Construction of Individualized Finishing Arch Wire Using the Occlusogram
Get PDFapplication/pdfThe purpose of this study was to test the premise that by tracing occlusograms at the pretreatment stage, one can construct a precise finishing arch wire. The sample consisted of 22 male and 20 female dental students with skeletal Class I and near-normal occlusion. Occlusograms were taken for all plaster dental casts with 0.018 x 0.025 slot edgewise pre-an-gulated and pre-torqued brackets attached to all teeth. Futhermore, our method was applied clinically and an illustrative case is presented. Three different arches (A-arch; a smooth line drawn through the contact points of anterior and posterior teeth, B-arch; constructed by drawing a smooth curve through the cusp tips and incisive edges and C-arch; represented the 0.016 nitinol arch wire) showed a close fit as determined by the fourth degree polynomial equation, with r＾2 of 0.99.journal articl
Immunohistochemistry of BMP-Induced Heterotopic Osteogenesis
Get PDFapplication/pdfPreviously, our research group reported that the third ossification mode, "transchondroid bone formation", was chiefly di splayed in the BMP-induced heterotopic bone formation model 1-3). In this present paper, I describe the following: the histopathological and immunohistochemical features of BMP-induced heterotopic osteogenesis model in mice in the early phase of osteogenesis; and the localization of typical
matrix proteins of cartilage and bone - type I and type II collagen, osteocalcin, and osteopontin- especially in the "chondroid bone matrix". Furthermore, I describe the expression of TGF-β peptide and its mRNA.journal articl
