The severe gummy smile and a skeletal class II profile pose challenges in treatment. This case report outlines an effective alternative for addressing these problems in a patient with skeletal class II division 2, class II molar relationship, retroclination of upper incisors, and lip protrusion. Treatment objectives included normalizing the overjet and overbite, improving the gummy smile, and establishing a satisfactory occlusion. A three-dimensional simulation was performed to consult with the patient, assess possible results, and predict treatment biomechanics. The treatment involved the use of two zygomatic and one inter-radicular temporary anchorage devices, along with botulinum toxin. After the 2-year follow-up, a satisfactory dental occlusion, aesthetic improvement, and adequate function were achieved. This approach offers a viable alternative to orthognathic surgery for adults with skeletal class II malocclusion and a severe gummy smile due to hypermobile lip.

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.

Article Synopsis
- A gummy smile is defined as showing more than 3 mm of gum tissue above the upper front teeth, and this study explored a new hyaluronic acid technique to reduce it.
- Fifty patients received the treatment, with evaluations conducted at various intervals for aesthetics, patient satisfaction, and side effects.
- Results showed a 2.5 mm average reduction in gum exposure after treatment, with 82.1% patient satisfaction, and 100% would recommend the procedure, while side effects like pain and bruising significantly decreased.
