Synchrotron Analysis of Damaged Extraction Sockets Augmented Using a Synthetic Bone Block: A Pilot Study.

Area of Science:

• Dental implantology
• Bone regeneration
• Oral surgery

Background:

• Alveolar ridge preservation is crucial for successful dental implant placement.
• Damaged extraction sockets present challenges for conventional augmentation techniques.

Purpose of the Study:

• To evaluate the dimensional stability and bone quality of alveolar ridges augmented with synthetic bone blocks (SBB) in damaged extraction sockets.

Main Methods:

• Four participants underwent socket augmentation with SBB and a collagen membrane.
• Intraoral, CBCT scans, and profilometry assessed soft and hard tissue changes at baseline, immediately post-op, and 6 months.
• Synchrotron imaging analyzed bone quality from trephine biopsy samples.

Main Results:

• Minimal soft tissue profile changes were observed throughout the 6-month period.
• Horizontal bone width showed slight reduction (<1 mm) between immediate post-op and 6 months.
• Augmented bone height remained stable, with minimal reduction (-0.21 ± 0.53 mm) over 6 months.
• Synchrotron analysis indicated low to moderate bone quality (16.49% ± 4.91% new bone).

Conclusions:

• Socket augmentation using SBB is a viable technique for regenerating damaged extraction sockets.
• Augmented ridge dimensions were maintained up to 6 months post-procedure.
• Further long-term randomized clinical trials are recommended to validate these findings.
