Humanization: We communicate fully with the patient to understand what the patient wants and where the pain is. We introduce the process of tooth extraction, possible problems during and after the operation, and countermeasures for dealing with them. Post-operative telephone call to understand the patient’s post-operative condition and provide guidance and suggestions on relevant issues. Comfortable: Through communication or necessary auxiliary facilities (such as laughing gas sedation system), try to eliminate the patient’s fear, so that the patient can be completely relaxed mentally and physically and receive treatment and enjoy the service in a very comfortable condition. Painless: Through various anesthesia techniques (such as computer-controlled painless anesthesia techniques), patients can receive treatment without a trace of pain and have their teeth extracted without realizing it. Minimally invasive: Through precise preoperative analysis, a reasonable, effective and convenient surgical plan is formulated, and the affected tooth is extracted with minimal trauma through minimally invasive techniques with the help of minimally invasive instruments, which can reduce patients’ postoperative adverse reactions and fast recovery.
