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.

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.
