A non-interventional multicenter study to document the implants success and survival rates in daily dental practices of the CONELOG screw-line implant.

OBJECTIVE: This multicenter prospective non-interventional study evaluated the success and survival of the CONELOG implants inserted according to the standard protocol with one- or two-step surgery in daily practice three years after loading. Changes of soft tissue and bone level over time, esthetical outcome, and patient satisfaction were assessed.
MATERIALS AND METHODS: The study included patients in six centers. The implants were used in accordance with standard practice of each particular center, and the use was documented systematically. Failure rate, implant success, bone level changes, different clinical parameters, and patients' satisfaction were assessed.
RESULTS: In total, 130 dental implants were placed in 94 patients (64 female, 30 male). Mean age of patients was 50.4 ± 13.7. At 3-year post-loading, 108 implants in 78 patients were available for evaluation. Success and survival rate were 98.4% after placement and 100% 36 months post-loading. Bone loss from surgery to loading was 0.52 ± 0.55 mm. From loading to 36 months post-loading, the bone level change remained stable. Patient assessments were performed for function, ability to chew, speech, esthetics, and general satisfaction. Patients were very satisfied (82.3%) or satisfied (16.1%). None of the patients was dissatisfied.
CONCLUSION: The 3-year results of this non-interventional multicenter study indicate that the CONELOG implants are reliable and effective over the course of the observation while used in standard conditions of daily environment and confirm the results obtained in controlled clinical trials. CLINICAL RELEVANCE: Performance of CONELOG implants under daily routine is similar to controlled clinical trials.
