Metronidazole as an Adjunct of Non- Surgical Treatment of Peri-implantitis

Summary

The use of systemic antibiotics as and adjunct to non-surgical peri-implant therapy may be an improvement in comparison to these therapies alone. The primary objective is the evaluation of significant changes in probing pocket depth between non-surgical with or without antibiotics. This is a controlled-placebo clinical trial design. Patients with osseointegrated oral implants will be selected and recruited from a university clinic. Oral hygiene instruction and non-surgical debridement at implants will be provided with ultrasonic devices and immediately after, patients will be prescribed: Group Control: A placebo with the same characteristics as the antibiotic Group Test: Systemic antibiotics (Metronidazole 250mg, 2 capsules three times a day, for 7 days Three and six months after non-surgical treatment, clinical parameters will be registered and radiographs compared using reproducible landmarks. Any adverse event will be also recorded.
