【摘要】：目的:比较无压力初印模技术与传统初印模技术制取出下颌初模型边缘与内、外斜线的距离及磨牙后垫的形态。方法:20名无牙颌志愿者分别使用无压初印模和传统初印模2种技术为同一志愿者制作2副试验用初模型,分别测量模型内斜线、外斜线到模型边缘的距离及观测磨牙后垫的形态。结果:无压力印模组初模型边缘至内斜线的距离(2.33±0.83)mm比压力组(2.70±0.72)mm明显减小,至外斜线的距离(4.37±0.87)mm比压力组(4.41±0.70)mm也明显减小;其差异具有统计学意义(P=0.000)。无压印模技术制取的初印模磨牙后垫的形变小于传统印模技术。结论:无压初印模制取的初模型边缘伸展更合适,更有利于全口义齿的下一步制作,是值得在临床中推广的技术。
[Abstract]:Objective: To compare the distance between the edge and inside of the initial model of the mandible, the distance of the outer oblique line and the shape of the posterior molar of the mandibular initial model. Methods: 20 non dentomandibular volunteers were used in the same volunteer system as the first model of the same volunteers with the 2 techniques of the unpressed initial impression and the traditional first print die, respectively, to measure the internal deviation of the model. The distance between the line, the outer oblique line and the model edge of the model. Results: the distance between the initial model edge to the inner slope of the non pressure model group (2.33 + 0.83) mm was significantly lower than that of the pressure group (2.70 + 0.72) mm, and the distance to the outer oblique line (4.37 + 0.87) mm was significantly lower than that of the pressure group (4.41 + 0.70) mm, and the difference was statistically significant (P=0.000). The deformation of the rear pad of the first impression molars is less than the traditional impression technology. Conclusion: the initial model edge extension of the unpressed initial model is more suitable and is more beneficial to the next step of the complete denture. It is worth popularizing in the clinic.
