Peri-Implant Reconstruction With Autogenous Bone and Electrolytic Therapy: A Randomized Controlled Clinical Trial

Area of Science:

• Dental Implantology
• Periodontology
• Regenerative Medicine

Background:

• Peri-implantitis, a prevalent complication of dental implants, necessitates effective reconstructive therapies.
• Autogenous bone grafts are a common approach for reconstructing bone defects associated with peri-implantitis.
• Adjunctive therapies, such as electrolytic cleaning (EC), are being explored to enhance treatment outcomes.

Purpose of the Study:

• To assess the efficacy of peri-implant reconstructive therapy using autogenous tuberosity bone grafts.
• To evaluate the added benefit of electrolytic cleaning (EC) as an adjunct to surgical treatment for peri-implantitis.

Main Methods:

• A randomized controlled clinical trial involving 31 patients diagnosed with peri-implantitis.
• Comparison between a control group (mechanical debridement and bone grafting) and a test group (additional EC).
• Assessment of clinical parameters (probing pocket depth, gingival index, bleeding on probing) and radiographic bone fill over 12 months.

Main Results:

• Both groups showed significant improvements in clinical parameters (PPD, GI, BOP) compared to baseline.
• The test group (with EC) exhibited significantly greater radiographic bone defect fill at the mesial site (4.6 mm vs. 2.5 mm).
• No statistically significant differences in clinical outcomes or bone fill at other sites were observed between the groups.

Conclusions:

• Autogenous bone grafting effectively improves clinical and radiographic outcomes in peri-implantitis treatment.
• Electrolytic cleaning (EC) did not provide statistically significant additional clinical benefits in this study.
• Further research, potentially including histological analysis, is needed to fully understand the role of EC in re-osseointegration.
