Socket preservation after tooth extraction with autogenous dentin

Official title: Socket Preservation After Tooth Extraction Using Autogenous Dentin in Comparison With Other Techniques

Run by University of Ostrava · NCT07608289 · Data updated 2026-11-12

This study tests four ways to preserve the tooth socket after extraction to see which best maintains bone size for future implants.

Is this trial a fit for you?

Likely a good fit

Adults 18-70 needing non-molar tooth extraction and seeking standard care, without active periodontitis or conditions that impair healing.

Probably not a fit

Patients with factors that severely impair healing or those unlikely to receive implants may not benefit.

What this trial studies

This prospective randomized trial compares four socket preservation methods after non-molar tooth extraction: spontaneous healing with a stitch, collagen sponge alone, collagen sponge with a tricalcium phosphate graft, and autogenous dentin with collagen sponge. The main outcome is the change in ridge width and height measured by CBCT at baseline and six months, with analyses at multiple depths (1, 3, and 5 mm). Participants are adults aged 18-70 without active periodontitis, undergoing extraction for standard care, and without conditions that could affect healing. Subgroup analyses will explore how soft tissue factors influence outcomes.

Why it matters

Potential benefit: If successful, the best preservation method could help maintain jawbone structure for easier, more reliable future implants.

How similar studies have gone: Previous studies have explored socket preservation methods, with varying results; this trial adds direct comparison including autogenous dentin.
