Finite Element Analysis of Mandibular Anterior Teeth with Healthy, but Reduced Periodontium

Finite element analysis of devitalized teeth

Elimination of a large part of dental tissues during root canal treatment affects the mechanical behavior of devitalized teeth. The present study addresses how much dentin removal affects changes in mechanical behaviors of the intact tooth and tooth with root canal treatment. In order to estimate the tooth weakening, we performed aн experimental assessment of critical force and numerical Finite...

Chewing stress developed in upper anterior teeth with root end resection. a finite element analysis study.

AIM Because pulpless teeth have a higher risk of vertical root fracture, the present study investigated the additional effect of root end resection upon their mechanical resistence. METHODS Finite element analysis (FEA) was used to evaluate the stress and deformations of upper anterior teeth after root end resection while loading them at 100N and 300N. RESULTS Loading teeth with root end re...

Evaluation of root canal anatomy in mandibular anterior Teeth and mandibular and maxillary premolars.

Background: Knowledge about the anatomy of root canals is an important facror in the prognosis of  root canal  therapy .The purpose  of  this  study is to derermine  the root  canal anatomy in  mandibalar anterior  reeth and  premolars by clear and dye peneration method. Materials and methods:In this  study, 350 human mandibular anterior teeth and  mandibular  and  maxillary premolars(from e...

Three-dimensional analysis using finite element method of anterior teeth inclination and center of resistance location.

OBJECTIVE To locate the centre of resistance of consolidated units of four and six anterior teeth during retraction. METHODS Twelve three-dimensional (3D) models were designed in SolidWorks of the anterior segment with four and six teeth and their supporting structure. A proper force system was applied in each model to retract the teeth bodily. The exact location of the centre of resistances ...
