Cephalometric Analysis
Review;Questions And Answers.
cephalometrics - answer;-uses a set of measurements from a lateral cephalometric
radiograph to evaluate a patient's face, teeth and skeleton. Information is available in
two planes of space: ANTEROPOSTERIOR and VERTICAL. The patient's individual
measurement are compared to standard measures available according to gender, age
and race (when available).
Cephalometric findings are used in coordination with other clinical findings and
measurements. They are used to "refine and improve clinical judgment and not to
displace it". A measurement that varies from the standard is not necessarily a problem.
Cephalometric findings provide quantitative information about craniofacial relationships
that may explain why specific clinical problems exists. A key principle in orthodontic
diagnosis is understanding that dental malocclusions that look similar at the clinical level
may be have quite different etiologies at the morphologic level. Cephalometric analysis
is a powerful tool in gaining knowledge and understanding of the soft tissue, skeletal
and dental relationships that are unique for each patient. - answer;-How are
