中文摘要：

牙齿形态、功能的治疗是口腔治疗的核心内容，因此，牙体形态教学是口腔医学本科教育的重点之一，其授课质量直接影响着口腔医学生临床实践的能力。近年来我们进行牙体形态教学新模式的探索与实践，循序渐进地开展以下3部分内容教学：牙体形态理论授课结合石膏牙雕刻、网络课程自学结合离体牙辨认、牙列及咬合理论授课结合牙列缺损的蜡牙雕刻。实践证明这种递进式教学模式不但加强了学生对牙体形态的理解和记忆，还可不断提高学生的动手能力及信心，为其今后的口腔临床实践操作打下坚实基础。

英文摘要：

Tooth anatomy and function are the central contents for dental therapy, therefore, the teaching of tooth anatomy is one of the key stomatological education for undergraduates, and its quality directly affects the students′clinical skills. We recently tried a new teaching model, the gradually-advanced teaching method, for tooth anatomy. We carried out the following three parts step by step： theoretical teaching of tooth anatomy plus sculpture of plaster tooth model, online courses plus isolated teeth identification, teaching of dentition and occlusion plus sculpture of dent-al wax tooth in defect dentition. We found that, on one hand, this gradually-advanced teaching model strengthened the students＇ understanding and memory of tooth anatomy and function, on the other hand, it consistently improved students ＇ ability and confidence in their future clinical operations and lay a solid foundation for their dental practice.
