The Effect of Anterior Teeth Forms in Smile Esthetics

Abstract

Background and objective: Smile play a great role on the face attractiveness. A good-looking smile advances the individual's acceptability by affecting the social interactions. This study aimed to evaluate the effects of different anterior teeth forms on smile esthetics in people referred to dental faculty clinic in Ardabil, Iran.

Molar Incisor Hypomineralization: the use of Digital Smile Design (DSD) in the Esthetic and Functional Recovery of Teeth

“…For a moderate smile, the lateral incisors should ideally remain at the distance of 0.5-1.5 mm from the lower lip, whereas the central incisors and canines should be in close relationship with the lower lip line. 19 These characteristics were not observed in the present case. Young people usually display their upper teeth, so in this case, the patient's teeth should be lengthened.…”

“…The current socioeconomic and cultural point of view on esthetic standards establishes that people will be better accepted if their teeth are aligned in the arches, with a lighter color and harmonious contacts and contours. 19 The developmental disturbances of enamel are presented as structural anomalies that result from the action of various etiological factors during the enamel apposition and mineralization stages, leading to changes in shape, color, and contour of the teeth, and severely compromising esthetics. 1,8,12,23 Although the clinical characteristics may be similar, the etiological factors diverges.…”

“…In an esthetic smile, the incisal edges of the maxillary anterior teeth should follow a somewhat convex course that coincide with the curvature of the lower lip. 16,19 The incisal edge curvature should be parallel to and just above the level of the lower lip. For a moderate smile, the lateral incisors should ideally remain at the distance of 0.5-1.5 mm from the lower lip, whereas the central incisors and canines should be in close relationship with the lower lip line.…”

“…The excess of gingival tissue, in this case, was corrected using resective periodontal surgery techniques such as gingivectomy. 19 After 21 days following surgery, dental bleaching was used to achieve a lighter reference tooth color, aiming to provide the future restoration with a more natural appearance. 4,14,20 Thus, in order to soften the color difference between stained and healthy enamel, immediate external bleaching associated with home bleaching was performed.…”
