“…Nevertheless, the clinical performance of these two types of retainers was similar after 3 years of follow-up 24 , with comparable success rates in systematic reviews 4,22 . In addition to selecting the correct retainer, clinical procedures must always be adopted to reduce the stress arising from occlusal loading, such as the correct occlusal adjustment and reduction in cusp height of posterior teeth 25 . Two dimensional analysis by means of the finite element method is the best indicated for extremely thin or extensively thick bodies from the mechanical engineering point of view.…”

Objective Results Under the axial load, a higher concentration of stresses was observed around the cast post (166 MPa). In the oblique load simulation, there was a concentration of stresses on the buccal root wall, internally and externally, in the tooth restored with cast post (222 MPa). In both load directions, the glass fiber post dissipated the stress received with greater uniformity (55 to 111 MPa). ConclusionThese data suggested that from the biomechanical point of view, the use of a glass fiber post and composite resin core could be more advantageous than the cast post technique for a mandibular single-rooted premolar tooth.

The aim of this report is to (i) review the current literature on the status of root filled teeth, (ii) analyse the most important factors in decision-making, (iii) discuss the current restorative concepts, and (iv) classify both the evidence and clinical practice in a way that seeks to be clear, understandable and helpful for clinicians. Restoration of root filled teeth represents a challenge for the clinician and remains a controversial subject. The guidelines describe a new classification that is drawn from evidence presented in the literature and also from clinical expertise-based reviews. It describes five categories of teeth.

“…Liu et al 9 suggested that for teeth with limited coronal dentin at the loading location, as maxillary premolars with large-scale tissue loss it was crucial to lower the oblique forces by reducing the lateral occlusal contact area and by preventing contact on the top of the facial cusp, thus protecting the remaining dentin from fracture.…”

a b s t r a c tThe finite element analysis (FEA) is an upcoming and significant research tool for biomechanical analyses in biological research. It is an ultimate method for modeling complex structures and analyzing their mechanical properties. In Implantology, FEA has been used to study the stress patterns in various implant components and also in the peri-implant bone. It is also useful for studying the biomechanical properties of implants as well as IntroductionThe finite element analysis (FEA) is an upcoming and significant research tool for biomechanical analyses in biological research. It is an ultimate method for modeling complex structures and analyzing their mechanical properties. FEA has now become widely accepted as a non-invasive and excellent tool for studying the biomechanics and the influence of mechanical forces on the biological systems. It enables the visualization of superimposed structures, and the stipulation of the material properties of anatomic craniofacial structures. 1 It also allows to establish the location, magnitude, and direction of an applied force, as it may also assign stress points that can be theoretically measured. 2 Further, as it does not affect the physical properties of the analyzed materials it is easily repeatable. 2,3The finite element method (FEM) is basically a numerical method of analyzing stresses and deformations in the structures of any given geometry. The structure is discretized into the so called 'finite elements' connected through nodes. The type, arrangement and total number of elements impact the accuracy of the results. 4 The steps followed are generally constructing a finite element model, followed by specifying appropriate material properties, loading and boundary conditions so that the desired settings can be accurately simulated. Various engineering software packages are available to model and simulate the structure of interest may be implants or jawbone. Previously, when FEA was used in dentistry, various simplified assumptions were made regarding modeling geometry, load, boundaries and material properties.5 Such assumptions inevitably affected the analytical results. In the human body, there are individual variations with respect to E-mail address: shilpa.knp@gmail.com.Available online at www.sciencedirect.com ScienceDirect journal homepage: www.e lsevier.com/locate/jobcr j o u r n a l o f o r a l b i o l o g y a n d c r a n i o f a c i a l r e s e a r c h 4 ( 2 0 1 4 ) 2 0 0 e2 0 3http://dx
