Aim: This study aimed at evaluating the influence of cortical layer and surgical techniques on the primary stability of implants in low-density bone.
Materials And Methods: Two solid rigid polyurethane blocks with a density equivalent to 0.32 g/cm simulating cancellous bone were used.
Purpose: To comparatively evaluate the wear resistance of two different implant abutment materials with titanium implants after cyclic loading.
Methodology: Two groups utilizing 20 titanium implants secured in resin blocks, in which 10 titanium implants are connected with titanium abutments (Group I, = 10) and the other 10 titanium implants are connected with Polyether ether Ketone (PEEK) abutments (Group II, = 10). Abutments are cyclically loaded for 550,000 cycles.
Background: Zirconia being a bio-inert material needs to be surface treated to render it more bioactive and enhance its osseointegration potential. However, bioactivity studies focusing on the ability of sandblasting and ultraviolet photofunctionalization (UVP) surface treatments in inducing apatite precipitation using simulated body fluid (SBF) are lacking.
Aim: The aim of the study was to comparatively evaluate the effect of two different surface treatments-sandblasting with 50 µm alumina and UVP with ultraviolet C (UVC) light on the bioactivity of zirconia.
Aim: The aim of this study is to identify and characterize newly formed copolymers by modifying methyl methacrylate (MMA) monomer by substituting cycloaliphatic monomer using Fourier transform infra-red (FTIR) spectroscopy.
Materials And Methods: Heat-cure polymethyl methacrylate (HC-PMMA) experimental specimens were made by dissolving tricyclodecane dimethanol diacrylate (TCDDMDA) at 10% and 20% concentrations in commercially available MMA monomer. Specimens made without TCDDMDA served as the control.
