Abstract

Objective: The purpose of this study was to analyze and compare the differences in chewing efficiency among patients with different vertical skeletal types of Angle Class I and Angle Class II malocclusions, to provide reference for orthodontic clinical practice.

Method and materials: Sample size estimation revealed a minimum of 53 for each class. Thus, a total of 108 patients with Angle Class I and Angle Class II malocclusions were selected. Lateral skull radiographs were taken, and head measurements were analyzed via geometric tracing software. Chewing efficiency was measured using the gravimetric method to compare between the two groups. The vertical skeletal pattern was classified via Steiner analysis.

Results: Significant statistical differences in chewing efficiency were observed between patients presenting with Angle Class I and Angle Class II malocclusions (P < .05). Additionally, significant differences in chewing efficiency were observed among patients with different vertical skeletal patterns (P < .05). Furthermore, a statistically significant difference in chewing efficiency was found between men and women (P < .05).

Conclusions: Patients with Angle Class I malocclusions exhibited significantly higher chewing efficiency compared to those with Angle Class II malocclusions. Among patients with different vertical facial types, the chewing efficiency followed the order of low angle > normal angle > high angle. Moreover, men demonstrated a higher chewing efficiency than women.

对具有不同垂直骨骼模式的角度一类和角度二类畸形患者的咀嚼效率进行比较研究。

研究目的本研究旨在分析比较不同垂直骨骼类型的角I类和角II类错合患者在咀嚼效率上的差异，为正畸临床实践提供参考：样本量估算显示，每个等级的样本量至少为 53 个。因此，共选取了 108 名角度Ⅰ类和角度Ⅱ类错颌畸形患者。拍摄头颅侧位X光片，并通过几何追踪软件分析头部测量结果。使用重力法测量咀嚼效率，比较两组患者的咀嚼效率。通过斯坦纳分析法对垂直骨骼模式进行分类：结果：角一期和角二期畸形患者的咀嚼效率存在显著的统计学差异（PConclusions：本研究显示，与角度II类畸形患者相比，角度I类畸形患者的咀嚼效率明显更高。在不同垂直脸型的患者中，咀嚼效率依次为低角度>正常角度>高角度。此外，男性的咀嚼效率高于女性。

期刊介绍： QI has a new contemporary design but continues its time-honored tradition of serving the needs of the general practitioner with clinically relevant articles that are scientifically based. Dr Eli Eliav and his editorial board are dedicated to practitioners worldwide through the presentation of high-level research, useful clinical procedures, and educational short case reports and clinical notes. Rigorous but timely manuscript review is the first order of business in their quest to publish a high-quality selection of articles in the multiple specialties and disciplines that encompass dentistry.
