[Perfecting smile esthetics: keep it pink!].

INTRODUCTION

Smile aesthetics is based on numerical, physical, physiological and psychological data regarding beauty, while taking into account the desires of the patient. It is determined by the shape, colour and position of the lips, teeth and gingival tissues. Periodontal examination in both the facial and labial settings supports analysis of the gingival display during natural and forced smiling, the health of the periodontium, the gingival contours, the aesthetic gingival line, and the presence of the papillae.

MATERIALS AND

METHODS

All these data will help establish a gingival aesthetic score to determine the causes of disharmony and possible treatment.

DISCUSSION: During implementation of the global orthodontic treatment plan, periodontal plastic surgery can change the gingival appearance and morphology in order to restore the harmony of the smile. Subtractive periodontal plastic surgery treats biological space defects and excess tissue during incomplete passive eruption by gingivectomy or apically positioned flap, combined, or not, with osteoplasty or osteoectomy. Finally, injections of hyaluronic acid in the papillae can plump them up and minimize the size of any black holes.
