Bone Loss, Implant Infection
Conditions
Brief summary
The aim of this study is to evaluate the healing of peri-implat tissue following surgical uncovering with the adjunctive use of Chlorohexidine (CHX) gel.
Detailed description
Patients who received implants in our department, and scheduled for surgical uncovering of the implants will be asked to participate in this clinical trial (40) Patients from Department of periodontology, Rambam Health campus, Haifa in Israel will be recruited to Randomized clinical trial; patients will be divided randomly in to 2 groups: 1. Control: following uncovering of the implant a 4 mm height healing abutment will be screwed to the implant (the standard treatment modality) without using Chlorohexidine gel or any other gel. 2. Test group: following implant exposure this group will receive Chlorohexidine 1% gel (Corsodyl®) the gel will be applied on the abutment as well as on the implant internal hex and then a 4 mm healing abutment will be connected.
Interventions
DRUGCorsodyl
following local anesthesia buccal and lingual flaps will be raised minimally, the cover screw will be removed from the implant. In the test group, Corsodyl gel 1% CLOROHEXIDINE will be applied on the implant and the healing abutment.

Masking description
The study will be single blinded. The examiners of the clinical measurements, ELISA samples and the radiographs will be blinded to the patient's group.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Recession depth | 3 MONTHS | Distance from the healing abutment top to the free gingival margin will be measured by periodontal probe at the mid-buccal aspect of the healing abutment. Recession (Rec) is defined as the difference in millimeters between baseline to to 3 months . |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| PROBING DEPTH | 3 MONTHS | The distance between the free gingival margin to the base of the pocket will be measured by periodontal probe in millimeters. |
| Width of the keratinized mucosa (WKM) | 3 MONTHS | the distance in millimeters between the free gingival margin to the mucogingival line will be measured by periodontal probe . |
