数字化赝复体在兔腭瘘修复中的应用

文题释义： 腭瘘：又称腭穿孔和腭瘘孔，腭瘘的临床表现为从牙槽突至悬雍垂某一结构区域遗留口鼻腔贯通的组织缺损，为腭裂术后最常见的并发症。 数字化印模技术：是指将光学、电子技术及计算机图像识别和处理技术结合在一起，通过口内光学扫描，将获取的光学信号转换为计算机所能识别的电子信号，将实体物体转换为虚拟数字信息，从而获得三维数字模型。 背景：数字化印模技术在口腔领域应用广泛，与传统印模技术相比，其更加便利化、精准化。 目的：探讨数字化赝复体在兔腭瘘修复中的应用效果。 方法：用手术方法建立兔腭瘘动物模型，术后1个月利用数字化口内扫描系统对10只兔腭瘘动物模型行口内腭瘘缺损区域数字化扫描，通过数字化印模技术，基于数字化设计，制作兔腭瘘医用硅橡胶赝复体，试戴赝复体后，检查其精确性能、固位性能及封闭性能。实验方案经西南医科大学附属口腔医院动物实验伦理委员会批准。 结果与结论：数字化赝复体修复腭瘘后，赝复体的精确性能、固位性能及封闭性能良好。提示通过数字化印模技术，数字化赝复体实现了对兔腭瘘的精确修复，有一定的临床应用价值。 ORCID: 0000-0001-8250-9393(孙黎波) 中国组织工程研究杂志出版内容重点：组织构建；骨细胞；软骨细胞；细胞培养；成纤维细胞；血管内皮细胞；骨质疏松；组织工程

Application of digital prosthesis in the repair of palatal fistula in rabbits

BACKGROUND:Digital impression technology has been widely used in the oral field.Compared with traditional impression technology,it is more convenient and accurate.OBJECTIVE:To explore the application of digital prosthesis for repairing palatal fistula in rabbits.METHODS:The rabbit models of palatal fistula were established by surgery.One month later,10 rabbit models of palatal fistula were scanned by digital intraoral scanning system.The medical silicone rubber prosthesis for palatal fistula was manufactured by digital impression technology and digital design.After wearing the prosthesis,the accuracy,retention and sealing properties of the prosthesis were examined.The study was approved by the Laboratory Animal Ethical Committee of Hospital of Stomatology,Southwest Medical University.RESULTS AND CONCLUSION:After digital prosthesis repaired palatal fistula,the accuracy,retention and sealing properties of the prosthesis were good.To conclude,the digital prosthesis for palatal fistula repair by digital impression technology achieves accurate repair,and has certain clinical values.
