During the recent decade, the advanced medical technology has brought the rapid development in the dentoalveo-lar surgery, and the medical concepts of humanity, painless, minimally invasive, safe and comfortable are gradually accepted by the patients and doctors. Many advanced techniques and equipments have been used in the dentoalveolar surgery. This paper would like to make a review on the clinical application and experience of the advanced medical technologies in the tooth extraction, such as the general anaesthetic technique, the nitrous oxide sedative technique, the computer-controlled local anesthesia delivery devices, the electrocardiogram montior, the location of embedded tooth by cone beam CT and minimally invasive surgical technique. Additionally, in this paper we also described the indication, contraindication, advantages and operating essentials of the orthodontic traction technique, ultrasonic bone surgery (piezosurgery) device and the surgery tech-nology for alveolar bone shape and functional preservation in the extraction of tooth. Finally, we introduced the immediate implantation technique used in the dentoalveolar surgery.
