Rationale: The effect of vertical dimension on sleep apnoea and respiratory variables in obstructive sleep apnoea patients.
Objective: To what extend should a possible worsening of the OSA condition, caused by an increase of mouth opening be taken into consideration in daily dental practice, when an occlusal stabilization splint (OSS) is placed in the mouth.
Study design: Cross over RCT-design Study population: OSA patients referred to ACTA from the Slotervaart Hospital, for treatment with a Mandibular Advancement Device (MAD), at least 18 years old.
Intervention: Occlusal stabilization splint (OSS) for the upper jaw and a controlled condition in a cross-over design Main study parameters/endpoints: Apnoea- Hypopnoea Index (AHI) and the Epworth Sleepiness Scale (ESS).
The aim of this study is to determine the effect of vertical dimension of OS on sleep and respiratory variables in OSA patients. The hypothesis is that insertion of an OSS and an increase of the vertical dimension will result in a significant increase in the AHI.
