PURPOSE Horizontal atrophy in the posterior mandible presents serious limitations on conventional implant placement. The purpose of this study was to evaluate the use of tilted implants angled in a buccolingual direction for restoring atrophic posterior mandibular sectors. MATERIALS AND METHODS A cohort study was performed of 25 patients who had partial prostheses supported by more than 1 imp...

Background. Screw-retained restorations are favored in some clinical situations such as limited inter-occlusal spaces. This study was designed to compare stresses developed in the peri-implant bone in two different types of screw-retained restorations (segmented vs. non-segmented abutment) using a finite element model. Methods. An implant, 4.1 mm in diameter and 10 mm in length, was placed in t...

This study presents, for the first time, an automatic algorithm for surface rendering of a volume consisting of multi-axial cross sections. In computer graphics, although a medical volume is usually considered to consist of sequential parallel cross sections, multi-axial parallel sections that constitute a multi-axial volume have also been frequently used in recent clinical cases. Herein, a mul...

A meso-scale damage modelling framework for composite laminates is assessed against multi-axial experimental data obtained from specimens subjected to combined tension/compression and shear loading using a modified Arcan fixture (MAF). Two made unidirectional carbon fibre-reinforced epoxy plies of different thickness are considered investigate the ply effect on behaviour open-hole specimens. In...

Presented is a study of the tripping strength of asymmetrical longitudinal plate stiffeners subjected to a combination of axial and lateral loads. The loaded edges were taken to be simply supported. The method of analysis is based on the principle of minimum total potential, and ten displacement functions were used to describe the deformations of the plate and stiffeners. First yielding was use...
