Abstract

Implant-bone biomechanics and mechanoadaptation of peri‑implant tissue in space (around and along the length of an implant) and time (3-, 11-, and 24-day following implantation) are important for functional osseointegration of dental implants. Spatiotemporal shifts in biomechanics of implant-bone complex in rat maxillae were correlated with maximum (tensile) and minimum (compressive) principal strain profiles in peri‑implant tissue using a hybrid model; biomechanics paired with digital volume correlation. Spatiotemporal changes in elemental counts and their association with mineral density of the peri‑implant tissue were mapped using electron dispersive X-ray and X-ray fluorescence microprobe techniques. Data provided within are related to biomechanical testing of an implant-bone complex . Data also highlight the power of correlating elemental colocalization with tension and compression regions of the peri‑implant tissues to explain spatiotemporal mechanoadaptation of implant-bone complexes. Further interpretation of data is provided in "Mechanoadaptive Strain and Functional Osseointegration of Dental Implants in Rats [1]."

摘要

种植体-骨生物力学以及种植体周围组织在空间（围绕种植体及沿种植体长度方向）和时间（植入后3天、11天和24天）上的力学适应性，对于牙种植体的功能性骨结合十分重要。利用一种混合模型，将大鼠上颌骨种植体-骨复合体的生物力学时空变化与种植体周围组织中的最大（拉伸）和最小（压缩）主应变分布相关联；生物力学与数字体积相关分析相结合。使用电子色散X射线和X射线荧光微探针技术绘制了种植体周围组织中元素计数的时空变化及其与矿物质密度的关联。本文提供的数据与种植体-骨复合体的生物力学测试有关。数据还突出了将元素共定位与种植体周围组织的拉伸和压缩区域相关联，以解释种植体-骨复合体时空力学适应性的作用。在《大鼠牙种植体的力学适应性应变与功能性骨结合》[1]中提供了对数据的进一步解读。
