Influence of Radius of Curvature at Gingival Embrasure in Connector Area on Stress Distribution of Three-Unit Posterior Full-Contour Monolithic Zirconia Fixed Partial Denture on Various Amounts of Load Application: A Finite Element Study.

Objectives: To test the hypothesis that radius of curvature at gingival embrasure in connector area significantly affects the fracture resistance of full-contour monolithic zirconia three-unit posterior Fixed partial denture (FPD) on various amounts of load application.

Materials And Methods: In this study, two types of three-dimensional finite element models of a three-unit posterior full-contour monolithic zirconia FPD with two gingival embrasure radii (r I, 0.45 mm and r II, 0.

A Prospective Comparison of Computed Tomography and Magnetic Resonance Imaging as a Diagnostic tool for Maxillofacial Space Infections.

Aims And Objectives: The aim of this work was to assess the advantages and disadvantages of magnetic resonance imaging (MRI) versus computed tomography (CT) in the initial evaluation of maxillofacial space infections by comparing various parameters of the imaging studies and comparing them on a three-point scale.

Materials And Methods: We prospectively evaluated 15 patients with head and neck space infections. All patients underwent CT and MRI using similar slice thickness.
