This study evaluated the pretreatment influence of occlusal splints and relines on mandibular movements (MM) and vertical dimension of occlusion (VDO) in longstanding complete denture wearers.
A total of 30 volunteers were randomly assigned to three groups (n = 10): control (C), relining of old denture (RD), and occlusal splints (OS). Individual extent of MM was assessed via intraoral Gothic arch tracings and the VDO using posed frontal images taken at three time points.
The OS group showed statistically significant differences when compared with the other groups (P < .05).
Both MM and VDO were significantly improved by use of occlusal splints pretreatment.
本研究评估了咬合垫和重新衬垫对长期全口义齿佩戴者下颌运动(MM)和正中颌位垂直距离(VDO)的预处理影响。
共 30 名志愿者被随机分为三组(n = 10):对照组(C)、旧义齿重衬(RD)和咬合垫(OS)。通过口腔哥特式弓描记和在三个时间点拍摄的正面定位图像来评估个体 MM 的范围。
与其他两组相比,OS 组的差异具有统计学意义(P <.05)。
使用咬合垫预处理可显著改善 MM 和 VDO。
