Summary

This study found that the synthetic bone graft Ionogran, with or without guided bone regeneration (GBR), increased alveolar ridge volume in dogs. Histological analysis confirmed Ionogran

Area of Science:

  • Dental implantology
  • Biomaterials science
  • Regenerative medicine

Background:

  • Alveolar ridge augmentation is crucial for dental implant success.
  • Synthetic bone grafts offer an alternative to autografts.
  • Guided bone regeneration (GBR) enhances bone volume.

Purpose of the Study:

  • To evaluate the clinical and histological efficacy of Ionogran, a synthetic bone graft, for alveolar ridge augmentation.
  • To compare Ionogran used alone versus in combination with GBR.

Main Methods:

  • Five beagle dogs underwent premolar extractions.
  • Alveolar ridges were augmented with Ionogran, with or without an expanded polytetrafluoroethylene barrier (GBR).
  • Clinical (volumetric analysis) and histological evaluations were performed at 1 and 3 months post-surgery.

Main Results:

  • Both Ionogran alone and Ionogran with GBR increased alveolar ridge volume.
  • No significant difference in augmentation height was observed between groups.
  • Histology showed Ionogran is biocompatible, with limited bone formation at the graft-bone interface.

Conclusions:

  • Ionogran is a safe and biocompatible synthetic bone graft material for alveolar ridge augmentation.
  • The addition of GBR did not yield significant differences compared to the graft alone in this study.
  • Further research is needed to optimize bone formation with synthetic grafts.
