Features of the chosen implant system for a study may also influence the outcome of the treatment: The degree of the manufacturer’s tolerances of implants with a conical implant-abutment connection heightens the risk of a mispositioning of the abutment, which cannot be corrected by repeated torqueing. Platform switching (PS) implants tend to have a protective effect on hard implant tissue outcomes, while implants with sandblasted, acid-etched surfaces allow for a shortened unloaded healing period [19,20,21,22,23].

This observational study was designed to document the clinical outcome of newly marketed dental implants and the supra-construction in the daily practice. As a primary objective implants survival rates over 5-year post-loading for single or multiple tooth replacement in the maxilla or the mandible were evaluated. Furthermore, these data were compared to the results of already published clinical studies and retrospective analyses. Secondary objectives included the evaluation of patients’ satisfaction with the restorations, changes of bone level over time, and the peri-implant soft tissue parameters such as plaque index (PI) and sulcus bleeding index (SBI).
