目的 介绍一种将临床实际病例与虚拟仿真牙体预备训练相结合用于口腔修复学临床实习的教学方法,衔接临床前实验室教学与临床实习,提升实习医师牙体预备的技能和质量,并作为临床操作前牙体预备和准入控制的重要环节.方法 采集临床上需行前牙冠修复患者的修复前数字化口扫印模,经数字化美学设计后导入虚拟仿真系统.带教老师指导实习医师行术前牙体预备训练,并参考口腔执业医师实践技能考试评分标准进行评估.术者牙体预备技能和质量满足临床操作要求后,复诊时为患者进行牙体预备并完成诊疗全过程.结果 在基于临床病例的虚拟仿真牙体预备训练后,实习医师的牙体预备精确度更高,耗时更短,患者满意度更高.结论 基于临床病例的虚拟仿真牙体预备训练能使实习医师的牙体预备水平得到有效的提升.
Objective To introduce a pedagogy that combines clinical cases and virtual simulation tooth preparation training in the clinical practice of prosthodontics.It can connect pre-clinical laboratory teaching and clinical practice,and also serve as an important part of the quality and admission control of tooth preparation before clinical practice.Methods Pre-treatment digital impressions were performed for patients who needed an anterior crown restoration.After digital aesthetic design,they were imported into the virtual simu-lation system.Interns finished the tooth preparation training under the guidance of the teacher,and the results were evaluated according to the standard of the Examination of National Clinical Physician Qualification.Only after the interns'tooth preparation skills and quality had met the clinical operation requirements,they returned to the actual clinical cases to prepare teeth for patients to complete the whole process of treatment.Results The training of clinical cases combined with virtual simulation tooth preparation can effectively improve the level of tooth preparation with higher accuracy,efficiency and patient satisfaction.Conclusion The case-based virtual simulation training of tooth preparation significantly improves the tooth preparation skills of interns.
