A mechanical testing machine is essential in the evaluation of biomaterials. Our present Instron TTM Universal Testing Machine was purchased in 1959 and it has been the backbone of our mechanical testing of biomaterials. This model was last produced in 1974 and we have been advised by the Instron Corporation (see Appendix A) that a number of parts are no longer available (e.g. amplidyne, clutch, vacuum tubes, etc.), and repairs may not be possible. State-of-the-art mechanical testers are servohydraulicly driven and have digital output and are computer controlled, plus have biaxial and uniaxial loading. A mechanical tester of this type is essential in evaluating the mechanical properties of composites, substitutes for dentin, maxillofacial materials, ceramics, chewing studies, and strengths of attachment of cements and implants to bone. The ability of such an instrument to test materials under uniaxial and biaxial loading is essential in the future evaluation and development of many and especially implant materials. The Instron we are proposing to purchase will have adequate loading and displacement ranges with computer controlled servohydraulic biaxial loading and special clamping fixtures for brittle materials (ceramics). We also propose purchasing an x-y recorder and an HP 7090A computer to complete the package (note: Instron does not supply these two items).

机械试验机对于评估是必不可少的 生物材料。我们现有的 Instron TTM 万能试验机是 于 1959 年购买，它一直是我们机械测试的支柱 的生物材料。该型号最后生产于 1974 年，我们一直在 根据 Instron 公司的建议（参见附录 A），许多部件 不再可用（例如 amplidyne、离合器、真空管等），以及 维修可能无法进行。最先进的机械测试仪是 伺服液压驱动，具有数字输出，是计算机 受控，并且具有双轴和单轴加载。机械测试仪 这种类型对于评估机械性能至关重要 复合材料、牙本质替代品、颌面材料、陶瓷、 咀嚼研究以及骨水泥和种植体的附着强度 骨。这种仪器在单轴下测试材料的能力 双轴加载对于未来的评估和开发至关重要 许多材料，尤其是植入材料。我们建议的英斯特朗 购买时将有足够的负载和位移范围与计算机 受控伺服液压双轴加载和特殊夹具 脆性材料（陶瓷）。我们还建议购买 x-y 记录仪 和一台 HP 7090A 计算机来完成该套件（注：Instron 不 供应这两项）。
