Abstract :
During diagnosis and treatment planning of skeletal
malocclusions proper evaluation of sagittal jaw
relationship is an important step which is generally
determined by cephalometric analysis. Any cephalometric
analysis based on angular or linear measurement has
obvious shortcomings and limitation. The most commonly
used parameter is ANB angle which may vary since
Nasion being unstable with age questions the reliability of
ANB Angle as an indicator for apical base discrepancies.
Objective of The Study
The study evaluates the most reliable parameter for
assessing anteroposterior skeletal jaw relationship using
angular measurements and their correlation with visual
clinical examination.
Materials and Methods
Total of 60 Lateral cephalograms in Raichur
population, the cephalograms were grouped according to
visual clinical examination as follows • Group 1- Class I
(n=20) • Group 2- Class II (n=20) • Group 3- Class III
(n=20) Lateral cephalograms in each group were traced
and YEN angle, W angle, MKG angle and ANB angle
were measured.
Results
The study showed mean and standard deviation of
YEN angle was 119 + 6.76, MKG angle was 51.05 +4.94,
W angle was 52.28 +5.54 and ANB angle was 1.3 +2.67.
