Prevalence of hereditary antithrombin mutations is higher than estimated in patients with thrombotic events.

Antithrombin is the major inhibitor of blood coagulation, primarily inactivating thrombin and factor Xa. Inherited antithrombin deficiency is associated with an increased risk of thromboembolism. Its prevalence is estimated to be about 0.

Sinus lift augmentation using autogenous bone grafts and platelet-rich plasma: radiographic results.

Objectives: Autologous bone grafting and sinus floor elevation is a widely accepted method for reconstruction of the atrophic maxilla. The aim of this investigation was to examine the influence of platelet-rich plasma (PRP) on bone grafting in sinus floor augmentation.

Study Design: A prospective, controlled, randomized study including 34 patients undergoing sinus augmentation before implant placement was designed.
