STUDY DESIGN Axial pullout tests using fresh cadaveric thoracolumbar vertebral bodies. OBJECTIVES To evaluate the effect of a new injectable calcium phosphate cement on the axial pullout strength of both revised and augmented pedicle screws in comparison with polymethyl methacrylate and in terms of injection method. SUMMARY OF BACKGROUND DATA Failure of pedicle screws by loosening and back ...

STATEMENT OF PROBLEM Increasing the thickness of intraoral autopolymerizing hard denture base liners may result in a temperature rise and a burning sensation for patients. PURPOSE The purpose of the study was to determine whether increasing the thickness of hard autopolymerizing reline resin increases the temperature of the basal seat area of a denture during the polymerization process. MAT...

OBJECTIVE The purpose of this study is to compare the biocompatibility and the effect in osteoblasts of polymethyl methacrylate alone, and mixed with hydroxyapatite in different concentrations of 5, 10, 15 and 20%, without exceeding 20%, as it can alter mechanical properties of the composite. MATERIAL AND METHODS Experimental study comparing osteoblast response to Polymethyl methacrylate alon...
