PURPOSE: To evaluate the clinical effect of titanium implants with SLA surface preparation for partial prostheses.
METHODS: One hundred and ninety-one implants with SLA surface preparation were implanted in 130 patients with dentition defect who required dental repair at Yantai Stomatologic Hospital Implant Center. Successful rate of the implant, changes of soft and hard tissue around the implants as well as the stability of the superstructure were recorded and evaluated by regular clinical and X-ray examinations. Data analysis was performed using SPSS 17.0 software package.
RESULTS: Twenty four patients with 31 implants were lost to follow up, one implant which loosened 1 week after operation was extracted. Four implants were found with peri-implantitis. The dropout rate, survival rate and successful rate was 18.46%, 99.38% and 96.88%, respectively. No obvious biological complications were observed in 155 successful implants during the observation period. Eight years later, the marginal bone resorption reached to (1.34±0.52) mm. After 8 years, a total of 25 implants had mechanical complications, including superstructure screw mobility, falling off of the crown, porcelain fracture of restorations, implant fracture and the prosthesis success rate was 83.87%.
CONCLUSIONS: SLA surface implant can not only achieve good bone integration, but also long-time maintainanance of the soft tissue around the implant and implant superstructure at a healthy and stable state,the clinical effect is better than other dental implants.
