Cephalogram in Orthodontics: Types, Uses, and Technique Explained
Write a short note on cephalogram.
Answer. A cephalogram is a radiograph showing the relation of cranial, facial, and dental structure taken in a standardized way.
Types of Cephalogram
“Importance of studying cephalograms for better orthodontic outcomes”
- Lateral cephalogram.
- Frontal cephalogram or anteroposterior cephalogram.
- Oblique cephalogram.
Lateral Cephalogram
This provides a lateral view of the skull. It is taken with the head in a standardized reproducible position at a specific distance from the source of the X-ray.
“Understanding the role of cephalograms in orthodontic treatment planning”
Frontal Cephalogram
This provides an anteroposterior view of the skull.
Uses of Cephalograms
- Its main use is in the formulation of orthodontic diagnosis by providing the dental, skeletal, and soft tissue relationship in the craniofacial region.
- It is very useful in predicting the growth of an individual.
- It also formulates the treatment planning, and the response to the treatment can be assessed before its beginning.
- Cephalograms help to assess the functional analysis.
- Growth of the skeleton of the face is assessed by the cephalograms.
“Common challenges in interpreting cephalograms effectively”
- A cephalogram is useful in estimating the facial type.
- A cephalogram is useful in growth prediction.
- Functional analysis can be carried out by a cephalogram.
- Cephalogram predicts the growth-related changes and changes that are associated with surgical treatment.
- Cephalograms are very useful in planning out the procedures in surgical orthodontics, such as skeletal repositioning.
- Cephalogram is a valuable aid in research work that involves the craniofacial region.
- Cephalograms are tangible records that are permanent, unlike other diagnostic measurements.
- Cephalograms are non-destructive and non-invasive and give proper information at relatively low cost.
- Cephalograms are very easy to store, transport, and reproduce.
“Role of counseling in clarifying cephalometric goals for patients”
Cephalogram Technique
- Cephalostat consists of two ear rods that prevent the movement of the head in the horizontal plane.
- Vertical stability is brought by an orbital pointer that contacts the lower border of the left orbit.
- The upper part of the face is supported by a forehead clamp positioned above the region of nasal bridge.
- Distance between the X-ray source and mid sagittal plane of the patient is fixed at 5 feet.
