RESUMO
Background: There are many different types of malocclusions that may result from the sagittal, vertical, or transverse deviations in normal craniofacial development. When it comes to orthodontic problems, malocclusions in the sagittal plane may have a considerable impact on a person's self-esteem as well as their ability to speak and eat properly. Sagittal anomalies in the skeletal, dental, and soft tissue systems may now be accurately diagnosed using a universally accepted standard lateral cephalogram (SLCE). Methods and Materials: The principal investigator manually traced the cephalograms, identified skeletal landmarks, and measured the following data. The ANB angle (normal range: 0° to 4°) is the angle framed by the point A, Nasion, and B. Estimated oppositely from point A and B on the functional occlusal plane, with Wits evaluation: AO-to-BO direct distance. AB plane angle : the angle formed by the AB and the Npog plane (normal range = -9° to 0°). Beta angle: the angle framed by the A-CB and AB lines, with a typical range of 27° to 35°. W angle: this is the angle created by the opposite line from M to the S-G line and the M-G line, with a typical range of 51 to 55 degrees. The angle of convexity: the angle between N-point A and A-Pog. (Normal range: -8.5 to 10 degree). Results: We utilised Pearson correlation to see how well the different skeletal studies correlated with one another. Wits and the ANB angle of convexity exhibited an excellent relationship with each other, with r = 0.831 and Downs angle of convexity (both r = 0.823 and P = 0.01) being statistically significant. This study used Kappa statistics to assess the degree of agreement between several cephalometric diagnostic criteria. The agreement between the ANB and final groups was strong (k = 0.802, P = 0.01). Conclusion: There was a strong link between all of the cephalometric measures. The cephalometric landmark and valid indication was determined to be the most dependable in evaluating malocclusion and development pattern.
