Fixed Prosthodontics The study formulates a standard of normalcy in an esthetic smile relative to: (1) Smile type (high, average, low); (2) Parallelism of the maxillary incisal curve with the lower lip (3) Position of the incisal curve relative to touching the lower lip (4) The number of teeth displayed in a smile. Open smiles were decided into three categories: A. High smile (S1): Reveals the total cervicoincisal length of the maxillary anterior teeth and a contiguous band of gingiva B. Average smile (S2): Reveals 75% to 100% of the maxillary anterior teeth and the interproximal gingiva only C. LOW smile (S3): Displays less than 75% of the anterior teeth Position of the incisional curve relative to touching the lower lip was divided into 3 groups: 1. (C1): The incisal curve of the maxillary anterior teeth touched the lower lip 2. (C2): The incisal curve of the maxillary anterior teeth did not touch the lower lip 3. (C3): The incisal portion of the maxillary anterior teeth were slightly covered by the lower lip A typical or average smile has the following characteristics: 1. The overall cervicoincisal length of the maxillary anterior teeth are displayed. 2. Gingiva does not show (except the interproximal gingiva). 3. The incisal curvature of the maxillary anterior teeth parallels the inner curvature of the lower lip. 4. The incisal curvature may be either totally touching or slightly touching the lower lip. 5. The six maxillary anterior teeth and the first or second premolars are displayed. 6. The midline coincides with a harmonious balance of the smile. 7. Stereotyped “feminine” & “masculine” tooth anatomy characteristics could not be related to the sample General notes: - The midline is the most important focal spot in an esthetic smile. 1 of 1
