目的:本研究旨在调查偏头痛患者(MG)组和对照组(CG)之间功能性咬合变量的可能差异。
方法:每组包括50名个体。进行仪器功能分析和数字咬合分析。检查的变量是从参考位置到最大切口的con突位移;关节隆起的陡度与对侧犬齿引导之间的角度差;关节隆起的陡度与同侧中央切牙引导和咬合面倾斜度之间的角度差。还研究了自我报告的磨削和咬合指数。
结果:两种临床评估的后髁突移位程度差异有统计学意义[MG:0.49mm(SD0.67mm),CG:0.29mm(SD0.27mm),p=0.012]和数字机械[MG:1.53mm(SD0.95mm),CG:0.9mm(SD0.66mm),p=0.001],关节隆起的陡度和对侧犬导向之间的角度差[MG:13.11°(SD8.33°),CG:9.47°(SD7.08°),p=0.021,MG:12.94°(SD8.71°),CG:9.44°(SD8.70°),p=0.017],和咬合面倾角[MG:11.16°(SD4.66°),CG:9.09°(SD4.37°),p=0.024]。自我报告的磨削(MG:39/50,CG:12/50,p<0.001)和咬合指数[MG:1.92(SD0.46),CG:0.21(SD0.66),p<0.001]在偏头痛患者中也明显更高。
结论:关节和咬合结构可能在偏头痛中起作用,因此应采用跨学科的方法加以考虑。
OBJECTIVE: This study aimed to investigate possible differences of functional occlusal variables between a group of migraine patients (MG) and a control group (CG).
METHODS: Each group included 50 individuals. Instrumental functional analysis and digital occlusal analysis were performed. Variables examined were condylar displacement from a reference position to maximum intercuspation; angular difference between the steepness of the articular eminence and the contra-lateral canine guidance; and angular difference between the steepness of the articular eminence and the ipsilateral central incisor guidance and occlusal plane inclination. Self-reported grinding and occlusal index were also investigated.
RESULTS: There were statistically significant differences in the extent of retral condylar displacement assessed both clinically [MG: 0.49 mm (SD 0.67 mm), CG: 0.29 mm (SD 0.27 mm), p = 0.012] and digital-mechanically [MG: 1.53 mm (SD 0.95 mm), CG: 0.9 mm (SD 0.66 mm), p = 0.001], the angular difference between the steepness of the articular eminence and the contra-lateral canine guidance [MG: 13.11° (SD 8.33°), CG: 9.47° (SD 7.08°), p = 0.021 and MG: 12.94° (SD 8.71°), CG: 9.44° (SD 8.70°), p = 0.017], and the occlusal plane inclination [MG: 11.16° (SD 4.66°), CG: 9.09° (SD 4.37°), p = 0.024]. Self-reported grinding (MG: 39/50, CG: 12/50, p < 0.001) and occlusal index [MG: 1.92 (SD 0.46), CG: 0.21 (SD 0.66), p < 0.001] were also significantly higher in migraineurs.
CONCLUSIONS: Articular and occlusal structures could play a role in migraine and thus should be considered in an interdisciplinary approach.
