Temporary Anchorage Device Consideration for Malocclusion Treatment Plan Using Ricketts E-Line

Ricketts analysis is one of the measurements that aim for an ideal facial profile by drawing an E-line from the tip of the nose to the soft tissue of the pogonion. By evaluating the anteroposterior position of the lips using an E-line, an orthodontist could diagnose and plan the patient's treatment properly. To analyze the correlation of skeletal malocclusion with the position of the lower lip on the Ricketts esthetic line for Temporary Anchorage Device (TADs) placement consideration. The total sample was 127, class I and class II had 39 samples each, while class III had 49 samples. Analysis of the occlusal plane, growth direction, mandibular rotation, and lower lip was performed. Perform data analysis which is normality, descriptive, and Pearson correlation test. Pearson Correlation test results were divided into three groups. Ricketts aesthetic line (lower) correlated with FMA, SN-mandibular plane, FH-mandibular plane, Ricketts aesthetic line (upper), and gonion angle. Class II (FMA, Y-Axis, SN-Mandibular Plane, SN-Maxillary Plane, FH-Mandibular Plane, FH-Maxillary Plane, Angle of Convexity, Ricketts aesthetic line (upper)), and class III (FMA, Y-Axis, FH-Mandibular Plane, FH-Maxillary Plane, gonion angle, ANB, Ricketts aesthetic line (upper)) with a P-value of p> 0.01. The correlation between lower lip position with several variables in Class I, II, and III malocclusions can be helpful for the orthodontist to decide the angle that they should manipulate to achieve the ideal profile with the help of TADs.
