Alveolar Ridge Preservation on Maxillary Molars Using Solvent Dehydrated Bone Allograft and d-PTFE Membrane: A CBCT...

Area of Science:

• Dentistry
• Oral Surgery
• Regenerative Medicine

Background:

• Alveolar bone resorption following tooth extraction can compromise dental implant outcomes.
• Ridge preservation techniques aim to maintain alveolar bone volume and morphology.
• Solvent-dehydrated bone allograft and nonresorbable membranes are utilized in bone regeneration.

Purpose of the Study:

• To evaluate vertical and horizontal alveolar bone resorption after maxillary molar extraction.
• To assess the efficacy of solvent-dehydrated bone allograft (Puros) with a nonresorbable membrane for ridge preservation.
• To analyze bone dimensions and histological outcomes at the time of implant placement.

Main Methods:

• Extraction of eight single maxillary molars.
• Application of solvent-dehydrated bone allograft (Puros) and a nonresorbable membrane for ridge preservation.
• Clinical and radiographic measurements of ridge dimensions at 4 months post-extraction.
• Histologic analysis of bone tissue.

Main Results:

• Mean buccal bone height reduction observed: 1.51 mm (midpoint), 0.88 mm (mesial), and 1.16 mm (distal).
• Implants were placed without additional augmentation; six of eight required internal sinus elevation.
• The technique demonstrated success in preserving alveolar bone dimensions.

Conclusions:

• Solvent-dehydrated bone allograft combined with a nonresorbable membrane is a viable technique for maxillary molar ridge preservation.
• The technique effectively minimizes alveolar bone resorption, facilitating predictable implant placement.
• Further research may explore long-term outcomes and variations in augmentation needs.
