Abstract

Different surgical techniques have been developed to reconstruct the posterior maxilla without bone graft. A barrier membrane usually placed internal to the sinus, without stabilizer or bone window, pushed inside the sinus cavity as the ''roof'' of the sinus cavity to preserve the space and help bone regeneration has been used with success. In the present technical report, the heterologous cortical lamina is used for the mechanical support of sinus membranes. The membrane is placed through two lines of 2-3 mm, mesial and distal, created at the top of the antrostomy. The half heterologous membrane is positioned on these lines and pushed to the nose wall of the sinus, and the other half is folded to cover the window. In this way the bone lamina is stable. Cone Beam Computed Tomography was used to evaluate the efficacy of bone lamina to preserve the space in sinus lifting which contributes positively to wound healing and is effective in bone formation without biomaterials.
