The three-dimensionality of the "gummy smile".

Abstract

The "gummy smile" is a complex developmental issue that requires a three-dimensional approach to diagnosis and treatment. This article explores the multifaceted nature of the gummy smile, tracing its origins to early childhood growth patterns and breathing dysfunctions. It emphasizes the importance of understanding the interplay between skeletal development, soft tissue function, and breathing modalities in the formation of craniofacial structures. The article discusses how early mouth breathing and tongue dysfunction can lead to maladaptive skeletal growth, resulting in vertical maxillary excess and other facial imbalances. It highlights the critical role of nasal breathing and proper tongue posture in promoting healthy craniofacial development. Treatment options are presented for both growing children and adults, ranging from preventive measures to surgical interventions. For children, the focus is on early intervention to redirect growth patterns, while for adults, comprehensive treatment may include orthognathic surgery to correct established skeletal discrepancies. By providing an in-depth analysis of the three-dimensional aspects of the gummy smile, this article aims to equip interdisciplinary teams with the knowledge needed for accurate diagnosis and effective treatment planning. It underscores the importance of addressing underlying causes rather than merely treating symptoms, promoting a holistic approach to patient care in aesthetic dentistry.
