Effectiveness of a Uniquely Designed Oral Appliance on Obstructive Sleep Apnea Control: A Pilot Study

Area of Science:

• Dental Sleep Medicine
• Orthodontics
• Respiratory Medicine

Background:

• Obstructive sleep apnea (OSA) is a chronic inflammatory disease requiring effective management.
• Oral appliances with mandibular advancement (OA_m) are an alternative therapy for OSA, particularly for patients intolerant to CPAP.
• Current OA_m designs often lack integration with skull structures, potentially limiting efficacy.

Purpose of the Study:

• To evaluate the effectiveness of a novel OA_m design (DIORS) that utilizes the Camper plane for reference in controlling OSA.
• To assess the impact of this unique OA_m on polysomnographic, cephalometric, and subjective patient data.

Main Methods:

• A retrospective longitudinal study of 33 OSA patients treated with the DIORS OA_m.
• Data collected included polysomnography, cephalometric measurements, and pre/post-treatment questionnaires.
• Statistical analysis involved descriptive statistics, Chi-square tests, generalized linear mixed models, and Pearson's correlation.

Main Results:

• Significant associations were found between the apnea-hypopnea index (AHI) and oxygen saturation, arousal index (AI), and heart rate.
• Cephalometric analysis revealed significant correlations between tongue posture, soft palate, hyoid bone position (C3), and airway dimensions.
• Hyoid bone position demonstrated a significant correlation with AHI and AI.

Conclusions:

• The DIORS OA_m, uniquely designed using the Camper plane for reference, proved effective in controlling OSA in this pilot study.
• This novel approach to OA_m design shows promise for improving OSA management.
