PURPOSE The purpose of this study was to propose finite element (FE) modeling methods for predicting stress distributions on teeth and mandible under chewing action. MATERIALS AND METHODS For FE model generation, CT images of skull were translated into 3D FE models, and static analysis was performed considering linear material behaviors and nonlinear geometrical effect. To find out proper bou...

This paper presents an automated procedure to generate a three-dimensional finite element model of an individual patient’s mandible with dental implants inserted. The reconstruction of the geometry as well as the modeling of the material properties for the different types of bone in the jaw is based on CT data. For this purpose various methods of image processing, geometric modeling and finite ...

The article presents the current possibilities in field of modeling and manufacturing models anatomical structures, surgical templates, implants terms planning procedures area ​​the mandible. In first stage, 3D reconstruction mandible geometry using 3D-Slicer software was presented. next step process consisted resection templates supplementing loss bone structure last stage additive FDM method ...

PURPOSE Stress distribution and mandible distortion during lateral movements are known to be closely linked to bruxism, dental implant placement, and temporomandibular joint disorder. The present study was performed to determine stress distribution and distortion patterns of the mandible during lateral movements in Class I, II, and III relationships. METHODS Five Korean volunteers (one normal...

INTRODUCTION Simulation and modeling represent promising tools for several application domains from engineering to forensic science and medicine. Advances in 3D imaging technology convey paradigms such as augmented reality (AR) and mixed reality inside promising simulation tools for the training industry. METHODS Motivated by the requirement for superimposing anatomically correct 3D models on...

introduction: excessive temperature rise during drilling of the mandible for dental implant placement might damage adjacent osseous tissues. various factors affect temperature rise, including the geometrical parameters of surgical drills, one of which is the drill bit head angle. the aim of this research was to determine suitable drill bit head angle to induce minimum temperature rise during ma...

BACKGROUND Free fibula osteocutaneous flaps are the primary option for reconstruction after segmental mandibulectomies. This study evaluates the impact of CT-guided preoperative planning on operative outcomes after free fibula mandible reconstruction. METHODS We conducted a retrospective review of all patients undergoing free fibula reconstruction of the mandible from 2002 to 2011. RESULTS ...

OBJECTIVES The present study aimed at performing a histological evaluation of the response of temporal bone tissue to a change of direction of the force vector of the mandible in relation to the base of the skull. MATERIAL AND METHODS Adult rabbits were assigned into four groups with two control and four experimental animals in each group. experimental animals underwent surgery, which resulte...

The mechanical behavior of mammalian mandibles is well-studied, but a comprehensive biomechanical analysis (incorporating detailed muscle architecture, accurate material properties, and three-dimensional mechanical behavior) of an extant archosaur mandible has never been carried out. This makes it unclear how closely models of extant and extinct archosaur mandibles reflect reality and prevents ...
