SECONDARY outcome

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

Population: 39 subjects (65 implants) completed the 3-year follow-up visit. Protocol deviations were excluded, giving a per-protocol analysis population of 34 subjects (60 implants). Three of the radiographs were not possible to evaluate, giving an overall number of 32 subjects (57 implants) as basis for the Marginal Bone Level analysis.

Marginal bone level determined from radiographs and expressed as the distance 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 at the 3 year follow-up visit compared to values obtained at delivery of permanent restoration i.e. loading (baseline).

SECONDARY outcome

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

Population: 39 subjects (65 implants) completed the 3-year follow-up visit. Analysis of implant stability was performed on the all patients treated population.

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

SECONDARY outcome

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

Population: 39 subjects (65 implants) completed the 3-year follow-up visit. Protocol deviations were excluded, giving a per-protocol analysis population of 34 subjects (60 implants) for the PPD analysis.

Condition of the periimplant mucosa by assessment of probing pocket depth (PPD). Change in pocket depth expressed in millimeters at the 3-year follow-up visit, compared to values obtained at delivery of permanent restoration, i.e. loading (baseline). Negative value = increased pocket depth.
