Abstract

Purpose: This observational study aimed to explore the association of various vertical skeletal and dentoalveolar components with the hypodivergence facial growth pattern in a Middle Eastern population.

Methods: A total of 320 lateral cephalometric radiographs of Middle Eastern adults were selected and divided, based on their vertical facial growth pattern, equally into two groups: 1) hypodivergent (GoGn/SN ≤ 28°) and 2) normodivergent (28° 

Results: Hypodivergence was primarily determined by the skeletal vertical components, while dentoalveolar components were less important. The main contributors were posterior facial height (S-Go) with 50.0% for males and 46.6% for females, anterior facial height (N-Me) with 47.0% for males and 45.9% for females, as well as the ramus length (Co-Go), ranging from 29.9 to 32.5% for males and 24.3% for females. There was no significant gender-related dimorphism in the evaluated cephalometric components.

Conclusion: The main contributing factors to hypodivergence were the skeletal mandibular components. Dentoalveolar heights contributed minimally to hypodivergence.

骨骼和牙槽齿垂直成分在面部发育模式中的作用：一项观察性研究。

目的：本观察性研究旨在探讨各种垂直骨骼和牙槽齿成分与中东人群面部发育模式的关系。方法：选取320张中东成人侧位头颅x线片，根据其面部垂直生长模式将其分为两组：1)低发散（GoGn/SN ≤ 28°）和2)无发散（28° ）。结果：低发散主要由骨骼垂直成分决定，牙槽骨成分不太重要。面部后高度（S-Go）占男性的50.0%，女性的46.6%；面部前高度（N-Me）占男性的47.0%，女性的45.9%；分支长度（Co-Go）占男性的29.9% ~ 32.5%，女性的24.3%。在评估的头颅测量成分中没有明显的性别相关的二态性。结论：下颌骨性成分是导致下颌低发散的主要因素。牙槽牙高度对低发散贡献最小。

期刊介绍： The Journal of Orofacial Orthopedics provides orthodontists and dentists who are also actively interested in orthodontics, whether in university clinics or private practice, with highly authoritative and up-to-date information based on experimental and clinical research. The journal is one of the leading publications for the promulgation of the results of original work both in the areas of scientific and clinical orthodontics and related areas. All articles undergo peer review before publication. The German Society of Orthodontics (DGKFO) also publishes in the journal important communications, statements and announcements.
