하악골융기와 이갈이 및 교합의 연관성

Abstract

Purpose: The study was to elvaluate the association between torus mandibularis(TM), self-reported bruxism and occlusion. Methods: 212 patients with TM(TM group) and 302 patients without TM(control group) at Chosun university dental hospital from 1st Jan. 2019 to 30th Apr. 2019 were conducted. Self-reported bruxism, Angles's classification of upper and lower 1st molar occlusion and mandibular lateral movement(canine guidance, group function guidance) were investigated and compared stastically. Results: There was significant difference in the relationship between TM and self-reported bruxism in TM group(P<0.05). There was no significant difference in the relationship between TM and occlusion in each group(P>0.05) but, was significant difference in the relationship between TM and group function guidance in TM group(P<0.05). Conclusion: There was the association between TM, self-reported bruxism and group function guidance of mandibular lateral movement.
