Partial Glossectomy as an adjunct to Orthodontic Treatment of Anterior Open Bite Associated with Macroglossia: A Case Report Tarun K Mittal Kulraj Achal James T Taylor Jay D Kindelan Dental Update 2024 14:1, 707-709.
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.
CPD/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
Article
The successful treatment of anterior open bite is dependent on accurate diagnosis and correction of the aetiology. The development of anterior openbite (AOB) is multifactorial in nature and may be due to dental, skeletal or soft tissue causes or a combination of these factors.
Incomplete eruption of anterior teeth may result in an anterior open bite. Should the patient have potential for further eruptive change of the incisors, then monitoring would be prudent. Failure of eruption of incisors may result from the presence of supernumerary teeth impeding the eruption of incisors or as a result of bony replacement resorption (ankylosis) secondary to dento-alveolar trauma. Treatment may involve orthodontic or surgical repositioning, alveolar distraction in conjunction with orthodontics or extraction and replacement of the anteriortooth.1
Digit-sucking habits can cause anterior open bite development by impeding vertical eruption of incisors.2,3 Should the habit persist into adolescence, the posterior teeth may overerupt into contact – there will then be little chance of spontaneous improvement of the AOB, even with cessation of the habit.4
