A Comparison between Xenogenic Deproteinized Bone Substitute Pyrost® and Autologous Bone Graft in the Surgical Management of Simple Bone Cysts Clinical and Radiographic Results

Abstract

The basic principle of surgical treatment of simple bone cysts has remained unchanged over the years, with curettage followed by packing of the defect with autogenic bone graft. With the introduction of ceramic biomaterials, an alternative packing material is available, avoiding the complications associated with cancellous bone harvesting or the use of a bioceramic implant. The aim of this study was to compare bony union and recurrence rate after packing of surgically treated simple bone cysts with either Pyrost® or autogenic spongiosa.
