Trial Outcomes & Findings for The Efficacy and Safety of Chlorhexidine Gluconate Chip (PerioChip®) in Therapy of Peri-implantitis (NCT NCT02080403)

NCT ID: NCT02080403

Last Updated: 2022-09-13

Results Overview

Pocket depth was measured as the distance from the coronal edge of the gingival margin to the base of the pocket. It was assessed at 4 sites per implant: mesiobuccal, midbuccal, distobuccal, and midlingual. Only one of the 4 sites, usually the deepest, was determine to be target implant.

Treatment
Treatment, 2.5 mg Chlorhexidine Gluconate chip (PerioChip®) inserted every two weeks starting at Baseline for the first 3 months, plus mechanical Subgingival Debridement at Baseline and 3 months. 2.5 mg Chlorhexidine gluconate chip: Subgingival debridement will be carried out for each one of the target implant. Upon completion of the debridement a PerioChip® will be inserted in each one of the target implant.
