Study data from Baskent University, Faculty of Dentistry update understanding of osteotomy
2009 AUG 4 - (NewsRx.com) -- A new study, 'Stability of locking and conventional 2.0-mm miniplate/screw systems after sagittal split ramus osteotomy: finite element analysis,' is now available. According to recent research published in the journal Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics, "The aim of this study was to evaluate the mechanical stresses over the bone and hardware after sagittal split ramus osteotomy (SSRO) fixed with standard titanium or locking plate/screws using finite element analysis. A 3-dimensional finite element model of the mandible was created, and SSRO and 5 mm advancement was simulated on a computer model." "The model was fixed with either 2.0-mm titanium conventional miniplate/screw or 2.0-mm titanium locking miniplate/screw system, and oblique 200 N bite force was applied. The values of von Mises stresses in the cortical layer of the distal segment using the locking plate system was higher. However, in the cortical layer of the proximal segment the stresses were higher at conventional plate system. In the spongiosa layers of both segments, stresses were higher with the conventional plate system," wrote Y. Oguz and colleagues, Baskent University, Faculty of Dentistry. The researchers concluded: "The locking miniplate/screw system spreads the load over the plate and screws and diminishes the amount of force transfered to each unit." Oguz and colleagues published their study in Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics (Stability of locking and conventional 2.0-mm miniplate/screw systems after sagittal split ramus osteotomy: finite element analysis. Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics, 2009;108(2):174-7). For additional information, contact Y.
