Biomechanical comparison of implant retained fixed partial dentures with fiber reinforced composite versus conventional metal frameworks: a 3D FEA study.
Fiber reinforced composite (FRC) materials have been successfully used in a variety of commercial applications. These materials have also been widely used in dentistry. The use of fiber composite technology in implant prostheses has been previously presented, since they may solve many problems associated with metal alloy frameworks such as corrosion, complexity of fabrication and high cost. The...
متن کاملA comparison of microhardness of indirect composite restorative materials.
The purpose of this study was to compare the microhardness of four indirect composite resins. Forty cylindrical samples were prepared according to the manufacturers recommendations using a Teflon mold. Ten specimens were produced from each tested material, constituting four groups (n=10) as follows: G1 - Artglass; G2 - Sinfony; G3 - Solidex; G4 - Targis. Microhardness was determined by the Vic...
متن کاملFEA in Dentistry: A Useful Tool to Investigate the Biomechanical Behavior of Implant Supported Prosthesis
The use of dental implants is widespread and has been successfully applied to replace missing teeth (Amoroso et al., 2006). Although high success rate has been reported by several clinical studies, early or late dental implants failures are still inevitable. During mastication, overstress around dental implants may cause bone resorption, which leads to infection on the peri-implant region and f...
متن کاملeffect 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 کاملBiomechanical investigation of the supraorbital arch - a transient FEA study on the impact of physical blows
INTRODUCTION As fractures of the supraorbital region are far less common than midfacial or orbital fractures, a study was initiated to investigate whether fist blows could lead to fractures similar to those often seen in the midface. METHODS A detailed skull model and an impactor resembling a fist were created and a fist blow to the supraorbital region was simulated. A transient finite elemen...
