Summary

Maxillary sinus grafting with bone and coralline particles stimulated bone formation. The sinus lining adapted, showing increased goblet cells but remaining healthy, indicating no chronic sinusitis after augmentation.

Area of Science:

  • Oral surgery
  • Regenerative medicine
  • Histology

Background:

  • Maxillary sinus grafting is common for bone regeneration.
  • Previous research focused on bone, not sinus lining morphology.
  • The response of the maxillary sinus mucosa to grafting is not well understood.

Purpose of the Study:

  • To evaluate histologic changes in the maxillary sinus mucosa after augmentation.
  • To assess the impact of different grafting materials on sinus lining morphology.
  • To determine the health and adaptability of the sinus mucosa post-grafting.

Main Methods:

  • Maxillary sinus augmentation performed in goats using autogenous bone with coralline particles or coralline particles alone.
  • Control group without grafting.

  • Histologic examination of sinus mucosa using light and electron microscopy at multiple time points.

    • Main Results:

    • Coralline particles alone resulted in fibrous tissue encapsulation.
    • Autogenous bone addition to coralline particles enhanced bone formation.
    • Sinus mucosa showed epithelial changes, including goblet cell increase, and a lack of glands.

    Conclusions:

    • Maxillary sinus mucosa adapts physiologically after grafting procedures.
    • The sinus lining remains healthy and does not develop chronic sinusitis.
    • Grafting materials influence bone regeneration and mucosal response.
