PRIMARY outcome

Timeframe: Measured at the 3-year follow-up visit after implant loading.

Population: Intention to treat (ITT), including all participants that received at least one implant, a total of 45 subjects (47 implants). A total of 5 subjects (5 implants) had been lost to follow-up at time of the 3-year follow-up visit, giving an overall number of 40 subjects (42 implants) as basis for the analysis of three year survival rate.

Implant survival rate evaluated clinically and radiographically.

SECONDARY outcome

Timeframe: Measured at the 3-year follow-up visit after implant loading.

Population: 40 subjects (42 implants) completed the 3-year follow-up visit. Analysis of implant stability was performed on the All Patients Treated (APT) population.

Implant stability evaluated clinically/manually (recorded as stable yes/no).

SECONDARY outcome

Timeframe: Measured at the 3-year follow-up visit after implant loading.

Population: 40 subjects (42 implants) completed the 3-year follow-up visit. Protocol deviations were excluded (9 subjects, 10 implants), giving a per-protocol analysis population of 31 subjects (32 implants).

Marginal Bone Level (mm) determined from radiographs and expressed as a difference from a reference point on the implant to the most coronal bone-to-implant contact on the mesial and distal aspect of the implant. Marginal Bone Level expressed in millimeters obtained at the 3-year follow-up visit compared to values obtained at delivery of the temporary restoration i.e. loading (baseline).

SECONDARY outcome

Timeframe: Measured at implant loading and at the 3-year follow-up visit after loading.

Population: 40 subjects (42 implants) completed the 3 years follow-up visit. Protocol deviations were excluded (9 subjects, 10 implants), giving a per-protocol analysis population of 31 subjects (32 implants).

Change in pocket depth expressed in millimeters at time of the 3 years follow-up visit, compared to values obtained at delivery of permanent restoration, i.e. loading (baseline). Negative value = increased pocket depth.
