摘要:

目的 探讨数字化技术在小口畸形牙列缺损修复中的应用。 方法 对1例上牙列缺失下牙列缺损(肯氏Ⅲ类)伴小口畸形的患者应用数字化技术行上颌总义齿修复、下颌可摘局部义齿修复。上牙列缺失采用常规方法制取初印模,制作个别托盘,硅橡胶口内整塑制取上颌终印模。下颌牙弓采用数字化口内扫描获取口内软硬组织数字化印模,通过计算机辅助设计(computer-aid design,CAD)和3D打印技术完成可摘局部义齿金属支架制作。结果 上、下颌义齿固位良好,咬合稳定,患者发音清晰,咀嚼良好,摘戴义齿顺利。1周及1个月后复查,无压痛,患者对咀嚼效率满意,佩戴舒适。结论 口内扫描和3D打印技术成功为小口畸形患者设计和制作例下颌可摘局部义齿,效果满意,为小口畸形患者的牙列缺损治疗提出例一种新的方法和思路。

Abstract:

Objective To explore the application of digital technology in the restoration of partial edentulous patients with microstomia. Methods A patient with microstomia was presented and seeking for the restoration of her full edentulous in the upper jaw and partial edentulous in the lower jaw (Kennedy Ⅲ). A digital intraoral scanning was used to obtain digital impressions of soft and hard tissues in the oral cavity. Computer aided design and 3D printing technology were used to design and fabricate the metal framework. Results The patient had no difficulty to wear or take off the dentures. The maxillary and mandibular dentures showed good retention, stability, mastication function and articulation. There was no tenderness in the one week and one month′s follow-up. And the chewing efficiency was satisfactory. Conclusion This case report successfully designed and fabricated mandibular removable partial dentures for patients with microstomia through intraoral scanning and 3D printing technology. Thus, this work provides a new method and idea for treating partial edentulous dentition with microstomia.

Key words: microstomia, partial edentulous dentition, digital intraoral scanning, CAD/CAM, 3D print, selective laser melting, removable partial denturede
