Smile Designing and Advancements

Smile design did not consider the natural irregularities and random deviations from the norm that contribute to the individuality and beauty of a person¿s smile. Most beautiful and natural smiles are not necessarily symmetric, uniform in color, or perfect by scienti¿c standards. Consequently, they maintain a natural intrinsic beauty not by the virtue of perfection but rather through the subtle beauty of imperfection. For these reasons, smile design guidelines that use a perfect model as a goal may not necessarily render the most beautiful and natural smile that satis¿es both thedentist and patient.The crafting of an ideal smile requires analyses and evaluations of the face, lips, gingival tissues, and teeth and an appreciation of how they appear collectively. Such an ideal smile depends on the symmetry and balance of facial and dental features. The color, shape, and position of the teeth are all part of the equation. Recognizing that form follows function and that the anterior teeth serve a vital role in the oral health of the patient is paramount. Using a comprehensive approach to diagnosing and treatment planning of esthetic cases can help achieve the smile that best.
