Study Arms (2)

Control

PLACEBO COMPARATOR

Open flap debridement + Er: YAG irradiation alone + systemic placebo of metronidazole and amoxicillin thrice a day (TID) for 14 days

Procedure: Open flap debridementOther: Er: YAG irradiationDrug: Placebos

Test

EXPERIMENTAL

Open flap debridement + Er: YAG irradiation alone + systemic metronidazole (400mg) and amoxicillin (500mg) thrice a day (TID) for 14 days

Procedure: Open flap debridementOther: Er: YAG irradiationDrug: MetronidazoleDrug: Amoxicillin

Interventions

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.

Also known as: OFD
ControlTest

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

ControlTest

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

Also known as: MTZ
Test

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

Also known as: AMX
Test

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

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • years of age;
  • in general good health,
  • at least one dental implant in function for at least one year with untreated peri-implantitis defined as: presence of bleeding and/or suppuration on gentle probing, probing depths (PD) ≥ 6mm, and bone levels ≥3mm apical of the most coronal portion of the intraosseous part of the implant.

You may not qualify if:

  • subjects with ≥6 sites with PD ≥5mm;
  • individuals that received periodontal treatment within three months prior to entering the study;
  • inability to perform proper supramucosal and supragingival plaque control (e.g., due to improper restoration design or lack of skills);
  • poorly adapted implant-supported restoration;
  • diabetes;
  • pregnancy;
  • nursing;
  • history of allergies to metronidazole and/or amoxicillin, or any other ingredient of oral care products;
  • alcohol or drug abuse;
  • any systemic diseases that could affect post-operative healing or that required antibiotic premedication for routine dental therapy;
  • long-term use of mouthrinses;
  • anti-inflammatory medications;
  • any other drug that could interfere with the study outcomes within three months prior to entering the study;
  • use of antibiotics within six months prior to entering the study.
