Comparison of marginal fit between milled and three-dimensional printed polymethylmethacrylate prostheses for single crowns, anterior bridges, and pier abu... The purpose of thisin vitrostudy was to compare the marginal fit of various three-dimensional (3D) printed and milled polymethylmethacrylate (PM...
Analysis of measurements taken in three meridians of a toroidal optical surface can produce a spherocylindrical result without having to locate the principal meridians. This technique is assessed for the anterior corneal surface using keratometry. Good agreement is found with measurements taken in the ...
The utility model relates to a steel plate used for reduction of the fracture, in particular to three-dimensional anatomical acetabulum anterior steel plates suitable for composite acetabular fracture. The steel plate comprises an upper inner alate plate, an upper outer alate plate, a lower alate...
The wear trace was measured in comparison to the non-worn surface (Perthometer SP6; Mahr, D). Relative wear was calculated in relation to a laboratory veneering composite control (Sinfony, 3M Espe, USA). Vickers hardness (Zwick, D; 0.2 kg/60 sec) and the inorganic filler content (TG ...
background. The composite used in the current study (HIPC) has a high percentage of filler along with microceramics in the matrix. Because of the laboratory process, the residual monomer percentage is very low, and the smooth surface shows only minor plaque accumulation and excellent color ...
The porpose of this study was to determine the optimal length of power arms for achieving controlled anterior tooth movement in segmented arch mechanics combined with power arm. A three-dimensional finite element method was applied for the simulation of en masse anterior tooth retraction in segmented...
In simulation, a force of 170 N with 45° oblique to the longitudinal axis of the implant was loaded to the top surface of the abutment. It has been found from the strength and stiffness analysis that the 3i implant system has the lowest maximum von Mises stress, principal stress and ...
(A) intact specimen anterior view, (B) posterior view, (C) section showing cortical and cancellous portions, (D) distal tibia showing fracture fragment with vertical length “L” of 3 cm and percentage of the articular surface (30%). (E–H) representing corresponding 3D models. Full size ...
The strong correlative findings for AS and RVEF are interesting, given that this is a composite vector representing deformation of the endocardial surface (11) and may prove to be an important addition to the echocardiographic assessment of RV systolic function. Cutoff values for impaired RVEF for...
The volumetric change that occurs in the pulp space over time represents a critical measure when it comes to determining the secondary outcomes of regenerative endodontic procedures (REPs). However, to date, only a few studies have investigated the accuracy of the available domain-specialized medical...
