cephalometric analysis: Definition, Indications, Uses, Aim, Objective of cephalometric analysis:

Definition: Evaluation and interpretation of both lateral and posteroanterior (PA) radiographs of the head (usually confined to the former).

Indications: When anteroposterior and/or vertical skeletal discrepancies are present; when anteroposterior incisor movement is planned in these cases.

Uses of lateral cephalometric analysis:

• To aid diagnosis by allowing dental and skeletal characteristics of a malocclusion to be assessed.

• To check treatment progress during fixed or functional treatments and to monitor the position of unerupted teeth.

• To assess treatment and growth changes by superimposing radiographs or tracings on reasonably stable areas: cranial base or its approximation (S-N line holding at S; anterior vault of the palate; Bjork’s structures in the mandible.

Aim: To assess the anteroposterior and vertical relationships of the upper and lower teeth with supporting alveolar bone to their respective maxillary and mandibular bases and to the cranial base.

Objective: To compare the patient to normal population standards appropriate for his/her racial group, identifying any differences between the two.
