Regenerative Surgical Treatment of Peri-implantitis Using Nanobone With or

Status Completed

Clinical Trial Summary

The aim of this study was to evaluate the effect of using a synthetic bone substitute with or without simvastatin on regenerative surgical treatment of bone defects associated with peri-implantitis in a 6- months randomized controlled clinical trial.

A total of 30 patients diagnosed with peri-implantitis were randomly assigned to one of two surgical treatment groups (group I: synthetic bone substitute (NanoBone), group II: NanoBone with simvastatin). Clinical measurements included probing pocket depth (PPD), clinical attachment level (CAL), plaque index (PI), modified sulcus bleeding index (mSBI) and mucosal recession (MR). Radiographic bone fill was evaluated at baseline and after 6- months.

Clinical Trial Description

The study was designed as a prospective single-center, parallel group, 6 month randomized clinical trial evaluating the effect of a bone substitute; NanoBone® (Artoss GmbH, Rostock, Germany) (group 1, control group) compared to the same bone substitute with simvastatin (Corvast 80 mg, Egyphar, Egypt) (group 2, test group) for RST of peri-implantitis. A total of 30 patients suffering from peri-implantitis who needed regenerative treatment of at least one peri-implant bone defect were selected and only one implant per patient (the most severe) was evaluated in the treatment groups. The criteria for diagnosing peri-implantitis is based on the consensus report of the eighth European Workshop on Periodontology [34] ; the presence of a peri-implant marginal bone loss ≥2 mm based on baseline periapical radiographs after delivery of the final restoration and bleeding on probing (BOP) and/or suppuration with or without concomitant deepening of peri-implant pockets.

Clinical and radiographic evaluation were conducted at baseline and 6 months postoperatively. Grouping was done using a random number table generated by a third party. They were numbered according to the order of enrolment and assigned to group I or group II. The grouping results were sealed in an opaque envelope and kept by an independent third party. For each patient, cards opened immediately before the surgical procedures. Treatment assignment in each patient was registered by the clinician who assisted in the operations and kept concealed until the completion of the study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
