Trial Outcomes & Findings for Study to Evaluate an Implant With a Sloped Top in Patients With a Sloped Jaw Bone (NCT NCT00807456)

NCT ID: NCT00807456

Last Updated: 2022-11-17

Results Overview

Clinical measurements after implant installation and after 16 weeks to determine bone levels at the buccal and lingual aspects in relation to a fixed landmark on the implant, i.e. the interface between the micro-threaded part and the shoulder at the marginal portion of the implants.The assessments were made using a periodontal probe and distances were measured to the nearest 0.5 mm. Negative value denotes loss of bone.

SECONDARY outcome

Timeframe: 21 weeks, 12 months, 24 months and 36 months post implant placement.

SECONDARY outcome

Timeframe: Baseline and 16 weeks, 21 weeks, 12 months, and 36 months post implant placement

Population: Per-protocol analysis set. All subjects/implants available for each visit are included in below analyses.

MBL alteration assessed by measuring the distance from the implant reference point to the most conical bone-to-implant contact on the mesial and distal side of the implant. The mean of all values for one subject was calculated and used for analysis.
