Background The enhancement of facial esthetics is one of the essential goals of orthodontic treatment. The concept of an excellent facial profile can differ between two individuals of the same population. Esthetics is a very vital component in Orthodontic diagnosis and treatment planning. Orthodontic treatment aims to achieve facial harmony by stabilizing the occlusion and pleasing facial and dental esthetics. Therefore, the characteristics of a pleasing, well-balanced face and a functioning occlusion should be evaluated. Aim This study aimed to determine preferable Antero-posterior lip positions in the Jaipur population and determine the range of anteroposterior lip positions as evaluated by orthodontists, patients, and professionals from a series of different lip positions in facial silhouettes, and compare their assessments. Materials and Methods The sample comprised 50 subjects (25 males & 25 females) from Jaipur. All angular and linear measurements were recorded for both males and females separately. The mean value of those readings was placed in NEMOTECH cephalometric software, and an average profile construction was done. This average profile will determine the lip fullness/ facial profile of males and females of the Jaipur (Rajasthan) population. A series of 7 profile silhouettes for males and seven profile silhouettes for females was developed by altering the lip positions (protrusion & retrusion in 2mm increments till 6 mm from the average profile) parallel to Frankfort horizontal plane (F-H) plane. Constructed facial silhouettes (seven male and female) were evaluated by (50) Orthodontists, (50) oral surgeons, general dentists (50), and non-specialists population (100). Evaluators were asked for the best profile in each gender from 1 to 7 in order of their preference. Result On calculating the standard deviation values, the profile selected as most favored for females is 2.33 by orthodontists, on the contrary, the standard deviation for Oral Surgeons, General Dentists & Non-specialists is 2.04, 2.14, and 2.12 respectively. It was found that profile retruded -2mm for males was the most favored, and profile retruded -4mm for males was second most favored. Average Profile /the profile without retrusion or protrusion was selected by orthodontists as the most favored profile. Profile retruded -2mm was the most favored profile for males clinically significant. It was found that profile retruded -2mm for females was the most favored, and profile retruded -4mm for females was second most favored. Profile retruded -2mm was the most favored profile for females by Orthodontists, General Dentists & non-specialists. Profile retruded -4mm was the most favored for females by Oral Surgeons. overall made insignificant. Conclusion The most favored facial profile is -2mm (profile 1) retruded lip posture in both males and females. According to Orthodontists most favored facial profile is 0mm (profile 6) average profile in males and -2mm (profile 1) retruded lip position in females. According to non-specialists most favored facial profile is -2mm (profile 1) retruded lip position in both males and females.
