ORTHODONTIC REHABILITATION OF LOWER INCISOR -LATERAL CEPHALOMETRIC EVALUATION

Abstract

Lower incisor and its position in mandibular arch and in facial pattern are con­sidered to be particularly important when we establish orthodontic diagnostic and treatment plan. In our study, we aim to determine which dental and skeletal pattern are recurrent in orthodontic patients from urban area (Cluj Napoca, Romania) and correlate the data with lower incisor position and standard cephalometric values. An observational analytic longitudinal prospective study was conducted, based on lateral cephalograms. Cephalometric parameters analysed were: Interincisive Angle, FMIA, IMPA, ANB. The analysis of IMPA, revealed values that are greater than those considered to be the normal. In our study group, FMIA value was significantly and highly correlated with the interincisal angle (p<0.001, R=0.825). Also, the ANB value was significantly and moderately correlated with the IMPA (p=0.013, R=0.380). In conclusion, for evaluated group, angular values indicated a more protruding position of the lower incisors.
