Implant success and survival rates in daily dental practice: 5-year results of a non-interventional study using CAMLOG SCREW-LINE implants with or without platform-switching abutments

Abstract

BackgroundThe performance of dental implants in controlled clinical studies is often investigated in homogenous populations. Observational studies are necessary to evaluate the outcome of implant restorations placed in real-life situations, according to standard practice, and to assess the needs of the patients. The aim of this non-interventional study was to reveal the survival, success, and general performance of CAMLOG SCREW-LINE implants and their restorations in daily dental practice.MethodsSeventeen private practices across five countries participated in this prospective multicenter study. Patients received implants in the maxilla and mandible which were restored either with platform-matching or platform-switching abutments. Patients were followed-up for up to 5 years post-loading. Radiographs and clinical parameters were evaluated and patient satisfaction was evaluated.ResultsFrom a total of 196 patients planned, 185 patients with 271 implants were restored with abutments and fulfilled the follow-up inclusion criteria. Three implant failures were recorded, resulting in a cumulative survival rate of 98.6% after 5 years post-loading. One persistent complication of peri-implantitis occurred. The soft tissue health remained stable, and the papilla height improved after loading. At 5-year follow-up, the mean crestal bone loss was − 0.28 ± 0.60 mm; over 99% of patients reported satisfaction with the restoration as excellent or good.ConclusionsImplants placed and restored with both platform-matching and platform-switching abutments in daily dental private practice achieved excellent clinical outcomes with highly satisfied patients after 5 years of function, confirming the results obtained in well-controlled clinical trials.

Factors Affecting Implant Failure and Marginal Bone Loss of Implants Placed by Post-Graduate Students: A 1-Year Prospective Cohort Study

“…At the one-year follow-up, the survival and success rates were 96.15% and 94.62%, respectively. These data are similar to survival features reported otherwise in the literature [ 20 , 21 , 22 ]. More specifically, they compare well to a one-year study [ 23 ] dealing with 117 C1 implants placed in 60 patients by 7 experienced periodontists; the reported survival and success rates of these active private practice practitioners were 98.3% and 95.4% respectively.…”

A Non-Interventional Study Documenting Use and Success of Tissue Level Implants

“…Cacaci et al [ 31 ], found a survival rate of 98.4% at 36 months. and Beschnidt et al [ 32 ], in 2018, found cumulative survival rates of 100% at 1-year follow-up, 99.6% at 3-year follow-up and 98.6% at 5-year follow-up.…”

Photofunctionalization as a suitable approach to improve the osseointegration of implants in animal models—A systematic review and meta‐analysis

“…Prosthetic dental implant therapy for the replacement of missing teeth is a well-established treatment for the rehabilitation of partially or completely edentulous patients (Beschnidt et al, 2018;Schropp, Wenzel, & Stavropoulos, 2014). Despite the evidence of excellent long-term results, successful osseointegration is still a critical factor for dental implant rehabilitation, mainly in clinically challenging conditions (Benic et al, 2019;Deng et al, 2010;van Steenberghe, Jacobs, Desnyder, Maffei, & Quirynen, 2002).…”
