Resumen

OBJECTIVES: The purpose of the present study was to evaluate the osseointegration of titanium implants with coin-shaped geometry and different surface roughnesses applying tensile pull out test using sheep as an animal model. MATERIAL AND METHOD: The tensile pull out test was performed with the application of a gradual load perpendicular to the bone-implant interface. The samples surface morphology was characterized by SEM and rugosimetry techniques. Chemical composition of the samples was obtained by EDX analyses. RESULTS: The tensile pull out tests showed that four weeks of healing were insufficient to achieve a satisfactory osseointegration of titanium implants. After eight weeks, the results obtained showed that the ultimate stress mean values of boneimplant interface were influenced by the different surface roughness.
