Clinical and Microbiological Effects of Surgical Access Combined With Systematically Administered Antibiotics in the Treatment of Peri-implantitis: 1-year Randomized Double-blinded Controlled Clinical Trial

University of Guarulhos·interventional·Posted Jul 5, 2022·Updated Jul 18, 2024

In Brief

A clinical study evaluating Open flap debridement, Er: YAG irradiation, and 3 other interventions for Peri-Implantitis. Completed, enrolled 89 participants across 1 site.

Detailed Summary

This randomized clinical trial evaluates the clinical and microbiological (microbial complexes and changes in the diversity of the submucosal biofilm) effects of MTZ+AMX as adjuncts to anti-infectious surgical treatment plus Er: YAG in the treatment of peri-implantitis.

Interventions

Open flap debridementprocedure

After local anesthesia (2% lidocaine with1:100,000 epinephrine), intrasulcular incisions will be performed to create a horizontal flap extending beyond the adjacent teeth and/or implants. Buccal and lingual full-thickness flaps will be dissected, and granulation tissue will be removed to expose the implant threads and bone defect. The flap will be repositioned in its original position and stabilized with interrupted sutures, which will be removed after 10 days.

Er: YAG irradiationother

An Er:YAG laser (Lite Touch, Light Instruments, Israel) will be used, with an irradiation energy of 20 mJ, frequency of 20 Hz, output power of 0.4 W, and an energy density of 2.76 J/cm2. An 8 mm long sapphire tip will be used in the respective handpiece and not in contact with the titanium surface, with concomitant water spray irrigation, under air 6 and water spray 6, the irradiation angle will be 90 degrees, at a focal distance of 2 mm, with spot size diameter of 1.3 mm

Metronidazoledrug

Metronidazole 400 mg thrice a day for 14 days in the active phase of the periodontal treatment (beginning after open flap debridement).

Amoxicillindrug

Amoxicillin 500 mg thrice a day for 14 days in the active phase of the periodontal treatment (beginning after open flap debridement).

Placebosdrug

Amoxicillin and metronidazole placebos thrice a day for 14 days in the healing phase (beginning after open flap debridement).
