fa Evaluation of ultrasound transmission velocity and 3-dimensional radiology in different bone types for dental implantology: a comparative ex vivo study جراحی دهان، فک و صورت Oral and Maxillofacial Surgery پژوهشي Research <p> <strong>Objective</strong></p><p>  To evaluate ultrasound transmission velocity (UTV) for assessment of mechanical bone quality, an ex vivo comparison of different bone types measured with UTV, 2-dimensional (2D) histomorphometry and with 3-dimensional (3D) radiology (cone-beam computerized tomography [CBCT], computerized microtomography [μCT]) was conducted. </p><p> <strong>Study Design</strong></p><p>  Clinical cortical, cancellous, and mixed bone (each n = 6) was measured via UTV (m/s), CBCT (white pixel/black pixel ratio [WP/BP]), μCT (bone volume/total volume [μBV/TV]), and histomorphometry (bone volume/total volume [hBV/TV]). UTV values were correlated with 2D-histomorphometry and 3D-radiologic results. </p><p> <strong>Results</strong></p><p>  For the cortical, cancellous, and mixed bone samples, respectively, UTV values were 1,945.17, 1,266.9,and 1472.2 m/s, WP/BP quotients were 0.96, 0.15, and 0.33, μBV/TV quotients were 0.94, 0.2, and 0.47, and hBV/TV quotients were 0.96, 0.24 and 0.39. Significant correlations between UTV and the other methods were seen (P < .0001). </p><p> <strong>Conclusions</strong> </p><p> Similar to the other methods, UTV is able to discriminate between different bone types ex vivo. </p><hr><p></p><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p><a href="http://www.oooojournal.net/article/S2212-4403(12)00180-0/abstract" target="_blank"><font color="#0000ff"> Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1673&slc_lang=fa&sid=1 Peer W.
