Abstract

Cephalometric evaluations of the skeletal pattern of 30 patients with anterior open-bite malocclusion were compared to those of 30 individuals with a normal overbite. The posterior/anterior face height ratio (PFH/AFH) was the only skeletal characteristic statistically different in the two groups. The other cephalometric measurements were not found to be statistically different in the malocclusion and normal overbite groups (SN-GoGn, SN-PP, gonial angle, LFH/AFH ratio), indicating that there is no skeletal origin in the group with anterior open-bite in this study.

摘要

对30例前牙开颌错颌畸形患者的骨骼形态进行头影测量评估，并与30例正常覆牙合个体的测量结果进行比较。两组之间唯一有统计学差异的骨骼特征是后/前面部高度比（PFH/AFH）。在错颌畸形组和正常覆牙合组中，未发现其他头影测量值有统计学差异（SN-GoGn、SN-PP、下颌角、LFH/AFH比值），这表明在本研究中，前牙开颌组不存在骨骼来源问题。
