effect of taper on stress distribution of all ceramic fixed partial dentures: a 3d-fea study
statement of problem: mechanical failure of ceramic materials is controlled by brittle fracture, mostly occurred in tension. in 3-unit all-ceramic fpds the connector area is considered to be at fracture risk because of tensile stress concentrations. purpose: the aim of this fe analysis was to evaluate the effect of taper on stress distribution in all-ceramic fpds. materials and methods: in this...
متن کاملInfluence of stress simulation parameters on the fracture strength of all-ceramic fixed-partial dentures.
OBJECTIVES This in vitro study tested the influence of diverse stress simulation parameters on the fracture strength of all-ceramic three-unit fixed partial dentures (FPDs). METHODS All-ceramic FPDs made of Empress 2 (Ivoclar-Vivadent, FL) were exposed to thermal cycling and mechanical loading (TCML) with varying loading parameters such as chewing force (amount, frequency), thermal loading, l...
متن کاملStress analysis of partial dentures.
Three-dimensional photoelastic stress analysis has been used to examine the stresses on disjunct partial dentures. Three types of denture were studied: tooth-borne, mucosa-borne and toothand mucosa-borne. The method of calculating the stresses is outlined and the significance of the findings is discussed. INTRODUCTION There are several ways of carrying out a stress analysis in connection with p...
متن کاملVertical marginal gap & retention of ceramic full coverage & inlay retained ceramic fixed partial dentures
Objectives: A comparison study between ceramic full coverage FPDs & 3 designs of ceramic inlay retained FPDs regarding vertical marginal gap & retention. Materials & Methods: Twenty samples were constructed and divided into 4 groups according to the type of restorations: full coverage, inlay-shaped (occluso-proximal inlay + proximal box), tub-shaped (occluso-proximal inlay), and proximal box-sh...
متن کاملReverse Engineering and FEM Analysis for Mechanical Strength Evaluation of Complete Dentures: A Case Study
Complete dentures are used in social healthcare of the seniors. These frequently deteriorate, due to the fragility and structural defects of the materials from which are realized, and also due to the accidents produced because of the patients disabilities. The loss of teeth impairs patients’ appearance, mastication ability and speech, thus upsetting the quality of their social and personal life...
