简要总结
Obstructive Sleep Apnea (OSA) affects quality of life and health. Mandibular Advancement Devices (MAD) can help with OSA but may cause dental and jaw changes. This study uses a new 3D scanning method to track these changes and compare two adjustment methods for MAD to find the best approach for patients.
Goals:
- To track dental and jaw changes in OSA patients using 3D scans.
- To assess the impact of MAD on quality of life and cognitive function.
Study Details:
The aim of the study is to follow OSA patients at multiple centers over several years, comparing two MAD adjustment methods. Participants will undergo routine fitting and imaging.
Outcome:
The study aims to reduce dental and jaw changes and to improve MAD treatment and patient outcomes.
详细描述
Rationale: Obstructive Sleep Apnea (OSA) significantly reduces quality of life and increases the risk of severe health issue. While Mandibular Advancement Devices (MAD) are effective in managing OSA symptoms, they often introduce undesirable dental and skeletal changes, which can have a negative impact on patient satisfaction. Recognizing this issue, this study hypothesizes that using an innovative 3D superimposition technique to track these changes will allow to compare two different titration protocols more precisely and determine the optimal approach for various patient groups. By identifying the most effective titration protocol, the aim is to enhance treatment adherence and treatment success, addressing a critical gap in existing literature and significantly improving patient outcomes in OSA treatment.
Objective:
- Investigate dental and skeletal changes in OSA patients undergoing MAD treatment using an innovative 3D superimposition technique.
- Assess the impact of MAD treatment on quality of life (QoL) and cognitive function.
Study design: A prospective multicentre observational cohort study will be conducted, involving four screening points: at the study's onset and during the first, second, and third annual follow-up assessments. This investigation will involve two patient cohorts undergoing different titration approaches: orthodontic titration and another commonly used titration protocol.
Study population: The study will include adults with mild to moderate OSA who will undergo MAD treatment.

结局指标
主要结局
Dental occlusal measurements
时间窗: Baseline; Year 1; Year 2; Year 3
* Overbite (mm): the vertical overlap of the upper and lower teeth. * Overjet (mm): the horizontal overlap of the upper and lower teeth. * Maximal protrusion (mm): the most protrusive position of the mandible, independent of tooth contact. * Maximal retrusion (mm): the most retrusive position of the mandible, independent of tooth contact. * Protrusive range (mm): the distance between the most protrusive and most retrusive position of the mandible. * Maximal mouth opening (mm): the maximum distance between the upper and lower incisors when the mouth is fully opened.
Molar and canine relationships
时间窗: Baseline; Year 1; Year 2; Year 3
* Molar relationships (in premolar width equivalents): the relative position of the upper and lower molars. * Canine relationships (in premolar width equivalents): the relative position of the upper and lower canines.
