Research organization has been set up as proposed in this study and overall framework has been established to achieve the goal of the research. Basic system components in this study are proto-implant system to develop hard-tissue implants, distributed 3D high-level computer-aided design subsystem (3D CAD subsystem), and virtual manufacturing subsystem. These subsystems are highly integrated using ubiquitous network as well as inter/intra-network so that design collaboration environment can be provided to participating researchers. In addition to that, force-feedback interface module is incorporated to the system to improve usability to work on virtual objects.3D CAD subsystem was set up at the University of Tokushima, and collaborative usage of the system has been established using internet connection. Proto-implant subsystem incorporated with desktop milling machine enables us to process some test samples based on the data coming from the 3D CAD subsystem. Moreover, virtual manufacturing subsystem is also based on the data coming from the 3D CAD subsystem. The 3D CAD subsystem not only enables us to design geometrical shape, but also allows us to shape design, function verification, performance evaluation, and other consideration under the virtual environment. Actual manufacturing of implants based on some of those designed data has been carried out using porous ceramic materials to figure out the validity of our manufacturing approach which has been under study. Usability of virtual environment with force-feedback interface has also been studied and some significant results have been obtained.This research also covers the application of our study for supporting technology of dental implant operation as well as hard-tissue implants application, of which results allows us to obtain some significant consideration in terms of actual human welfare.

根据本研究的设想，成立了研究机构，并建立了实现研究目标的总体框架。本研究中的基本系统组件是用于开发硬组织植入物的原型植入系统、分布式3D高级计算机辅助设计子系统（3D CAD子系统）和虚拟制造子系统。这些子系统利用泛在网络以及网络间/网络内高度集成，从而可以为参与的研究人员提供设计协作环境。除此之外，系统中还集成了力反馈接口模块，以提高处理虚拟对象的可用性。德岛大学建立了3D CAD子系统，并通过互联网连接建立了系统的协作使用。原型种植体子系统与台式铣床相结合，使我们能够根据来自 3D CAD 子系统的数据处理一些测试样本。此外，虚拟制造子系统也基于来自3D CAD子系统的数据。 3D CAD子系统不仅使我们能够设计几何形状，还使我们能够在虚拟环境下进行形状设计、功能验证、性能评估等考虑。基于其中一些设计数据的植入物的实际制造是使用多孔陶瓷材料进行的，以弄清楚我们正在研究的制造方法的有效性。还研究了具有力反馈界面的虚拟环境的可用性，并取得了一些有意义的成果。这项研究还涵盖了我们的研究在牙种植手术支持技术以及硬组织种植应用中的应用，其结果允许我们在实际人类福利方面获得一些重要的考虑。
