When it comes to tooth extraction, most people are filled with fear, especially when it comes to removing the blocked and buried wisdom teeth that grow at the very back of the teeth, many people are even more afraid of talking about teeth. The violent knocking, large amount of bone removal, intraoperative pain, prolonged opening of the mouth, and violent pulling of the corners of the mouth all cause great trauma and serious psychological shadow to the patient. Many patients are afraid to step into the hospital even if they know that another tooth needs to be extracted. Tong Dongdong, Department of Oral and Maxillofacial Surgery, Stomatological Hospital of Shandong University With the development of stomatology and the wide application of microdynamic technology. Minimally invasive painless tooth extraction technology came into being. The so-called minimally invasive painless tooth extraction technology is the application of modern minimally invasive tooth extraction concept combined with professional surgical microdynamic technology system and minimally invasive surgical instruments for tooth extraction surgical operation, in the state of the patient’s basic painless state of the division of the tooth, the extraction of the affected tooth. The patient’s pain is minimized. The introduction of minimally invasive surgery has revolutionized the concept of traditional tooth extraction over the decades, ushering in a new era of minimally invasive tooth extraction. Minimally invasive tooth extraction, like other minimally invasive surgeries, is characterized by small trauma, short operation time and light postoperative reaction. Minimally invasive tooth extraction adopts specialized pneumatic high-speed head and minimally invasive precision surgical instruments, and through fine surgical operation, the alveolar bone around the affected tooth is not damaged as much as possible, especially not using bone chisel and bone hammer, which completely avoids complications such as bone fracture, damage to neighboring teeth and dizziness that may be caused by previous violent hammering. At the same time, due to the use of a new method of tooth extraction, greatly improve the efficiency and shorten the extraction surgery time, the vast majority of the author’s patients in the extraction time control in less than 10-20 minutes. Good intraoperative anesthesia eliminated the pain, and the peripheral tissues and bone tissues were well protected during the operation, and the swelling and pain of the patients were greatly reduced after the operation. The psychological impact of the surgery on the patient is also much less than traditional tooth extraction. Our hospital to carry out minimally invasive painless tooth extraction technology for several years, the author has been in Shanghai Ninth People’s Hospital, Peking University Stomatology Hospital and the Fourth Military Medical University Stomatology Hospital, Oral and Maxillofacial Surgery Department of the exchange of learning. Taking advantage of the shortcomings, promote the improvement of their own extraction technology.
