In the prosthetic treatment of cleft lip and palate, there is a risk of material impaction, aspiration, or mis-swallowing due to the complex maxillary morphology and compromised pharyngeal function. Moreover, expertise is required to ensure the prosthesis harmonizes with the patient's facial esthetics. Recent advancements in digital dentistry offer an effective and safer alternative to conventional methods. In this report, we describe a technique for fabricating a removable partial denture using a combination of digital devices, including an intraoral scanner, model scanner, 3D printer, and milling machine. A 59-year-old woman with a history of left-maxillary cleft lip and palate was treated with a digitally designed and fabricated prosthesis. The technique incorporated novel steps such as a digital altered cast technique and socket splicing method, allowing for improved functional adaptation and aesthetic integration by referencing 3D facial scans. This digital approach eliminated the need for traditional impression materials, reduced the number of clinical visits and adjustment sessions, and contributed to enhanced patient safety and satisfaction. The aim of this report is to demonstrate the clinical application and advantages of digital technology in the fabrication of a removable prosthesis for a patient with cleft lip and palate.
在唇腭裂的修复治疗中，由于上颌形态复杂且咽功能受损，存在材料嵌塞、误吸或误咽的风险。此外，需要专业知识来确保修复体与患者面部美学相协调。数字牙科的最新进展为传统方法提供了一种有效且更安全的替代方案。在本报告中，我们描述了一种使用包括口内扫描仪、模型扫描仪、3D打印机和铣床在内的数字设备组合制作可摘局部义齿的技术。一名有左上唇腭裂病史的59岁女性接受了数字化设计和制作的修复体治疗。该技术纳入了诸如数字改良模型技术和牙槽窝拼接方法等新步骤，通过参考3D面部扫描实现了更好的功能适配和美学整合。这种数字方法无需使用传统印模材料，减少了临床就诊次数和调整次数，并提高了患者的安全性和满意度。本报告的目的是展示数字技术在为唇腭裂患者制作可摘修复体中的临床应用及优势。
