Summary

Non-grafted sinus floor elevation using space-maintaining mesh reliably promotes new bone formation. Both titanium and bioresorbable meshes are predictable for enhancing implant placement in the posterior maxilla.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Dental Implantology
  • Regenerative Medicine

Background:

  • Maxillary sinus pneumatization frequently impedes dental implant placement in the posterior maxilla.
  • Traditional sinus floor augmentation often involves grafting materials, but non-grafted techniques are emerging.
  • Space-maintaining meshes offer a novel approach to support the elevated sinus membrane without grafts.

Purpose of the Study:

  • To assess the predictability of new bone formation following sinus floor elevation using space-maintaining mesh without grafting material.
  • To compare the outcomes of using bioresorbable versus titanium meshes in non-grafted sinus floor elevation.

Main Methods:

  • Eight patients with bilateral maxillary sinus pneumatization underwent lateral window sinus floor elevation.
  • Elevated sinus membranes were supported using either bioresorbable or titanium meshes.
  • Clinical, radiographic, and histological evaluations, including bone core biopsies, were performed at 6 months post-surgery.

Main Results:

  • All patients experienced uneventful healing with evidence of new bone formation.
  • Both radiographic and histological analyses confirmed successful bone regeneration in both mesh groups.
  • Titanium and bioresorbable meshes demonstrated reliability and predictability as space-maintaining devices.

Conclusions:

  • Non-grafted sinus floor elevation utilizing space-maintaining meshes is a predictable method for achieving new bone formation.
  • Both titanium and bioresorbable meshes serve as effective space-maintaining devices in this procedure.
  • This technique enhances the potential for dental implant placement in pneumatized maxillary sinuses.
