A Combination of Platelet-Rich Fibrin and Collagen Membranes for Sinus Membrane Repair: A Case Report (Repair of Sinus Membrane Perforation).

Maxillary sinus lift surgery is applied to compensate for the reduced vertical height in the posterior maxilla to facilitate placing a dental implant of a suitable length. Pathological conditions may be accidentally discovered, which necessitate careful assessment and management to prevent the infection of the maxillofacial complex and eventually bone grafting and dental implant failure. This case report describes an approach for the management of Schneiderian membrane perforation associated with the removal of an antral pseudocyst for successful dental implant therapy.

Treatment of severe sinus infection after sinus lift procedure: a case report.

Unlabelled: Maxillary sinus floor augmentation may have a variety of postoperative complications including infection, sequestration of bone, and maxillary sinusitis. Complications can also occur due to a preexisting sinus condition called ostium stenosis. This case report presents a complication after sinus lift and grafting procedure due to an unrecognized ostium stenosis.

Synthesis and characterization of nanocrystalline calcium sulfate for use in osseous regeneration.

Nanoparticles of calcium sulfate (nCS) have potential advantages as a ceramic matrix, scaffold and/or vehicle for delivering growth factors for osseous regeneration in a variety of clinical situations. The objectives of this study were to synthesize and characterize nanoparticles of hemihydrate calcium sulfate (nCS) and to develop a nCS-based system for bone regeneration. A cryo-vacuum method was used to process dihydrate CS into dihydrate nCS, which was then subjected to oven drying to produce hemihydrate.
