The present study reports on the results of a follow-up examination of patient material, 5 years after the installation of the fixed supraconstruction. The patient group comprised 11 individuals. Briefly, a split-mouth technique of treatment was used. In the right side of the mandible the traditional 2-step surgical approach for implant installation was used. In the left jaw quadrant a 1-step surgical procedure was used. A clinical and radiographical examination was performed 5 years after the initial connection of the supraconstruction to the implants. At the 5-year follow-up examination all 61 implants examined at the 18-month follow-up were still in service and found to be clinically stable irrespective of the surgical procedure used. Furthermore, the results of the present clinical and radiographical follow-up study demonstrate that the marginal bone level at implants placed anteriorly in the edentulous mandible and supporting fixed supraconstructions is stable between 18 and 60 months irrespective of whether placed according to a 1-step or 2-step surgical procedure.
本研究报告了在安装固定上部结构5年后对患者材料进行随访检查的结果。患者组由11名个体组成。简要地说，采用了分口治疗技术。在下颌骨右侧，采用传统的两步法种植体植入手术方法。在左颌象限采用一步法手术程序。在上部结构与种植体初次连接5年后进行了临床和影像学检查。在5年的随访检查中，18个月随访时检查的所有61颗种植体仍在使用，并且无论采用何种手术程序，均发现其临床稳定。此外，本临床和影像学随访研究的结果表明，在下颌无牙区前部植入并支持固定上部结构的种植体，其边缘骨水平在18至60个月之间是稳定的，无论采用一步法还是两步法手术程序植入。
