Introduction: This study investigates the anteroposterior (AP) positioning of maxillary central incisors in Gujarati females, emphasizing the role of soft tissue in orthodontic treatment outcomes. While the goal of orthodontic treatment is to achieve structural balance and functional efficiency, patient satisfaction often hinges on esthetic harmony.

Materials and Methods: A cross-sectional study was conducted with 100 adult females exhibiting aesthetically pleasing profiles. Posed smile photographs were taken to capture key facial landmarks, including Trichion, Glabella, Superion, and the Facial Axis (FA) point. Measurements were recorded for the distances from the FA point to the Goal Anterior Limit Line (GALL), Forehead Anterior Limit Line (FALL), and Glabellar Vertical Line (GVL). Statistical analysis was performed to assess the significance of these distances.

Results: The mean distances measured were 7.6±13.3 mm for GALL, 6.7±3.5 mm for FALL, and 8.2±3 mm for GVL, with an average forehead inclination of 9±3 degrees. GALL and FALL were found to be clinically significant (p-value = 0.000), while GVL was less significant (p-value = 0.243).

Conclusion: GALL and FALL are more clinically relevant landmarks for assessing the AP position of maxillary central incisors in Gujarati females, underscoring the forehead's importance in evaluating facial aesthetics.
