Combined Conventional-Digital Workflow to Fabricate a Palatogram for Speech Rehabilitation in a Single Arch Completely Edentulous Class II Patient With Dysarthria: A Clinical Report

Abdulaziz M Alqarni et al. Case Rep Dent. .

Abstract

This clinical report describes the creation of a palatogram for speech improvement in a single-arch, completely edentulous, skeletal Class II patient with dysarthria. The treatment focused on occlusal considerations specific to Class II denture wearers and capturing the tongue-palate contact regions during speech. The outcome was assessed by consulting a speech therapist using speech analysis software.

Keywords: complete; denture; dysarthria; palate; software; speech; tongue.

(a) The palatogram with trial denture serves as a preparation scan (the purple denture) in the 3Shape Dental System. This helps with waxing up the palatal surface of the denture, while the trial denture helps to set the teeth. (b) The trial denture (gray in color) serves as an occlusal rim and a guide for tooth positioning.
