Condylar position may play a key role in the stability of orthodontic treatment of patients presenting with different skeletal patterns. The aim of the present study was to assess via cone beam computed tomography (CBCT) correlations between condylar position and sagittal skeletal relationship.
Condylar positions in CBCT images of 20 patients presenting with a Class I skeletal pattern, 20 with a Class II skeletal pattern, and 20 with a Class III skeletal pattern were evaluated retrospectively. The χ (2) test was used to assess the correlation between condylar position and sagittal skeletal relationships.
The condyles were anteriorly positioned in patients with Class II skeletal pattern in comparison with those with Class I and III skeletal patterns. No significant differences in condylar position between Class I and Class III subjects were detected.
A significant correlation between condylar position and sagittal skeletal patterns was observed in the present study. This relationship should be considered when planning and carrying out the appropriate orthodontic treatment for temporomandibular anomalies.
髁突位置可能在不同骨骼型患者的正畸治疗稳定性中起关键作用。本研究的目的是通过锥形束计算机断层扫描(CBCT)评估髁突位置与矢状面骨骼关系之间的相关性。
回顾性评估20例I类骨骼型、20例II类骨骼型和20例III类骨骼型患者CBCT图像中的髁突位置。采用χ(2)检验评估髁突位置与矢状面骨骼关系之间的相关性。
与I类和III类骨骼型患者相比,II类骨骼型患者的髁突位于前方。未检测到I类和III类受试者之间髁突位置的显著差异。
本研究观察到髁突位置与矢状面骨骼型之间存在显著相关性。在为颞下颌关节异常制定和实施适当的正畸治疗时,应考虑这种关系。
