Abstract

Objectives: To assess the symmetry of various cranial anthropometric points used as references for yaw orientation in the natural head position (NHP), relative to the mid-sagittal plane.

Materials and methods: A prospective analysis using tomography data from 55 patients was conducted. Radiopaque markers, placed on patients in NHP, facilitated head position recording in three planes, with subsequent digital transfer for orientation analysis. Symmetry of eight points (zygomaxillare, zygion, ectoconchion, frontozygomatic suture, stephanion, porion, mastoidale, condylion laterale) was measured against the mid-sagittal plane.

Results: Significant asymmetry was observed in the stephanion, frontozygomatic suture, and ectoconchion points (p < 0.05). No significant differences were found in the symmetry of other points (p > 0.05).

Conclusions: Findings suggest that stephanion, frontozygomatic suture, and ectoconchion are unreliable for yaw orientation in NHP. Other points, combined with clinical measurements, may offer better reliability.

评估自然头部位置偏航方向的颅骨地标：三维研究。

目的评估作为自然头位（NHP）偏航方向参考的各头颅人体测量点相对于中矢状面的对称性：使用 55 名患者的断层扫描数据进行前瞻性分析。在 NHP 患者身上放置不透射线的标记，便于在三个平面上记录头部位置，随后通过数字传输进行方向分析。以中矢状面为基准测量八个点（颧骨、颧弓、外髁突、前颧缝、阶状突、孔、乳突、侧髁突）的对称性：结果：在阶状突、前颧缝和外侧髁突点观察到明显的不对称性（P 0.05）：结论：研究结果表明，台阶腱、前颧缝和外侧颊骨对 NHP 的偏航定向并不可靠。其他点与临床测量相结合，可能会提供更好的可靠性。

期刊介绍： The journal Clinical Oral Investigations is a multidisciplinary, international forum for publication of research from all fields of oral medicine. The journal publishes original scientific articles and invited reviews which provide up-to-date results of basic and clinical studies in oral and maxillofacial science and medicine. The aim is to clarify the relevance of new results to modern practice, for an international readership. Coverage includes maxillofacial and oral surgery, prosthetics and restorative dentistry, operative dentistry, endodontics, periodontology, orthodontics, dental materials science, clinical trials, epidemiology, pedodontics, oral implant, preventive dentistiry, oral pathology, oral basic sciences and more.
