Abstract：
The goal of this clinical report was to present an alternative to traditional flat bone reduction guides, using a custom-designed 3-dimensional (3D)-printed guide according to the future gingival margin of the planned dentition. A 61-year-old woman with concerns regarding her smile appearance was presented. The initial examination revealed excessive gingival show accompanied by excessive overjet. The dentition was in a failing situation. The proposed treatment plan, relying on the sufficient amount of bone and keratinized tissue, consisted of recontouring of the alveolar ridge and gingiva and placement of 6 implants and an FP-1 prosthesis after extraction of all remaining maxillary teeth. Digital smile design was completed, and a fully digitally guided surgery was planned. This consisted of using 3 surgical guides, starting with the fixation pin guide, continuing with the scalloped hard- and soft-tissue reduction guide, and finally the implant placement template. Following the surgery, the patient received a temporary restoration, and on the 4-month follow-up, a new polymethyl meta-acrylate temporary prosthesis was delivered. The patient\'s 7-month follow-up is presented in the article. The report of this triple-template guided surgery indicated that digital 3D planning is a considerably predictable tool to properly establish and evaluate future occlusal plane, smile line, and lip support. Scalloped guides seem to be an excellent alternative to conventional bone reduction guides since they require less bone removal and improve patient comfort during surgery.
摘要：
本临床报告的目的是提出一种替代传统的扁平骨减少指南，根据计划牙列的未来牙龈边缘，使用定制设计的3维（3D）打印指南。介绍了一名61岁的妇女，她对自己的微笑外观感到担忧。初步检查显示牙龈过多，并伴有过度喷射。牙列在失败的情况下。提出的治疗方案,依靠足量的骨骼和角化组织，包括在拔除所有剩余的上颌牙齿后，重新塑造牙槽脊和牙龈的轮廓，并放置6个植入物和FP-1假体。数字微笑设计完成，并计划进行完全数字化引导的手术。这包括使用3个手术指南，从固定销导向器开始,继续使用扇形软组织和软组织减少指南，最后是植入物放置模板。手术后,病人接受了临时修复，在4个月的随访中，新的聚间丙烯酸甲酯临时假体被交付.本文介绍了患者的7个月随访情况。这种三模板引导手术的报告表明，数字3D计划是一个相当可预测的工具，可以正确地建立和评估未来的咬合平面，微笑线，和嘴唇支撑。扇形导向器似乎是传统的骨减少导向器的一个很好的替代品，因为它们需要更少的骨去除，并在手术期间提高患者的舒适度。
