摘　　要：前牙间隙或缺损是临床修复治疗中的常见问题,针对患牙的不同情况经过数字微笑设计、蜡型等预告技术确认后,常采用贴面、全冠等修复方式来关闭间隙,而传统树脂直接修复技术关闭间隙是目前比较微创的修复方案,但费时费力,外形控制更加依赖经验。运用数字化技术可以更加精确快速地进行美学修复空间的设计、转移,使便捷地关闭前牙间隙及修复缺损成为可能。该技术流程按照实操次序,先后整合了虚拟设计与实体蜡型、实体导板转移设计轮廓形态、就位导板后通过预设通道注射树脂等核心步骤,简化医生的临床操作步骤与时间,与传统手工涂塑技术相比有效地提高了修复效果的可预测性和精确度,降低了技术敏感性,节约椅旁操作时间,为快速关闭前牙间隙及修复缺损提供了新的技术方案。Anterior diastema and tooth defects are common clinical issues in restorative dentistry and are often restored by veneers or crowns based on the results of digital smile design and wax-up. Traditional direct resin restoration for closing a diastema is relatively minimally invasive but is time consuming and laborious, and shape control depends on experience. Digital technology can be used to design and transfer the shape of aesthetic restoration more accurately and quickly;thus, it could close anterior diastema and restore defects easily. According to the workflow, this technical process integrates virtual design and practical wax-up, transfers the designed restoration shape by templates, and injects through the preset channel after the template is in place. This clinical technique simplifies the clinical operation and saves clinical time, which can effectively improve the predictability and accuracy of the restoration and reduce technical sensitivity. This digital workflow provides a new technology for closing diastema quickly and effectively.
