Condylar guidance can be determined using the clinical and radiographic methods. The present study was conducted to determine condylar guidance using the protrusive interocclusal wax method, panoramic radiographs, and lateral cephalogram.
The aim of the study was to compare the correlation between sagittal condylar guidance with protrusive interocclusal method, panoramic radiographs, and lateral cephalogram.
The present study was conducted on 82 dentulous subjects (males 41, females 41). In all subjects, interocclusal registration values and condylar guidance values were measured using panoramic radiographs and lateral cephalograms.
The mean ± SD protrusive interocclusal registration value on the left side was 34.01 ± 1.2 mm and 34.08 ± 1.4 mm on the right side. The panoramic radiographs showed 35.12 ± 1.6 mm on the left side and 35.16 ± 1.7 mm on the right side. The mean ± SD protrusive interocclusal registration values on the left side was 34.01 ± 1.2 mm on the left side and 34.08 ± 1.4 mm on the right side. Lateral cephalogram showed 34.35 ± 1.3 mm on the left side and 34.67 ± 1.6 mm on the right side. There was a significant difference between the methods ( < 0.05).
Sagittal condylar guidance can be evaluated using protrusive interocclusal method. Along with it, other methods such as panoramic radiographs and lateral cephalogram may also be used for recording condylar guidance.
Lateral cephalogram and panoramic radiographs may be reliable in determining condylar guidance, which can be used in orthodontic treatment planning.
髁突引导关系可以通过临床和影像学方法来确定。本研究旨在通过前伸牙合间蜡记录法、全景片和侧位头颅定位片来确定髁突引导关系。
本研究旨在比较前伸牙合间蜡记录法、全景片和侧位头颅定位片与矢状向髁突引导关系的相关性。
本研究共纳入 82 名有牙颌患者（男 41 名，女 41 名）。所有患者均采用全景片和侧位头颅定位片测量牙合间记录值和髁突引导关系值。
左侧前伸牙合间记录值的平均值 ± 标准差为 34.01 ± 1.2mm，右侧为 34.08 ± 1.4mm。全景片显示左侧为 35.12 ± 1.6mm，右侧为 35.16 ± 1.7mm。左侧前伸牙合间记录值的平均值 ± 标准差为 34.01 ± 1.2mm，右侧为 34.08 ± 1.4mm。侧位头颅定位片显示左侧为 34.35 ± 1.3mm，右侧为 34.67 ± 1.6mm。各方法之间存在显著差异（<0.05）。
前伸牙合间记录法可用于评估矢状向髁突引导关系，此外，还可以使用全景片和侧位头颅定位片等其他方法来记录髁突引导关系。
侧位头颅定位片和全景片在确定髁突引导关系方面可能具有可靠性，可用于正畸治疗计划。
