EVALUATION OF IMPLANT SUCCESS AND SOFT TISSUE HEALTH OF IMPLANT SUPPORTED NASAL PROSTHESES

26180

The aim of this study was to evaluate implant success and soft tissue health of implant supported nasal prostheses. Material and Method: Extraoral or dental implants were placed into the defect site. After a 6-month osseointegration period, abutments were connected to the implants. Bar-clips and magnet retained nasal prostheses were fabricated. The patients were recalled for examination at 6-month intervals after the delivery of the prostheses. Kaplan-Meier survival analysis was used to calculate implant success. Soft tissue reactions were assessed according to scores from 0 to 4. Results: 9 male and 5 female patients were evaluated with a mean age of 58.9 (47-72). Totally 42 implants were placed. Retention was obtained using bar-clips system in 8 patients and magnetic system in 6 patients. The mean follow-up time was 22,4 (10-39) months. Kaplan-Meier analysis showed that cumulative success rate was 84.4 % during observation period. Implant success rates were 85 % for magnetic retention and 84 % for bar-clips retention, 91.3 % for dental implants and 77.3 % for extraoral implants, 92.3 % for nonsmokers and 73.7 % for smokers. During observation period, grade 0 soft tissue reaction was observed in 65.5 % of magnetic retention and 42.5 % of bar-clips retention, grade 1 was observed in 24.1 % of magnetic and 30 % of bar-clips retention, grade 2 was observed 6.9 % of magnetic and 15 % of bar-clips retention. Grade 3 was not observed in magnetic retention while observed in 7.5 % of bar-clips retention. Grade 4 was not seen in any patients. Conclusion: In implant retained nasal prosthesis, the use of dental implants is advantageous when adequate bone structure is present in the defect area. The patients smoking habit appears to be a decisive factor in implant success. Less soft tissue reactions were observed in magnetic retention system compared to bar-clips system.
