Clinical Trial Summary

Objective: The aim of this prospective observational clinical study is to evaluate the bone level changes in a new implant design, fully tapered and platform switching with the one-time one-abutment protocol after one year of loading. Material and methods: Thirty patients received 1 or 2 implants (6, 8 and 10 mm in length, 3.5, 3.75 or 4.5 mm diameter and bone level design) to replace a single or multiple gap. Radiographic, clinical, esthetic and survival success rate were evaluated after one year of loading. Results: At 12 months post final loading, there were no peri-implant bone loss in any of the cases. Mean marginal crestal bone loss between surgery and crown placement was 0.19 ± 0.17 (p <0.0001). Between surgery and 12 months of follow-up, the mean marginal crestal bone loss was 0.25 ± 0.24 (p <0.0001). There were a SSD between 1 year follow-up and crown placement in PI in the mesial (0.33 ± 0.54 p= 0.003) and distal aspect (0.5 ± 0.73 p= 0.001). The PPD was SSD deeper at 1 year follow-up than at crown placement only in the mesial and distal probing (averaged depth=0.75 and p<0.0005). No statistically significant differences were found for any of the other clinical and est
