Contour Augmentation for Periodontal Defects (CAPD) for Periodontally Compromised Teeth with Horizontal Bone Loss: A...

Area of Science:

• Periodontology
• Dental Implants
• Regenerative Dentistry

Background:

• Periodontally compromised teeth with horizontal bone loss present challenges in achieving optimal aesthetic and functional outcomes.
• Buccal contour augmentation is a potential technique to address these challenges.
• Deproteinized bovine bone mineral (DBBM) is a commonly used grafting material in regenerative dentistry.

Purpose of the Study:

• To assess the effects of buccal contour augmentation using DBBM for periodontally compromised teeth with horizontal bone loss.
• To compare clinical outcomes between open-flap debridement (OFD) with contour augmentation for periodontal defects (CAPD) and OFD alone.

Main Methods:

• A total of 30 subjects were divided into two groups: CAPD (OFD + DBBM) and control (OFD only).
• Clinical parameters including bleeding on probing (BOP), clinical attachment level (CAL), probing depth (PD), gingival recession (GR), keratinized mucosa width (WKM), keratinized mucosa thickness (TKM), and labial cortical plate thickness were measured at baseline and 1 year.
• Pain perception was assessed using visual analog scale (VAS) scores.

Main Results:

• While BOP, CAL, PD, and GR showed no significant differences between groups, CAPD significantly increased WKM and TKM.
• Labial cortical plate thickness significantly increased in the CAPD group but decreased in the control group.
• No significant difference in pain perception was observed between the groups.

Conclusions:

• Contour augmentation for periodontal defects (CAPD) using DBBM is effective in improving keratinized mucosa width and thickness for periodontally compromised teeth.
• The technique also shows promise in enhancing labial cortical plate thickness.
• Further long-term studies are warranted to validate the sustained benefits of CAPD in clinical practice.
