Cephalometrics aids in understanding dentofacial skeletal issues using Natural Head Position (NHP). Despite various methods, clinical application of NHP in orthodontic treatment remains challenging due to practical difficulties.
Area of Science:
- Dentofacial Orthopedics
- Cephalometric Analysis
Background:
- Cephalometrics provides insights into dentofacial skeletal problems.
- Natural Head Position (NHP) is a reproducible physiological function.
- NHP determination traditionally uses external horizontal or vertical reference lines.
Purpose of the Study:
- To review cephalometric methods for interpreting dentofacial skeletal problems.
- To highlight the role of Natural Head Position (NHP) in diagnosis and treatment planning.
- To discuss challenges in the clinical implementation of NHP.
Main Methods:
- Review of cephalometric reference planes (intra- and extracranial) for NHP determination.
- Analysis of diagnostic and treatment planning applications of NHP.
- Discussion of practical difficulties in applying NHP in clinical scenarios.
Main Results:
- Various cephalometric reference planes are utilized for NHP assessment.
- NHP is crucial for diagnosis and individualized orthodontic treatment planning.
- Clinical application of NHP faces significant practical challenges.
Conclusions:
- Cephalometrics offers valuable perspectives on dentofacial anomalies.
- Accurate NHP determination and application are vital for effective orthodontic treatment.
- Overcoming clinical implementation challenges is necessary for widespread NHP use.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
