目的颌面部形态和错牙合与最大咬合力(MOF)有关。虽然已有研究报道MOF与握力有关，但颌面部形态/错(牙合)与握力之间的关系尚不清楚。本研究旨在探讨颌面形态、错(牙合)与Hs之间的关系。选择年龄18~40岁的85例女性错(牙合)畸形患者，测量头影侧位片(SNA、SNB、ANB、下颌平面角、覆盖和覆盖)、同伴评定量表(PAR)指数和HS。受试者按日本正常头影测量平均值或各PAR指数测量项目中错牙合程度定义的参考值(小/低：平均值/参考值，大/高：≧平均值/参考值)进行分类。结果大角度组的HS明显低于小角度组。在小覆牙合或高横牙合(尖牙和磨牙的PAR指数显示反牙合/剪牙合)组中，大角度组的HS显著低于小角度组。在磨牙区有大弓角和小覆牙合或反牙合/剪牙合的受试者中，HS可能特别低。
Structured AbstractObjectivesMaxillofacial morphology and malocclusion are related to maximum occlusal force (MOF). Although it has been reported that MOF was related to handgrip strength (HS), the relationships between maxillofacial morphology/malocclusion and HS remain unclear. This study aimed to examine the relationships between maxillofacial morphology, malocclusion and HS.Setting and sample populationEighty‐five women with malocclusion, aged 18‐40 years, were selected.Materials and methodsLateral cephalometric radiographs (SNA, SNB, ANB, mandibular plane‐FH, and gonial angles, overjet and overbite), the Peer Assessment Rating (PAR) index and HS were measured. Subjects were classified by the Japanese normal mean value of cephalometric analysis or the reference value which was defined by degree of malocclusion in each PAR index measurement item (small/low: value < mean/reference value, large/high: value ≧ mean/reference value). Measurements were then compared between groups.ResultsHS of the large‐gonial angle group was lower than that of the small‐gonial angle group. In the small‐overbite group or high‐transverse (PAR index score showing crossbite/scissor bite in the canine and molars) group, HS in the large‐gonial angle group was significantly lower than that in the small‐gonial angle group.ConclusionsOur results suggest that gonial angle is the largest factor affecting HS. HS may be especially low in those subjects with a large gonial angle and a small overbite or a crossbite/scissor bite in the molar section.
