AP relationship of the maxillary central incisors to the forehead in adult white males

Abstract

To evaluate and compare the anteroposterior relationship of the maxillary central incisors to the forehead in adult white males with harmonious profiles and in adult white male orthodontic patients. Methods: One hundred and one photographic images of adult white males with good facial harmony (control sample) were compared with 97 photographs of adult white males seeking orthodontic treatment (study sample). All images were of the face in profile with the maxillary central incisors and the forehead in full view. The images were imported into Adobe Photoshop™ and resized and rotated to the upright head position. Reference lines were constructed to assess the anteroposterior positions of the maxillary central incisors as well as forehead inclinations. Results: In the control sample, 91% had maxillary central incisors positioned between the FFA point and glabella, 8% posterior to the FFA point, and <1% anterior to glabella. In the study sample, 34% had maxillary central incisors positioned between the FFA point and glabella, 59% posterior to the FFA point, and 7% anterior to glabella. The difference between the means for the anteroposterior maxillary incisor position were statistically significant (P=0.0001). The positions of the maxillary central incisors were poorly correlated with the forehead inclination in the control, but not in the study group (r 2 =0.37 and r 2 =0.53 respectively). Conclusion: The forehead is an important landmark for anteroposterior maxillary incisor positioning for adult white male patients seeking improved facial harmony. your life and educational knowledge on to me and for your help with my research.
