从本研究和文献中的观察结果可以得出以下结论：下颌骨的宽度受到内力和外力的影响。最大的张开、前伸和咬合力导致下颌骨的弓宽减小。正中关系记录时，下颌骨受到水平后缩力，导致牙弓宽度增加。印模制作过程中下颌弓宽度的变化量可以通过防止任何超过20 mm的过度移动和/或开口来最小化。
The following conclusions can be drawn from this study and observations from the literature: The width of the mandible is influenced by intrinsic and extrinsic forces. Maximal opening, protrusion, and biting forces cause the mandible to decrease in arch width. A horizontal retruding force on the mandible for centric relation records caused an increase in arch width. The amount of mandibular arch width change during impression making can be minimized by preventing any protrusive movement and/or opening beyond 20 mm.
