摘要/Abstract

摘要： 目的：通过研究成年及未成年偏颌患者平面横向倾斜度与双侧颞下颌关节间隙的相关性,探讨平面横向倾斜度与下颌骨位置的关系,为此类患者的临床治疗提供参考。方法：选择40例偏颌患者的CBCT影像（成年患者20例,未成年患者20例）,应用Invivo5软件进行三维重建。分别测量上颌双侧自尖牙至第一磨牙平面的横向倾斜度及垂直高度,计算双侧同名牙的垂直高度差。测量双侧颞下颌关节的前、上、后间隙。采用SPSS 17.0软件包对平面横向倾斜度与双侧颞下颌各关节间隙的相关性进行统计学分析。结果：未成年组平面横向倾斜度与偏斜侧颞下颌关节上间隙存在负相关性（P<0.05）,其双侧尖牙高度差值与偏斜对侧关节前间隙存在负相关性（P<0.05）。成年组平面横向倾斜度及双侧同名牙高度差与偏斜侧、偏斜对侧的颞下颌关节各间隙无显著相关性（P>0.05）。结论：偏颌患者平面横向倾斜度在偏颌早期与其下颌骨位置有一定相关性,早期矫治偏颌畸形对预防其发展成严重骨性偏颌有重要意义,治疗时平面横向倾斜度的纠正不容忽视。

Abstract: PURPOSE: To investigate the correlation between the occlusal canting and the bilateral temporomandibular joint (TMJ) space in adult and juvenile mandibular deviation patients and study the mutual influence between the occlusal canting and mandibular position, in order to provide references for clinical treatment. METHODS: CBCT data of mandibular deviation patients（20 adults,20 juveniles）were selected. Inivo5 Dental Anatomage software was used to reconstruct the structures. The occlusal cant and vertical height of the bilateral maxillary from canines to first molars were measured, and the vertical heights difference between the same teeth on both sides was calculated. The anterior, superior and posterior space of temporomandibular joint were measured respectively in both groups. Pearson correlation analysis between the occlusal canting and bilateral condylar space was carried out by using SPSS 17.0 software package. RESULTS: In the juvenile group, negative correlations were found between the occlusal cant and the superior TMJ space on the deviated side (P<0.05). Negative correlation was found between the vertical height difference of bilateral canines and the anterior TMJ space on the deviated side in the juvenile group(P<0.05). In the adult group, no significant correlation was observed among those correlated examination (P>0.05). CONCLUSONS: The occlusal canting is moderately correlated with mandibular position in the early stage of mandibular deviation patients. Early treatment of mandibular deviation is of great importance in preventing its progression into severe skeletal malocclusion, and more attention should be paid on the correction of the canted frontal occlusion plane.
