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

Abstract

Abstract 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.
