This case report presented a fully digital workflow in esthetic dental restoration. A 51-year-old female patient was referred to BDMS Wellness Clinic due to a fracture of the maxillary left central incisor. An immediate dental implant was planned to restore tooth 21 with esthetic crown lengthening of upper front teeth and new zirconia crowns for teeth 11, 12, 13, 21, 22, and 23. Digital impression was made using a digital scanner (PRIMESCAN®, Dentsply Sirona, Bensheim, Germany); surgical guide (Cerec Guide 3, Dentsply Sirona, Bensheim, Germany) was designed by using a designing software (Galileos Software, Dentsply Sirona, Bensheim, Germany) and was milled by using a milling machine (MCXL milling machine, Dentsply Sirona, Bensheim, Germany) to create a precise surgical guide. 3D smile design was done by using the Digital Smile Design (DSD) program, the crown lengthening guide was designed according to DSD designed by using a designing software (Inlab 19 Software, Dentsply Sirona, Bensheim, Germany), and the guide was fabricated by a 3D printer (FormLabs Form 2, Formlab, MA, USA). Provisional crowns (splinted) for teeth 11, 12, 13, 21, 22, and 23 were milled by using polymer (VIPI BLOCK TRILUX®, VIPI Industria, Pirassununga, SP, Brazil) using a milling machine (MCX5, Dentsply Sirona, Bensheim, Germany). The zirconia crowns were designed by using software (Inlab19 Software, Dentsply Sirona, Bensheim, Germany) and milled using the same milling machine. At the implant position, Ti-base is cemented by using an abutment (Multilink Hybrid Abutment, Ivoclar Vivadent, Schaan, Lichtenstein, Germany) with zirconia coping (Cercon base white shade, Dentsply Sirona, Bensheim, Germany) utilized as the abutment. The zirconia crowns (Cercon Xt, Dentsply Sirona, Bensheim, Germany) were sintered and characterized and then cemented. The patient was satisfied with the esthetic outcome of the treatment.
本病例报告展示了美学牙科修复中的全数字化工作流程。一名51岁女性患者因上颌左中切牙折断被转诊至BDMS健康诊所。计划即刻植入牙种植体，对上颌前牙进行美学牙冠延长术，并为11、12、13、21、22和23号牙制作新的氧化锆牙冠。使用数字扫描仪（PRIMESCAN®，德国登士柏西诺德公司，本斯海姆）获取数字印模；使用设计软件（德国登士柏西诺德公司，本斯海姆，伽利略软件）设计手术导板（德国登士柏西诺德公司，本斯海姆，Cerec Guide 3），并使用铣床（德国登士柏西诺德公司，本斯海姆，MCXL铣床）进行铣削，以制作精确的手术导板。通过使用数字微笑设计（DSD）程序进行3D微笑设计，根据DSD使用设计软件（德国登士柏西诺德公司，本斯海姆，Inlab 19软件）设计牙冠延长导板，并由3D打印机（美国马萨诸塞州Formlab公司，FormLabs Form 2）制作该导板。使用聚合物（巴西皮拉松加市VIPI Industria公司，VIPI BLOCK TRILUX®），通过铣床（德国登士柏西诺德公司，本斯海姆，MCX5）为11、12、13、21、22和23号牙制作临时牙冠（夹板式）。使用软件（德国登士柏西诺德公司，本斯海姆，Inlab19软件）设计氧化锆牙冠，并使用同一台铣床进行铣削。在种植体位置，使用基台（列支敦士登公国沙恩市义获嘉伟瓦登特公司，Multilink Hybrid基台）粘结钛基底，使用氧化锆内冠（德国登士柏西诺德公司，本斯海姆，Cercon base白色）作为基台。对氧化锆牙冠（德国登士柏西诺德公司，本斯海姆，Cercon Xt）进行烧结和表征，然后粘结。患者对治疗的美学效果感到满意。
