Brief summary

This is a follow-up study with patients, who participated in the Straumann clinical study CR06/03. The objective is the assessment of long-term data (8 and 10 years after implantation) on the performance of immediate and early (28-34 days post implantation) non-occlusal loaded Straumann Tissue Level Implants with SLActive surface when used to support single crowns or 2-4 unit fixed dental prostheses in the posterior maxilla and mandible. The primary objective is of the study is to analyse the change in crestal bone levels 8 and 10 years post-surgery compared to 6 months, 1 year, 2 years and 3 years post-surgery in the immediate and early loading group.

Detailed description

This is a prospective, post-market, open label, follow-up multicenter study with patients who participated in the Straumann clinical study CR06/03. The total study duration for each patient should be 2 years. In total 2 visits are scheduled in this study. Bone level changes, implant success and survival, performance of the restorative components, and adverse events (AEs) will be assessed. The study device is a CE-marked product and FDA approved. Three centres, one in Portugal and two in Germany, will participate.

Design outcomes

Primary

Measure	Time frame	Description
Crestal bone level change by radiographic assessment	8 and 10 year post-surgery	To evaluate the changes in crestal bone levels (in millimetre) in relation to defined implant reference point and different time points (between baseline at implant insertion and follow-up time points at 8 and 10 years after implant insertion) in the maxilla and mandible of the immediate and early loading groups.

Secondary

Measure	Time frame	Description
Implant survival by clinical and radiographic assessment	8 and 10 year post-surgery	To evaluate the implant survival rate by clinically and radiographically count of implants still in place in the subject's jaw bone at the time of assessment (8 and 10 years post-surgery). The implant survival rates will be compared between the treatment groups (immediate loading and early loading).
Incidence of adverse events and adverse device effects	8 and 10 year post-surgery	Total number of AEs and total number of AEs related to the study treatment (device-related or procedure-related), as well as the total number of subjects affected by at least one adverse event wil be calculated per treatment group.
