An Improved Mechanical Testing Method to Assess Bone-implant Anchorage

Abstract: Recent advances in material science have led to a substantial increase in the topographical complexity of implant surfaces, both on a microand a nano-scale. As such, traditional methods of describing implant surfaces -namely numerical determinants of surface roughness -are inadequate for predicting in vivo performance. Biomechanical testing provides an accurate and comparative platform to analyze the performance of biomaterial surfaces. An improved mechanical testing method to test the anchorage of bone to can… Show more

“…Since BMD is not the only determinant of the bone quality [34], such as bone strength and fragility, although it is measurable value by DXA, the DXA results need to be confirmed by histological observations. It is well-recognized that rat bone is not the easiest model since specimens are small and difficult to align and match precisely for comparison [40].…”

“…A rapidly polymerizing epoxy was needed, to minimize the effects of tissue decomposition (aging) on the mechanical test results. However, when 3 commonly used epoxies were screened, a sharp increase in the temperature of all potting compounds, associated with the exothermic process of rapid polymerization, was observed [28,33]. All compounds produced exothermic temperatures that damaged the mounted tissue ( Fig.…”

“…cubes cut from fresh bone, and tested in shear by gluing the cube surfaces together before applying a shear force [12,17,26]; tensile loading [8,10]; or push-out, which is a commonly used test for adhesive bonding in dental applications [27]. In these studies the mechanical testing regimen did not reflect physiological loading, which is complex and may include bending, compression, shear and torsion [28,29].…”

“…Compared to the smooth-walled osteotomies produced by conventional drills, osteotomies produced by the OsseoShaper are textured (Figure 1). Some investigators speculated that a textured surface represents an optimal site for new bone deposition because it mimics the bone surface left behind after osteoclast-mediated remodeling [49].…”
