Abstract: Orthodontic treatment of an anterior open bite is one of the most challenging malocclusions to treat, especially with respect to post-treatment stability. Complete diagnosis and targeted treatment is required for successful post treatment stability. In instances where macroglossia is the primary aetiology, partial glossectomy will greatly improve post treatment stability. The following case report describes a patient with severe anterior open bite and bimaxillary protrusion secondary to macroglossia. Treatment was successfully performed with partial glossectomy and straight wire orthodontics. Post-treatment relapse was minimal.

Clinical relevance: This article describes a review of the aetiology of anterior open bite and documents one possible treatment option, when the main aetiology of the malocclusion is of soft tissue origin
