This study aims to apply a new expert system to design removable partial denture (RPD) framework. The RPD design is completed in three steps, namely, "selecting missing teeth", "selecting abutment condition", and "selecting personalized clasp". The system can help auxiliary dentists develop personalized treatment plans to reduce their clinical workload. It can also generate a dental preparation guideline for clinical preparation, which can prevent tooth preparation mistakes. By generating the standard electronic drawings of the framework design, the system can reduce the inconvenience caused by manual drawing, thereby facilitating dentist-technician communication and reducing the rate of remade.
运用专家系统辅助口腔可摘局部义齿支架的设计，通过“缺失牙位”、“基牙状况”和“个性部件替换”3个步骤逐次多级地完成可摘局部义齿支架设计，辅助医生快速制定个性化的治疗方案，优化临床路径，减轻临床工作量。通过本系统生成牙体预备方案以指导临床备牙，防止医生在繁忙的椅旁工作中遗漏牙体预备，减少由此带来的义齿返工率。同时本系统可生成规范的支架设计电子图纸，降低手工图纸带来的不便利性，以利医技沟通，减少返工率。.
