چکیده
This paper aims at evaluating the mechanical performance of endodontically treated teeth. A threedimensional "nite element analysis of teeth is presented. The stress distribution in the teeth restored with a few variants of posts is compared. An improved design of the post is presented. A study on alternative materials for posts has been reported. Conclusions on the ideal shapes and materials of the posts are drawn. 2001 Elsevier Science B.V. All rights reserved.

Effect of Post-Space Preparation on Apical Seal of Endodontically Treated Teeth
ABSTRACT By restoration of pulpally exposed teeth with root canal therapy edentulous areas and neighbouring teeth displacement can be avoided. Prefabricated posts may be used for crown restoration of these teeth. For the preparation of root canal for post placement, Gutta percha should be removed by means of mechanical, thermal and chemical agents. To study the amount of apical leakage in vit...
متن کاملComparison of Root Resorption in Endodontically and Non-Endodontically Treated Teeth in Patients with Fixed Orthodontic Treatment during 2009-2018
Introduction: Apical root Resorption is a common occurrence during fixed orthodontic treatment. This study used panoramic radiographs to compare the rate of root resorption in endodontically-treated and non-endodontically-treated roots. Methods: In this descriptive-analytic study, panoramic radiographs of 20 patients aged 11-18 years with Class I Crowding and Class II Mild Skeletal malocclusio...
متن کاملStress Distribution in Four Restorative Methods in Endodontically Treated Maxillary Premolar: A 3D Finite Element Analysis
Introduction: the Restoration of endodontically treated teeth is critical, and the Awareness of stresses developed by oblique and vertical forces in restorative methods take a great role in treatment plans. Due to the anatomical shape and inherent form of the stress distribution premolars, could be lost by fractures. Some fractures such as vertical fracture which is probable in...
متن کاملLongevity of Amalgam Build-Up Restorations in Endodontically Treated Teeth
Background and Aim: Restoration of endodontically treated teeth is one of the most important and challenging topics in restorative dentistry. Longevity of such restorations is an essential factor in treatment planning. Amalgam build-up is a conservative method for restoration of endodontically treated teeth. Therefore, this study aimed to assess the longevity of this type of restoration in endo...
متن کاملComparing The Rate of External Apical Root Resorption During Orthodontic Treatment in Posterior Permanent Endodontically Treated and Vital Teeth
Background and Aim : One of the concerns about orthodontic treatment is the external apical root resorption(EARR).Therefore, the aim of this study was to compare the rate of EARR in posterior permanent endodontically treated and vital teeth after orthodontic treatment. Materials and methods: This observational and retrospective study was performed on 112 roots in 28 patients in the age range o...
