· Female , 52 yo. 患者 女性，52 岁
· She had been wearing a denture for more than ten years, most of remaining teeth were either very loose or badly broken, with exception of one bottom right molar was possible to be kept. 佩戴可摘式假牙十余年，下牙弓所剩牙齿或松动疼痛或破碎， 仅有右下一颗磨牙可以保留。
· After extractions, seven implants were placed. With a computer generated surgical guide, the placed implants were well located and angulated so that C&B type of restorations were easily designed and installed. 所需的牙齿拔除后，应用电脑设计3D打印的种植导板， 将七颗种植体 植入骨内。 由于制导种植技术的精确性， 冠桥类别种植修复体的设计和安装十分容易方便。
