Abstract

Purpose: This research aimed to develop an innovative method for designing and fabricating nasal prostheses that reduces anaplastologist expertise dependency while maintaining quality and appearance, allowing patients to regain their normal facial appearance.

Methods: The method involved statistical shape modeling using a morphable face model and 3D data acquired through optical scanning or CT. An automated design process generated patient-specific fits and appearances using regular prosthesis materials and 3D printing of molds. Manual input was required for specific case-related details.

Results: The developed method met all predefined requirements, replacing analog impression-making and offering compatibility with various data acquisition methods. Prostheses created through this method exhibited equivalent aesthetics to conventionally fabricated ones while reducing the skill dependency typically associated with prosthetic design and fabrication.

Conclusions: This method provides a promising approach for both temporary and definitive nasal prostheses, with the potential for remote prosthesis fabrication in areas lacking anaplastology care. While new skills are required for data acquisition and algorithm control, these technologies are increasingly accessible. Further clinical studies will help validate its effectiveness, and ongoing technological advancements may lead to even more advanced and skill-independent prosthesis fabrication methods in the future.

计算机辅助设计和制造鼻假体:使用统计形状建模的半自动化算法。
目的:本研究旨在开发一种设计和制造鼻假体的创新方法,在保证质量和外观的同时,减少对整形外科医生专业知识的依赖,使患者能够恢复正常的面部外观:方法:该方法涉及使用可变形面部模型和通过光学扫描或 CT 获取的三维数据进行统计形状建模。自动设计流程使用常规假体材料和三维打印模具,生成针对患者的合身度和外观。与具体病例相关的细节需要手动输入:结果:所开发的方法满足了所有预定要求,取代了模拟印模制作,并与各种数据采集方法兼容。通过这种方法制作的假体与传统制作的假体具有同等的美观度,同时减少了假体设计和制作过程中对技能的依赖:结论:这种方法为临时性和确定性鼻假体的制作提供了一种很有前景的方法,并有可能在缺乏鼻假体护理的地区实现远程假体制作。虽然数据采集和算法控制需要新的技能,但这些技术越来越容易获得。进一步的临床研究将有助于验证其有效性,而技术的不断进步可能会在未来带来更先进的、不依赖技能的假体制作方法。
