Expert systems are being utilised increasingly in medical fields for the purposes of assisting diagnosis and treatment planning. A case-based system is a particular type of expert system that uses a store of previously treated cases to provide the knowledge for solving new problems. The aim of this study was to investigate the application of this methodology in the field of orthodontic diagnosis and treatment planning. Using a limited group of features, a case-base of 300 cases was entered into a case-based expert system shell. A test set of 30 consecutive cases was then used to test the diagnostic capacity of the system. The computer-generated treatment plan matched the actual treatment plan in 24 of the 30 cases. The system was also tested for its capacity to handle unusual cases. The system has useful potential.
专家系统在医学领域正越来越多地被用于辅助诊断和治疗规划。基于案例的系统是一种特殊类型的专家系统，它利用先前处理过的案例库来提供解决新问题的知识。本研究的目的是调查这种方法在正畸诊断和治疗规划领域的应用。使用一组有限的特征，将300个病例的案例库输入到一个基于案例的专家系统外壳中。然后使用一组连续的30个病例作为测试集来测试该系统的诊断能力。在这30个病例中，计算机生成的治疗计划与实际治疗计划在24个病例中相匹配。该系统还针对其处理异常病例的能力进行了测试。该系统具有实用潜力。
