Why it matters for dental
Periodontally compromised molars treated with xenograft plus 10% collagen showed significantly better ridge preservation than xenograft alone, giving general dentists and periodontists a practical material choice to reduce future implant or prosthetic complications.
Key points
- Randomized clinical trial published in Journal of Prosthetic Dentistry (available online 6 October 2026) compared xenograft with and without 10% collagen in extraction sockets of periodontally compromised molars.
- Primary outcome focused on ridge dimensional changes; the 10% collagen addition yielded statistically superior preservation of alveolar height and width.
- Study population limited to molars with pre-existing periodontal bone loss, directly relevant to implant planning in compromised sites.
- Trial conducted by Tao Xu et al.; findings provide level-1 evidence clinicians can cite when selecting grafting materials for molar sites destined for future prosthetics.
