Long-term dental implant success and survival - A clinical study after an observation period up to 6 years

摘要

The aim of the present work was to evaluate the long-term results of dental implants and the risk factors associated with implant survival and success rates. 108 patients were examined and the control consisted of medical history taking, clinical and radiographic examinations. The survival rate of dental implants was 96.0% and the success rate was 94.3%. Mucositis was found to be related to patients' age and the number of implant units placed. Peri-implantitis was often found in patients showing low standards of oral hygiene as well as in those who were not coming on regular dental visits. Mucositis was in every 5 th implant site and was mostly seen in patients with prosthetic constructions consisting of 3 or more units as well as in older patients. Oral hygiene and dental control visits are important to maintain good oral health.
