    1. 1. CEPHALOMETRIC ANALYSIS INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
    2. 2. ANALYSIS UTILIZING THE CEPHALOMETRIC TRACING 1) Describe the subject’s dento-facial morphology 2) Quantitative description of morphological deviations 3) Make diagnostic and treatment planing decisions 2) Evaluate change over time - treatment induced and growth process www.indiandentalacademy.com
    3. 3. Morphological Description Skeletal - horizontal and vertical Dental - horizontal and vertical Comparing individual subject’s tracing to the “ideal” Reference sample Cross-sectional Longitudinal - growth studies eg. Bolton-Brush, Ann Arbor and Burlington www.indiandentalacademy.com
    4. 4. Cephalometric Analyses Down’s Steiner’s Tweed’s McNamara’s OSU www.indiandentalacademy.com
    5. 5. Cephalometric Evaluation Identification of anatomic landmarks Landmarks: stable reference structures and maxillary and mandibular skeletal and dental Graphically relating the dento-facial elements to these reference structures Angular and or linear measurements www.indiandentalacademy.com
    6. 6. METHODS OF CEPHALOMETRIC ANALYSIS Two basic approaches Metric approach - use of selected linear and angular measures Graphic approach - “overlay” of individual’s tracing on a reference template and visual inspection of degree of variation www.indiandentalacademy.com
    7. 7. Metric Method - Use of selected linear and angular measures www.indiandentalacademy.com
    8. 8. Graphic Method - Use of a Composite Template www.indiandentalacademy.com
