Dental implants are considered to be successful only if they meet the criteria for implant success such as the absence of any clinical mobility in the exercise of function, the absence of peri-implant X-ray transmission zones, and the health of the peri-implant mucosal tissues. The evaluation criteria for the success of dental implants are: 1. The implant does not have any clinical motion when exercising its function. 2. No X-ray transmission zone around the implant. 3, Vertical bone resorption should be less than 0.2mm per year after 1 year of implant restoration. 4. Healthy peri-implant mucosal tissues. 5, Success rate of implant: 85% for maxillary and 90% for mandibular at the end of 5 years, 80% for maxillary and 85% for mandibular at the end of 10 years. 6. There is no continuous and/or irreversible damage, infection, pain, numbness, sensory abnormalities and other symptoms in the mandibular canal, maxillary sinus and nasal floor tissues after implantation.
