Assessment of the relationships among posture, maxillomandibular denture complex, and soft-tissue profile of aesthetic adult Korean women.
The objective of this study was to assess the relationships among the posture, the maxillomandibular denture complex, and the soft-tissue profile of aesthetic adult Korean women. From an initial group of 346 women, the authors examined 28 beautiful adult Korean women who had normal vertical and sagittal skeletal relationships and normal occlusion. There were no differences in the inclinations of the incisors to the occlusal planes in the maxilla and the mandible in the data for Korean women vs. Arnett's data for white women. However, the overbite and overjet in Korean women were slightly smaller than in white women. AB to maxillary occlusal plane angle (MxOP) represented the anteroposterior denture base discrepancy to the occlusal plane. Angulation of the maxillary occlusal plane to the Frankfurt (FH) plane and the true vertical line at submasale (TVL) (Sn) was a little steeper in Korean women than in white women. The FH plane was almost parallel to the true horizontal line in Korean women who had normal vertical and sagittal skeletal relationships and normal occlusion. With regard to soft-tissue variables, the upper lip length (Sn-Stms), interlabial gap, upper incisor exposure, nasolabial angle, lip and nose tip projection value, and TVL (Sn)-to-upper lip line (UL) angle showed interracial differences. The results of this study can assist in the diagnosis and treatment planning of orthognathic surgery.
