Responses of Sinus Membrane and Antral Pseudocyst Following Lateral Window Sinus Augmentation with Bone Grafting: A Retrospective Study.

Purpose: To investigate the influence of lateral window sinus augmentation on sinus physiology, including sinus membrane thickness and the outcome of antral pseudocysts.

Materials And Methods: This retrospective study was performed by reviewing all lateral window sinus augmentation procedures, which were done between the years 2013 and 2015. Each enrolled patient had CBCT images preoperatively (T0), immediately postoperatively (T1), and 6 months postoperatively (T2).

The optimization of sintering treatment on bovine-derived bone grafts for bone regeneration: in vitro and in vivo evaluation.

Modifications of sintering temperature and treatment time of bovine-derived bone grafts affect their physicochemical properties and further influence biological activity. Three different temperature sintered bovine-derived bone grafts: group I (300 °C 3 h), group II (300 °C 3 h plus 530 °C 6 h), and group III (300 °C 3 h plus 1000 °C 2 h) and Bio-Oss® were characterized and then compared in vitro for their effects on bone marrow stromal cells (BMSCs) migration, proliferation, and differentiation as estimated by cell migration assay, Alkaline phosphatase (ALP) activity assay, and Alizarin red staining. Further, the four bone grafts were implanted into the calvarial defects of rabbits to evaluate bone regeneration and graft degradation.
