Proposal of a New Therapeutic Classification in Gingival Smiles Focused on Treatment with Semi-Permanent Infiltrations Angulo Manzaneque, Gema Baus Domínguez, María Ruiz de León Hernández, Gonzalo Serrera-Figallo, María de los Ángeles Sánchez Aguilera, Fátima Torres Lagares, Daniel gummy smile treatment classification A gummy smile, defined as excessive gingival exposure while smiling, is an esthetic and functional condition affecting an individual’s quality of life. Despite its prevalence and impact, the classification and treatment of the gummy smile remain challenging in clinical practice. The problem lies in (1) the fact that the etiology of this pathology is multifactorial, and these factors sometimes go unnoticed, (2) the lack of consensus on the classification criteria, which, together, create (3) challenges in designing an optimal treatment plan for each patient. This article reviews the etiologic factors of this condition as the main basis for understanding the existing classifications of the gummy smile. It highlights the importance of muscle dynamics in the genesis and treatment of this clinical condition. We present a new, treatment-oriented classification that integrates the muscle hyperactivity present within the classification criteria and explore the implication of this interaction in the design of effective treatments. The ultimate goal of this present work is to improve the clinical understanding of the gingival smile and offer more personalized treatment strategies, through a more complete classification. 2024-11-05T11:21:12Z 2024-11-05T11:21:12Z 2024-10-05 journal article Angulo Manzaneque, G. et. al.
