ClinConnect Summary

This clinical trial is studying ways to prevent changes in how your teeth fit together (called bite changes) when using a Mandibular Advancement Device (MAD). A MAD is a mouthpiece often prescribed to help with sleep-related breathing problems like snoring and obstructive sleep apnea (OSA). While MADs can improve breathing during sleep, they sometimes cause changes in your bite, such as gaps forming between your back teeth. This study compares two common methods to reduce these bite changes: wearing a special aligner after taking out the MAD each morning, or doing daily jaw exercises.

Adults who have been prescribed a MAD for sleep breathing issues and have most of their natural back teeth (with some exceptions) may be eligible to join. People with certain dental problems, past jaw surgery, or other specific health issues will not qualify. Participants will be followed for about three months, during which they will have dental check-ups, 3D scans of their mouth, and complete short daily surveys about their experience. The goal is to find the best way to protect your bite while still benefiting from MAD therapy.
