Purpose: Among the components of the dental implant, there are various designs and combinations of implant fixtures and abutments. SF implants (Snucone co., Ltd. Korea) are tapered fixtures using a locking tapered abutment. The purpose of this retrospective study was to evaluate cumulative survival rate (CSR) of SF fixture (Snucone co., Ltd. Korea) followed for 9 years.
Materials and Methods: From December 2008 to October 2009, 37 patients with 86 SF implants of Snucone® who had surgery at Chungju Hankook hospital and the follow-up period was nine years. The patients’ gender, age, position of implanted fixtures, diameter and length of implants, bone graft, duration from implantation to secondary operation, the changes of marginal bone around the implant and the survival rate were analyzed.
Results: A total of 37 patients, there were 19 male (51.4%) and 18 female (48.6%). Patient ages ranged from 30s to 70s. Of the 86 implants, 36 (41.9%) were placed in the maxilla and 50 (58.1%) were placed in the mandible. The diameter of the most placed implants was 5.3 mm (34.9%) and the length was 8.0 mm (39.5%). Moreover, 59 (68.6%) implants were implanted with bone graft of the total 86 implants. The average period from implant placement to secondary surgery was 5 months. The survival rate of the implant was 98.8% and the average marginal bone resorption was measured ?0.95±1.84 mm.
Conclusions: Although SF implants of Snucone® show favorable clinical outcomes with high survival rate and lower marginal bone resorption during the 9-year follow-up period as compared to previous reports, cumulative evaluations and researches should be conducted in the future.
