maxillofacial surgery, and it is the foundation of maxillofacial surgery. Due to its special surgical site, the extraction technique is no less fearful and harmful to patients than other surgical procedures, especially when the surgeon holds the traditional extraction (similar to chisel, pliers, hammer), which is a big challenge to patients’ psychological tolerance. Therefore. The minimally invasive technique of tooth extraction has opened a new era of tooth extraction, making the ancient surgical history of tooth extraction more standardized, minimally invasive, comfortable and personalized. With the popularization of the concept of minimally invasive extraction, not only the efficiency of surgery is greatly improved, but also the operation time is shortened. It not only reduces the fear and pain of patients, but also reduces the occurrence of common complications, especially serious complications. The current minimally invasive surgical extraction technique is to remove the bone tissue, divide the tooth street and remove the obstructed wisdom teeth and other difficult teeth in a state of basic painlessness. This method causes little damage to the surrounding tissues and has a mild postoperative reaction. In clinical practice, its minimally invasive nature and advantages are mainly manifested in the following aspects No intraoperative violence, less fear of patients The traditional method of hammering and splitting crowns and debriding bone is used. There is a certain degree of discretion, sometimes causing accidental injury, while the strong vibration will affect the health of the adjacent tissues, such as the award of the jaw joint, patient consultation easy to produce cattle. Fear? Minimally invasive tooth extraction surgery completely rejects the traditional methods of bone removal and gap enlargement, and applies the microdynamic technology, which does not use knocking or chiseling. A special high-speed impact drill is used to gently remove the surrounding bone. The bone around the affected tooth is removed with little vibration, and the affected tooth is easily extracted, reducing the patient’s psychological fear and physiological damage. Less surgical trauma reduces bone removal and increases dental tissue cutting. Due to the strong ability of the impacted pneumatic handpiece to cut the tooth, the bone can be removed accurately as needed, the direction and range of cutting can be easily and precisely regulated, and the tooth can be divided at will in all parts of the tooth. The resistance can be removed accurately. The range of debridement is not only controllable, but also the purpose. In most cases, only the bone of the compartment surface and a little bone of the buccal side of the blocked tooth are removed to form the groove, which avoids the reduction of the height of the alveolar process and facilitates the later implant restoration. Reduce mechanical damage.
