Dental implant surgery is a minimally invasive alveolar surgery, and the surgical principles are as follows: 1. The most important principle to follow is the concept of surgical asepsis, and it is important to try not to contaminate the implant and the implant recipient area during the surgery, and to be as precise and gentle as possible during the implant operation, so that the implant reaches a better bone healing as early as possible, then the early stability is better; 2. Prevent side injuries, such as preventing damage to the neurovascular bundle and preventing penetration of the maxillary sinus. In addition, it is necessary to prevent the lateral perforation of the bone wall; 3. prevent thermal damage, which requires constant cooling during the implantation process to prevent bone burns after the bone has been heated too much; 4. consider the position and direction of the implant placement before the surgery, so that the implant can be evenly stressed and achieve a better restoration effect.
