OBJECTIVES To determine the stiffness, elastic limit, and strength of a selection of endodontic posts recently introduced onto the market. METHODS Endodontic posts of zirconia (Biopost, Cerapost), titanium (PCR), and carbon fiber (Composipost) were cemented in a brass block and loaded at an angle of 45 degrees in an Instron Testing Machine. From the recorded relationship between force and deflection the three mechanical properties were determined (n = 10 in each group). RESULTS The ceramic… CONTINUE READING
