Trial Outcomes & Findings for Multicenter Study Comparing OsseoSpeed TX With OsseoSpeed EV. (NCT NCT01528215)

NCT ID: NCT01528215

Last Updated: 2020-04-22

Results Overview

Marginal bone level will be 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 1 year follow-up visit compared to values obtained at delivery of permanent restoration i.e. loading (baseline). Positive value = bone gain, Negative value = bone loss.

PRIMARY outcome

Timeframe: Evaluated at implant loading and at the 1 year follow-up after implant loading.

Population: In the EV group, 55 subjects (73 implants) completed the 1 year follow-up visit. In the TX group, 60 subjects (84 implants) completed the 1 year follow-up visit. Three of the radiographs were not possible to evaluate, giving an overall number of 59 subjects (81 implants) as basis for the analysis of marginal bone level change.

Marginal bone level will be 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 1 year follow-up visit compared to values obtained at delivery of permanent restoration i.e. loading (baseline). Positive value = bone gain, Negative value = bone loss.

SECONDARY outcome

Timeframe: Evaluated from implant loading to the 5 years follow-up after implant loading.

Population: In the EV group, 40 subjects (52 implants) completed the 5-year follow-up visit. In the TX group, 45 subjects (64 implants) completed the 5-year follow-up visit.

Marginal bone level will be 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 5 years follow-up visit compared to values obtained at delivery of permanent restoration i.e. loading (baseline).
