Survival and success of implants in a private periodontal practice: a 10 year retrospective study

BACKGROUND: To assess long-term results of implants (XiVE/Frialit-2 Synchro) in a private periodontal practice according to survival and success rates (biological and technical complications) and to detect possible influencing factors, retrospectively. METHODS: Implant placement of at least one implant took place 10 years ±6 months before clinical and radiographic re-examination. Incidence of implant loss as main and incidence of mucositis/ peri-implantitis as secondary outcome were detected. Also, patient-related and implant-related influencing factors were determined by regression analyses. RESULTS: 100 patients (59.0% female) with 242 implants were included into analysis. Survival rate was 94.0% (XiVE: 97.7%; Frialit-2-Synchro: 66.7%). Mucositis was found in 77.6% of all patients, moderate/severe peri-implantitis in 16.3%. In logistic regression analyses statistically significant influencing factors for implant loss was implant type (p < 0.001), for mucositis a wider implant diameter (p = 0.0438) and a high modified Plaque Index (p = 0.0253), for peri-implantits number of implants per patient (p = 0.0075) and a wider implant diameter (p = 0.0079). Technical complications were found in 47 implants (19.4%). CONCLUSIONS: XiVE implants showed a high survival rate over a 10-year follow-up, on the other hand Frialit-2 Synchro implants had worse survival rates. Success rates regarding biological complications are in line with other implant systems.
