Abstract

IntroductionA gummy smile (GS) affects the esthetic and the psychological status as it usually decreases the self-confidence leading to hidden or controlling the smile. A smile with more than 2 mm exposed gingiva is called gummy smile. It may be due to one or more of the following etiologies; altered passive eruption of teeth, dentoalveolar extrusion, vertical maxillary excess, and short or hyperactive lip muscles. The treatment of gummy smile should be planned according to its cause/causes. The purpose of this case report was to highlight the ability of combined treatment of gingivectomy and Botox injection technique in managing a severe gummy smile. Also, techniques, advantages, disadvantages, indication and contraindications of Botulinum toxin (BT) are discussed at the literacy. Presentation of the caseA 24 year old female patient with a severe gummy smile was refereed to the periodontal clinics of our institution. Clinical examination revealed that she has a GS of an 11–12 mm gingival exposed area that was indicated for orthognathic surgery. The GS was treated by a gingivectomy surgery to increase the clinical crowns of upper anterior teeth and the use of Botox injections. The treatment showed remarkable and satisfactory results instead of doing extensive surgery. Discussion and conclusionIt is important to assess the patients’ esthetic expectations and show the possible therapeutic solutions that fit him. We revealed that BT is considered as one of the minimally invasive, quick and affordable modalities that can replace extensive surgical procedures for corrections of sever GS.
