Experimental fixation of bone cement and composite resins to bone.
1979
The aim of this study was to ascertain whether the use of liquid acrylic resin or NeoCryl XK-53 acrylic emulsion or etching of the bone surface with phosphoric acid or the application of both these methods would improve the bonding of CMW bone cement or Concise and Silar composite resin to bone. The test materials were applied to fresh cortical bovine bone. Their bonding capacity was measured by the Instron Universal Testing Machine. The surfaces of the test materials and the bone surfaces were examined by means of optic microscope or scanning electron microscope. The bonding strength of the bone cement and composite resins as such were found to be of the same magnitude. A three- to five-fold improvement was obtained with liquid acrylic intermediary material. Acid etching impaired the bonding.
