Assessment of different materials used for fabrication of fixed free fixed dental prostheses: finite element analysis

Abstract Background This research assessed three materials to be used in the fabrication of fixed free fixed dental prosthesis using finite element analysis.Total deformation, Von Mises stress maximum amounts and sites on both the bone, and the fixed dental prosthesis body were compared.Methods 3D finite element model was made for the tested fixed

Time-varying auditory gain control in response to double-pulse stimuli in harbour porpoises is not mediated by a stapedial reflex

Echolocating animals reduce their output level and hearing sensitivity with decreasing echo delays, presumably to stabilize the perceived echo intensity during target approaches.In bats, this variation in hearing sensitivity is formed by a call-induced stapedial Mattress Accessory Package reflex that tapers off over time after the call.Here, we tes

Evaluation of the Chemical Compounds and Antibacterial Properties of the Aerial Parts of Persian Heracleum Persicum Essence

BACKGROUND AND OBJECTIVE: Emergence of resistant microbial strains due to the consumption of chemical preservatives and medications, as well as uncertainty about the consumption of foods containing synthetic preservatives, have resulted in the growing popularity of natural preservatives.This study aimed to identify the chemichal compounds found in
