A 3-D finite element study of the influence of crown-implant ratio on stress distribution
The purpose of this study was to assess the influence of the crown height of external hexagon implants on the displacement and distribution of stress to the implant/bone system, using the three-dimensional finite element ...
Three-dimensional finite element analysis of stress distribution in retention screws of different crown-implant ratios
The retaining screw of the implant-supported dental prosthesis is the weakest point of the crown/implant system. Furthermore, crown height is another important factor that may increase the lever arm. Therefore, the aim of ...
Reliability of Metalloceramic and Zirconia-based Ceramic Crowns
(SAGE PUBLICATIONS INC, 2010)
Despite the increasing utilization of all-ceramic crown systems, their mechanical performance relative to that of metal ceramic restorations (MCR) has yet to be determined. This investigation tested the hypothesis that MCR ...
Influence of the type of dental trauma on the pulp vitality and the time elapsed until treatment: a study in patients aged 0-3 years
(Blackwell Munksgaard, 2004-06-01)
The purpose of the present study was to determine the influence of the type of trauma on the pulp vitality and the time elapsed until seeking dental care in children aged 0-3 years seen at the Baby Clinic of the Aracatuba ...
In Vitro Study of Fracture Load and Fracture Pattern of Ceramic Crowns: A Finite Element and Fractography Analysis
Purpose: This in vitro study investigated the null hypothesis that metal-free crowns induce fracture loads and mechanical behavior similar to metal ceramic systems and to study the fracture pattern of ceramic crowns under ...
Fracture Load And Phase Transformation Of Monolithic Zirconia Crowns Submitted To Different Aging Protocols
(Operative Dentistry INCIndianapolis, 2016)
Restoration of severely decayed primary incisors using indirect composite resin restoration technique
Caries of primary incisors is a common problem in paediatric dentistry in some countries. The restoration of primary incisors which have been severely damaged by early childhood caries or trauma is also a difficult challenge ...
Correlation between margin fit and microleakage in complete crowns cemented with three luting agents
(Faculdade De Odontologia De Bauru - USP, 2008)
Microleakage can be related to margin misfit. Also, traditional microleakage techniques are time-consuming. This study evaluated the existence of correlation between in vitro margin fit and a new microleakage technique for ...
