Background:
The stimulating palatal plate is an orthopedic device indicated for babies with Trisomy 21. A digital workflow should be implemented to enhance infant safety, starting by intraoral scanning and ending with device printing using a biocompatible material. Thus, the main objective of this technical note is to describe the digital workflow for fabrication of a palatal plate for therapy in T21 patients.
Material And Methods:
The fully digital linear workflow is presented below, as well as the effectiveness of use in a clinical case of an infant with T21. The maxilla was registered using the TRIOS3 intraoral scanner and the design process for the Stimulating Palatal Plate (SPP) aligns with similar parameters to craft an individual tray, using the Exocad software. After completion of the printing phase, the devices go through a crucial post-processing stage.
Results:
Upon placement, the SPP was perfectly adapted and the child with T21 presented immediate alteration of the tongue posture and lip sealing.
Conclusions:
The digital workflow from scanning to impression of the stimulating palatal plate is efficient and safe and should replace the conventional method, especially in patients with Trisomy 21. The printed plate presents excellent adaptation and acceptance by family members.
