Abdominal Fistula: A Rare Postoperative Complication of Anterior Iliac Crest Graft Harvest in Bimaxillary Reconstruction.

Autogenous bone grafts are considered the gold standard for reconstructing maxillofacial bony defects due to their osteogenic, osteoconductive, and osteoinductive properties. The anterior and posterior iliac crests are commonly used donor sites, providing sufficient quantities of bone for various clinical settings. However, iliac crest bone harvesting can lead to considerable postoperative complications such as wound infection, hematoma, pain, and gait disturbance.

Evaluation of Mechanical and Elemental Properties of Bioceramic-Coated Orthodontic Brackets and Enamel Surface.

Objective:  The aim is to coat orthodontic brackets with two different bioactive materials and to compare the mechanical and morphological properties of coated brackets and tooth surfaces.

Materials And Methods:  A total of 120 stainless steel brackets were divided equally into three groups, that is, the uncoated brackets and nanohydroxyapatite (nHA)-coated, and nanobioactive glass (nBG)-coated brackets using a spin coater machine. The brackets were bonded on the enamel surface and underwent remineralization/demineralization cycles for days 1, 7, 14, and 30.
