The strength characteristics of the cement-implant interface were evaluated for smooth-tapered, threaded, and porous-surfaced endodontic implants with the use of different cements. Specifically, tensile and torsional shear strengths were measured for zinc phosphate, polycarboxylate, glass-ionomer, silicophosphate, and AH-26 cements. The results indicated superior shear strength characteristics for threaded endodontic implants on axial loading. However, this strength was diminished when torsional forces were applied. Porous-surfaced endodontic implants showed strong resistance to both axial and torsional loading.
使用不同的粘结剂对光滑锥形、螺纹形和多孔表面的根管内种植体的粘结界面强度特性进行了评估。具体而言，测量了磷酸锌、聚羧酸锌、玻璃离子、硅磷酸和AH - 26粘结剂的拉伸和扭转剪切强度。结果表明，螺纹形根管内种植体在轴向加载时具有优异的剪切强度特性。然而，当施加扭转力时，这种强度会降低。多孔表面的根管内种植体对轴向和扭转加载均表现出很强的抵抗力。
