Minimally invasive implant surgery is completed by cutting the mucosa in the implant area without flipping the mucosal flap and placing the implant only. Thanks to the progress of the times, the new dental CT with low radiation dose allows an accurate preoperative assessment of the jaw bone quality, bone volume, nerves, blood vessels and the position of the maxillary sinus. The implant guide made according to 3D digital technology allows implants to be placed in the pre-designed direction, so that dental implants for patients with insufficient bone volume can also avoid the trauma caused by bone grafting. Minimally invasive implant surgery is less traumatic and less reactive after surgery. The implant procedure can be guaranteed to be painless, with no or mild postoperative swelling, which can greatly reduce patient discomfort and increase the comfort of the entire treatment process. Current studies have shown that the success rate of minimally invasive dental implants is comparable to that of implants performed by conventional methods and can fully meet the requirements of patients. This technology responds to the needs of patients and has become the current international trend in the development of implants. The painless minimally invasive dental implant is known as the third set of human teeth, which can help us repair missing teeth, is strong and durable, beautiful and realistic, and is the best dental restoration method at present, which is also favored by the majority of patients with missing teeth. The hospital uses imported implants, such as ITI from Switzerland, Ankylosis from Germany, Zimmer from the United States and other systems, to ensure that patients can get a good tooth under painless and minimally invasive conditions.
