Prosthetic Rehabilitation with Amyloidosis of the Tongue.

Amyloidosis of the tongue can result in significant and irreversible alterations of tooth position and function due to prolonged application of imbalanced force on the teeth by the enlarged tongue. Due to the rarity of this oral form of systemic disease, little has been elucidated on management of the resulting impaired oral function. While surgery can address the size of the tongue, it carries significant morbidities, enlargement can recur, and does not address adverse tooth positioning. Prosthetic rehabilitation can more aptly restore oral function but it also needs to be tailored based on the patient's expectations and goals as well as biologic and mechanical parameters of treatment. This report discusses an effective and noninvasive application of a tooth-supported, removable prosthesis with an onlay occlusal design to restore occlusion, speech, and esthetics in a patient with tongue-based amyloidosis.
