建立了一个放电压缩(EDC)制造窗口,用于生产直径为4 mm,长度为7 mm的商业纯钛牙科种植体,带实心钛帽。对于0.500 g的粉末柱,最佳输入能量在0.58-0.87 kJ g− 1范围内。大于0.58 kJ g− 1的输入能量导致植入物扭矩强度超过30 N-cm(固位螺钉拧紧扭矩),而大于0.72 kJ g− 1的输入能量超过46.7 N-cm扭矩强度(在该水平下,固位螺钉在植入前失效)。在整个EDC过程中,保持帽的内螺纹孔和六角头的完整性。EDC过程没有改变组件的强度和/或微观结构,并且珠帽界面比珠-珠界面更坚固。在上述窗口内生产的EDC种植体具有足够的抗压强度和其他物理性能,以满足钛牙科种植体的要求。
An electro-discharge compaction (EDC) fabrication window was established for producing commercially pure porous titanium dental implants of 4 mm diameter and 7 mm length with a solid titanium cap. The optimum input energy was in the range of 0.58–0.87 kJ g−1for a powder column of 0.500 g. Input energy greater than 0.58 kJ g−1resulted in an implant torque strength exceeding 30 N-cm (the retaining screw tightening torque), while input energy greater than 0.72 kJ g−1exceeded 46.7 N-cm torque strength (at this level the retaining screw failed prior to the implant). The integrity of the internally threaded hole and hexagonal head of the cap were maintained throughout the EDC process. The EDC process did not alter the strength and/or microstructure of the components, and the beadcap interface was stronger than the bead-bead interface. EDC implants produced within the aforementioned window have sufficient compressive strengths and other physical properties to meet the requirement for titanium dental implants.
