Why it matters for dental

A 5-year RCT comparing block vs particulate DBBM for peri-implant dehiscence defects shows implant survival and defect fill are similar, giving practice owners and surgeons one more evidence-based option when selecting grafting materials without needing to change implant protocols.

Key points

  • Randomized controlled trial (n=38 implants) with 5-year follow-up published in Clinical Oral Implants Research, September 2026.
  • No statistically significant difference in implant survival, marginal bone level, or defect fill between block and particulate DBBM at 60 months.
  • Both groups maintained ≥90 % defect resolution, supporting either material for routine GBR of small-to-moderate dehiscence defects.
  • Results apply to two-stage implant placement with simultaneous GBR; specialists and owners can factor cost, handling time, and supplier availability into material choice.
