Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 26-45 with completely or partially impacted mandibular third molars in good oral health.
✕Probably not a fit
Patients with systemic health issues, uncontrolled periodontal conditions, or those who smoke heavily may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study evaluates the effectiveness of using a xenograft combined with a barrier membrane to prevent the formation of deep periodontal pockets following the extraction of impacted mandibular third molars. The approach aims to enhance site preservation and promote better periodontal health for adjacent second molars. By utilizing organic bone xenograft material and guided bone regeneration techniques, the study seeks to address complications arising from impacted teeth and improve overall oral health outcomes. Participants will be monitored for changes in periodontal pocket depth over a six-month period post-surgery.
Why it matters
Potential benefit: If successful, this approach could significantly reduce the risk of periodontal disease in patients with impacted third molars.
How similar studies have gone: Previous studies have shown promising results with similar approaches in periodontal therapy, indicating potential for success.
