In recent years with the development of dentistry reserved for dentistry, the indications for tooth extraction in alveolar surgery have been relatively narrowed. However, in some cases, tooth extraction is still an effective way to cure the disease and is the most widely used and basic therapeutic surgery in oral and maxillofacial surgery. Due to the complexity of oral anatomy and limited operating space, the surgical process will inevitably cause different degrees of damage to the soft and hard tissues in the surgical area, and may also cause a certain degree of systemic reaction or certain complications. In addition, most of the extracted teeth, except for blocked teeth and supernumerary teeth, need to be considered for phase II restorative treatment in order to re-establish occlusal function, but the patient’s satisfaction of the restorative treatment design is based on the good condition of the remaining alveolar ridge. There is an irreversible, progressive resorption process of the alveolar ridge after tooth extraction. The healing process of the alveolar socket itself is manifested by the formation of new bone within the socket and the loss of the external alveolar ridge {degree and width. The loss of the height and width of the alveolar ridge brings the problem of insufficient alveolar bone for future restoration and implant treatment, which becomes one of the common clinical difficulties. Therefore, the alveolar surgeon should not only master the extraction operation technique, but should also have a holistic vision, systematic thinking and minimally invasive concepts. In terms of tooth extraction operations must consider the following two aspects of the problem: First, the problem of creating conditions for two-stage restoration after tooth extraction. This is mainly reflected in two aspects, one is the adequate amount of bone to reduce the difficulty of implant surgery, avoiding the second bone grafting, reducing the cost of treatment, shortening the treatment time; secondly, if you can maintain the original alveolar ridge height, width, and soft tissues, including the gingival margin position as well as the gingival papilla height, it is possible to get a more satisfactory aesthetic restoration effect, while also avoiding the second phase of the complex tissue incremental processing. Maxillofacial surgeons must consider this issue before the extraction operation and maximize the conditions for phase II restoration. Minimally invasive techniques and operations are one of the effective ways to do this. Secondly, the problem of trauma control in alveolar surgery. Any invasive operation is accompanied by a certain degree of tissue trauma reaction, which is the body’s normal healing process. However, severe trauma and adverse reactions or complications can significantly reduce postoperative quality of life (QoL) and affect the social life of patients. Since the beginning of surgery, surgeons have sought to minimize trauma to their patients, not only tissue and organ wise, but also physiologically and psychologically. In order to reduce surgical trauma, thereby reducing the stress brought about by surgery, and minimizing the recovery time of the patient after surgery, these are the eternal pursuit of surgical treatment.At the end of the twentieth century, the surgical community appeared in the “minimally invasive surgery” (minimallyinvasive surgery, MIS) a new concept. After nearly 20 years of clinical practice, the concept of MIS has been generally accepted by surgeons and is considered to be the main theme of surgical development in the 21st century. The concept of Minimally Invasive Surgery (MIS) is to provide “humane and humanistic” medical services to minimize the physical and psychological trauma of patients. As the concept of “minimally invasive” continues to penetrate into the field of surgery in recent years, it has brought about a great change in traditional surgical thinking, and the field of alveolar surgery has also begun to gradually advocate the “minimally invasive” mode of operation. However, compared with the minimally invasive surgery of general surgery, cardiothoracic surgery, gynecology and other oncology, which is widely used in general surgery, cardiothoracic surgery, and gynecology, and which is based on laparoscopic surgery, and tends to use the body’s natural cavities, the maxillofacial region does not have a similar anatomical structure. Therefore, minimally invasive surgical treatment of oral and maxillofacial alveolar surgery needs to form a style adapted to its own anatomical characteristics. It should be recognized that the concept of “minimally invasive” exists and develops in comparison, and with the emergence of new theories and technologies, minimally invasive techniques will inevitably be followed by the conceptual and formal advancement. For example, after the birth and clinical use of high-speed turbines, high-speed turbine technology is a minimally invasive technique for traditional alveolar surgery, but it also has certain limitations, such as bone burns, emphysema, soft tissue damage. The emergence of ultrasonic bone knife again gave the concept of micro-innovation. The application of Er laser in alveolar surgery is considered as a new technique to realize minimally invasive alveolar surgery. “Minimally invasive” is to minimize tissue trauma, preserve tissue, and achieve therapeutic results through the application of new instruments and methods. At the same time, it allows the patient to achieve the fastest recovery and the least cost, realizing the best cost-effectiveness ratio. However, the minimally invasive concept based on small incision and small trauma does not mean poor exposure of the surgical field, increased operating time, low efficiency and slow recovery. This is because it actually deviates from the original intent of minimally invasive surgery. The basic operating techniques of alveolar surgery and modern technological operations can only be complementary, not mutually exclusive. The concepts of traditional surgery and minimally invasive surgery also need to be dialectically unified and not opposed to each other. Tooth extraction, as the final treatment for certain dental diseases, is inevitably accompanied by a certain degree of trauma. In fact, the extraction of the affected tooth is the starting point for the restoration of the tooth. Therefore, trauma control has always been the need to face the alveolar surgery, scholars have made a lot of efforts and attempts. At present, domestic oral and maxillofacial surgery has paid considerable attention to this, successive research results have been reported, has been involved in the alveolar surgery, especially the complex obstruction surgery trauma control aspects. However, it is undeniable that in many teaching books and clinical work, complications caused by improper surgical operation or irrational perioperative treatment are still common, which increase the pain and unnecessary medical expenses for patients and create obstacles to subsequent restoration and reconstruction of dental function and morphology. The reasons for this may lie in the fact that comparative studies of minimally invasive alveolar surgery in multiple modalities are not yet in-depth, the lack of a timeline continuity study, and the absence of an ideal system of quantitative criteria. The extraction of retained teeth is a common clinical practice in alveolar surgery that involves both bone and soft tissue trauma, and the postoperative response is more pronounced. Improper management can negatively affect the patient’s quality of life and cause secondary trauma to the patient. Maxillofacial surgeons must pay attention to the control of this type of trauma, reduce adverse reactions and complications, and improve surgical comfort. Maximizing the minimum trauma to obtain the best therapeutic effect, so that the patient’s postoperative quality of life is improved. Alveolar surgical operations based on minimally invasive concepts are one of the effective ways in which they can achieve this. Therefore, although extraction of retained wisdom teeth does not involve later restoration, the typicality and comprehensiveness of its surgical operation make it an ideal subject for research on how to minimize trauma in alveolar surgery by using minimally invasive techniques, and thus one of the most important research problems in the field of oral and maxillofacial surgery at the present time.
