Mandibular symphysis dimensions correlate with vertical skeletal patterns in adults, but not anteroposterior patterns. Further research on Gonion-Nerve measurements and skeletal patterns is recommended.
Area of Science:
- Orthodontics
- Cephalometric analysis
- Human anatomy
Background:
- Mandibular symphysis dimensions are crucial for morphological and orthodontic research.
- Understanding these dimensions aids in diagnosing and treating skeletal discrepancies.
Purpose of the Study:
- To investigate the relationship between mandibular symphysis dimensions and skeletal patterns.
- To differentiate associations based on anteroposterior and vertical skeletal classifications.
Main Methods:
- A cross-sectional cephalometric study of 90 untreated adult lateral cephalograms.
- Measurement of symphyseal height, thickness, and height-to-thickness ratio.
- Analysis of associations with seven anteroposterior and vertical skeletal parameters.
Main Results:
- Symphyseal measurements showed associations with SNAo (anteroposterior) in females and Gonial angle (vertical) in males.
- No significant differences in symphyseal dimensions were found based on anteroposterior skeletal classification (ANBo).
- Gonion-Nerve (mm) and Gonial angle significantly correlated with symphyseal height; Gonion-Nerve (mm), basal bone width (mm), and alveolar bone height (mm) correlated with symphyseal thickness.
Conclusions:
- Mandibular symphysis dimensions are significantly associated with vertical skeletal patterns, not anteroposterior patterns.
- Gonion-Nerve measurements warrant further investigation regarding their role in symphyseal dimensions and skeletal patterns.

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Introduction to the Skeletal System
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...
Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
Structural Joints: Fibrous Joints
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
