Minimally Invasive Surgery Combined with Regenerative Biomaterials in Treating Intra-Bony Defects: A Meta-Analysis.

Area of Science:

• Periodontal Surgery
• Regenerative Dentistry
• Evidence-Based Dentistry

Background:

• Minimally invasive surgery (MIS) is increasingly popular in periodontics for treating intra-bony defects.
• The necessity of regenerative biomaterials in conjunction with MIS remains unclear.
• This study evaluates the efficacy of MIS with biomaterials versus MIS alone.

Purpose of the Study:

• To compare clinical outcomes of MIS with biomaterials versus MIS alone in treating periodontal intra-bony defects.
• To determine if biomaterials offer significant advantages when used with MIS.
• To inform treatment decisions based on comparative efficacy and potential cost-effectiveness.

Main Methods:

• A meta-analysis of randomized clinical trials was conducted.
• Searched multiple databases (Cochrane CENTRAL, PubMed, Medline, Embase, etc.) for relevant English publications up to June 2015.
• Key outcomes assessed included probing pocket depth reduction, clinical attachment level gain, gingival margin recession, and radiographic bone fill.

Main Results:

• Four randomized clinical trials met the inclusion criteria.
• No statistically significant differences were observed between the MIS plus biomaterials group and the MIS alone group for clinical attachment level gain (P=0.32) or probing pocket depth reduction (P=0.40).
• Similarly, no significant differences were found in gingival margin recession (P=0.81) or radiographic bone fill (P=0.64).

Conclusions:

• The meta-analysis indicates that MIS with or without biomaterials yields comparable outcomes for periodontal intra-bony defects.
• The findings suggest that cost-benefit analyses are essential when selecting a therapeutic approach.
• Further research into the intrinsic tissue healing capabilities of MIS without biomaterials is warranted to optimize treatment strategies.
