Abstract:
Objective:To explore a type of teaching teeth that can highly simulate natural teeth, and to investigate its application in the practice teaching of crown preparations.Methods:A total of 44 senior students majoring in stomatology Fourth Military Medical University were selected, and each student received the training of crown preparations using interpenetrating polymer network (IPN) enamel-like teaching teeth, extracted natural teeth, and traditional composite resin teeth. Operation assessment was performed, and the operation time of each crown preparation was recorded. According to the requirements for crown preparations, scores were determined from the five aspects of axial converging, space for repair, line angle, shoulder quality, and posture, with 10 points for each aspect and 50 points in total, and the total score was calculated. A questionnaire survey on IPN enamel-like teeth was performed for each student after assessment, and SPSS 23.0 was used to perform the least significant difference t-test and the Tambane's T2 test. Results:There was no significant difference in total assessment score between the IPN enamel-like teeth group and the natural teeth group (37.15±1.17 vs. 37.20±1.20, P>0.05), and both groups had a significantly higher total score than the resin teeth group (31.53±1.41) ( P<0.05). The IPN enamel-like teeth group and the natural teeth group had significantly higher scores than the traditional composite resin teeth group in terms of axial converging, space for repair, and shoulder quality ( P<0.05). The questionnaire survey of the students showed a relatively high score of 3.7-4.9 for each item. Conclusion:Compared with traditional composite resin teeth, IPN enamel-like teeth can more comprehensively and effectively simulate the operation and experience of natural teeth for crown preparations and thus have potential advantages in the practice teaching of crown preparations.
