Cephalometric Analysis Flashcards

1
Q

Consist on tracing points on acetate paper and from these points the desired angular and linear values are measured to obtain a concise and understandable description of the craniofacial pattern and classify the patient, this is going to helps us to identify what the objectives of the study will be, choose the treatment modality and predicting its success.

Describe what are some of the most importante thigs that we can see in the extraoral pictures that can be helpful for the orthodontic diagnosis:

((FSSymStPmDevRe))

A

facial shape,
symmetry,
soft tissue harmony and
the state of the perioral muscles.
This determines deviations from normal with respect to a patient’s sagittal, vertical, and transverse maxillofacial relationships and
evaluates the relationship of the dentition and facial structures.
