Sleep Related Breathing Disorder

This study is evaluating two standard-of-care strategies used to prevent bite changes (occlusal changes) in patients treated with a Mandibular Advancement Device (MAD) for sleep-related breathing disorders such as obstructive sleep apnea (OSA). While MAD therapy is effective, it can lead to changes in how the teeth fit together, including the development of a posterior open bite. Participants in this study will be randomly assigned to one of two standard-of-care approaches: using an interocclusal aligner each morning after removing the MAD, or performing daily jaw exercises. Both methods aim to reduce the risk of occlusal changes. The study will follow participants over a 3-month period and includes dental evaluations, 3D oral scans, and short daily surveys. Findings from this research may help guide best practices for preserving occlusion during MAD therapy.

Mowat-Wilson Syndrome (MWS) is a rare syndrome characterized by the presence of facial gestalt and delayed psychomotor development, variably associated with intellectual disability, epilepsy, Hirschsprung's disease (HSCR) and multiple congenital malformations. Although there is evidence of the presence of dental and craniofacial anomalies in MWS, little epidemiological data is available to date. The goal of this observational study is to assess oral health and dento-facial phenotype of people affected by Mowat-Wilson Syndrome (MWS). In addition, the Oral Health Related Quality of Life (OHRQoL) will be investigated.
