摘要

近几十年来,骨重建手术取得了前所未有的发展。然而,大多数骨再生产品缺乏针对特定部位进行形态增量的潜力。因此,本研究旨在评估一种新型 CAD CAM 异体块状骨移植在重建复杂的三维牙槽缺损时的组织学和临床效果。此外,该研究还评估了在这些移植物中植入牙科种植体后长达 5 年的临床效果。结果表明,在最初的 17 个移植块中,有 4 个失败(23.5%)。其余 13 个移植块和另外两个替代移植块完全或部分与受体骨部位结合(79%)。在整合块内植入的 29 个种植体中,在长达 5 年的功能恢复期内未发生任何失败,记录的种植体平均边缘骨量损失为-0.5 毫米。

Clinical and Histological Efficacy of Digitally Designed CAD CAM Allogenic Bone Blocks. A Prospective Cohort.

The growth in bone reconstructive surgery has been unsurpassed in recent decades. However, most bone regenerative products lack any potential for delivering site-specific morphologically driven augmentation. It was therefore the purpose of this study to evaluate the histological and clinical incorporation of a novel CAD CAM allogenic block bone graft for the reconstruction of complex 3- dimensional alveolar defects. In addition the clinical outcome of dental implants subsequently placed and loaded within these grafts was assessed with up to 5 years in function. Results demonstrated that 4 of the initial 17 blocks failed (23.5%). The remaining 13 blocks plus an additional two replacement blocks were fully or partially incorporated within the recipient bone site (79%). Of the 29 implants placed within the integrated blocks, no failures occurred with up to 5 years in function, with a recorded mean marginal bone loss by implant of -0.5mm.
