CORRELATION BETWEEN THE FACIAL GROWTH PATTERN AND THE SMILE ARC IN MALE AND FEMALE PATIENTS IN THE DEPARTMENT OF ORTHODONTICS, SPECIALIST CLINIC OF DENTAL AND ORAL EDUCATION HOSPITAL, UNIVERSITAS AIRLANGGAIRA ANGGAR KUSUMA, VISKASARI PINTOKO KALANJATI AND ABDURACHMANAbstract In orthodontic, forming an aesthetic smile is important and should be achieved as the result of the treatment. One of the key factors should be considered to predict the smile arc (non-consonant vs. consonant) is the facial growth pattern of the patient (horizontal vs. vertical type, respectively). The consonant smile arc is considered as an aesthetic smile. Here we studied the correlation between the facial growth pattern and the smile arc of 56 males and 56 female patients by analyzing the pre-treatment SnGoGn angle (the Steiner method) and the curvature of the anterior maxillary teeth from the anterior facial photograph of each patient, respectively. Data were analyzed using chi-square (SPSS 17). We found that the contingency coefficients are 0.331 in female and 0.338 in male (p=0.2 and p=0.16, respectively). In this study we learn that there are positive correlations between the smile arc and the facial growth pattern both in female and male patients; the vertical facial growth pattern would produce a consonant smile, thus preferable as considered more aesthetic; while the horizontal face would likely have a non-consonant smile arc. These data may help the orthodontist to plan an individual treatment for each patient in order to have a beautiful smile.
