Alveolar bone remodeling following osseous surgery. A clinical study

Area of Science:

• Periodontology
• Oral Surgery
• Bone Remodeling

Background:

• Advanced periodontitis often necessitates surgical intervention.
• Osseous recontouring is a surgical technique used in periodontics.
• Understanding bone remodeling post-surgery is crucial for treatment outcomes.

Purpose of the Study:

• To monitor alveolar bone crest remodeling after periodontal surgery with osseous recontouring.
• To quantify bone height changes at various sites following the procedure.

Main Methods:

• Longitudinal clinical study involving 17 patients with advanced periodontitis.
• Osseous recontouring performed at 26 surgical sites.
• Bone crest height measurements taken at initial surgery and at 3- and 6-month re-entry evaluations.

Main Results:

• A statistically significant reduction in alveolar bone crest height was observed at 3 and 6 months post-surgery.
• Mean crest height reduction at 3 months: interradicular (0.38 mm), radicular (0.84 mm), furcation (0.79 mm).
• Mean crest height reduction at 6 months: interradicular (0.23 mm), radicular (0.55 mm), furcation (0.88 mm).

Conclusions:

• Crestal resorption is a typical remodeling response following osseous recontouring in periodontal surgery.
• The observed bone loss, while limited, indicates a predictable healing pattern.
• Findings provide insights into the long-term effects of osseous recontouring on alveolar bone height.
