Aim: The aim of this study was to evaluate the stress developed in the bar connecting implants and in the mandible as a result of the elastic deformation of the mandible during mouth opening when using a finite element method (FEM). Materials and methods: A three-dimensional model of an edentulous mandible was generated based on the computer tomography (CT) data of a patient. Two cylindrical im...

In some patients the size and location of the incisive canal may affect treatment planning in the mandible. This case report addresses management of a patient with a large incisive canal, which prevented placement of a dental implant in the intraforaminal area of the mandible. Relevant anatomy is reviewed, treatment considerations are outlined, and potential consequences of inappropriate therap...

introduction: angle and internal position of lateral pterygoid muscle leads to contraction over two half of the mandible in maximum opening and protrusion position so it can affects impression prosthetic procedures. the aim of this study was to evaluate the mandibular flexure in two transverse and antro-posterior dimensions. methods: seventy edentulous patients at mashhad faculty of dentistry a...

There is growing interest, especially for trials in stroke, in combining multiple endpoints in a single clinical evaluation of an experimental treatment. The endpoints might be repeated evaluations of the same characteristic or alternative measures of progress on different scales. Often they will be binary or ordinal, and those are the cases studied here. In this paper we take a direct approach...

The aim of the study was to assess age-related changes in sagittal jaw relationship during pre-pubertal and pubertal development on the basis of angular [ANB, anteroposterior dysplasia indicator (APDI) and A-B plane angle] and linear (Wits, AF-BF, App-Bpp, and App-Pgpp) measurements. Lateral cephalograms of orthodontically untreated subjects were evaluated at 7, 9, 11, 13 and 15 years of age. C...

The shape of the mandible was compared by morphometric methods to ascertain the genetic differences between two substrains of F344 rats, F344/DuCrlCrlj and F344/NSlc. Since these two substrains are clearly different in survival and the incidence of age associated disorders; thus, some genetic differences are suggested to be present between them. Although previous microsatellite analysis did not...

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...

The lingual foramina is a structure located at the side of anterior mandible which houses sublingual artery in turn anastomoses with Inferior alveolar vessels. This that has little information terms anatomy and its variations but it lot significance when comes to any invasive procedure region mandible. With advent Implantology, dentists have be careful while placing implants or proximity forame...

Mandibles and teeth of ungulates have been extensively studied to discern the functional significance of their design. Grazing ungulates have deeper mandibles, longer coronoid processes, flatter incisor arcades, and more hypsodont molars in comparison to browsers. If the functional significance of both mandible and teeth shapes is well-established, it remains uncertain to what extent mandible s...
