چکیده
The effect of a restored machined hybrid dental ceramic crown–tooth complex is not well understood. This study was conducted to determine the stress state crown using three-dimensional finite element analysis. Human premolars were prepared receive full coverage crowns and with resin cement. Then, teeth digitized micro-computed tomography scanned an optical intraoral scanner scanner. Three-dimensional digital models generated interactive image processing software for tooth complex. imported into analysis all degrees freedom concentrated on outer surface root To simulate average occlusal load subjected premolar total 300 N applied, 150 at buccal incline palatal cusp, cusp. von Mises stresses calculated under simulated application determined. showed that distribution more in dentine least For cement layer, cusp tip.

Background and Aim: Implant-supported overdentures are a treatment option for edentulous patients. One of the important factors in determining the prognosis of overdenture treatment is to control the distribution of stress in the implant-bone and attachment complex. This study assessed the effect of implant abutment height difference on stress distribution in mandibular overdentures. Materials...

This research pertains to the three-dimensional (3D) finite element analysis (FEA) of the stress intensity factors (SIFs) along the crack front in a spherical pressure vessel coated with functionally graded material (FGM). The vessel is subjected to internal pressure and thermal gradient. The exponential function is adopted for property of FGMs. SIFs are obtained for a wide variety of crack sha...
متن کاملThree-dimensional finite element analysis of the stress distribution pattern in a mandibular first molar tooth restored with five different restorative materials
INTRODUCTION Badly broken or structurally compromised posterior teeth are frequently associated with crown/root fracture. Numerous restorative materials have been used to fabricate indirect full-coverage restorations for such teeth. This study aims to evaluate and compare the effect of restorative materials on the stress distribution pattern in a mandibular first molar tooth, under varying load...
