Side Effects of Two Different Mandibular Advancement Devices (MAD) in the Treatment of Snoring and Obstructive Sleep Apnea Syndrome (OSAS)

University Medicine Greifswald·interventional·Posted Aug 8, 2019·Updated Jun 15, 2023

In Brief

A clinical study evaluating H-MAD with a hinge system according to Herbst for Obstructive Sleep Apnea Syndrome and Temporomandibular Disorders. Completed, enrolled 65 participants across 9 sites.

Detailed Summary

Sleep-related breathing disorders (SBAS) are one of the most common causes of non-restorative sleep. Sleep therapy options include positive pressure ventilation with continuous positive airway pressure (CPAP) masks, mandibular advancement of the mandible with mandibular advancement devices (MAD), back restraining, weight reduction, ear, nose and throat surgical procedures, bimaxillary or mandibular remodeling osteotomies, and neurostimulation procedures N. hypoglossal. In mild to moderate obstructive sleep apnea syndrome (OSAS), MAD, back suppression and weight reduction are potential treatment options. This study aims to identify possible side effects in the temporomandibular system that occur during nocturnal support of a mandibular arch over two years. Two different MADs are compared in terms of construction, height (bite elevation) and protrusion mechanics: the H-MAD with an hinge system according to Herbst and the SomnoDent Fusion ™ MAD (called F-MAD) with sliding side wings. In addition, it is to be evaluated whether hinge system according to Herbst as a protrusion-controlling element and the reduction of the splint body for a reduced bite elevation leads to a significant reduction of side effects compared to the F-MAD.

Interventions

H-MAD with a hinge system according to Herbstdevice

The randomized grouping into blocks at a ratio of 1: 1 takes place over sealed envelopes containing the allocation key for the respective MAD. The assignment is stratified according to gender because gender is a strong predictor of sleep disorders and also temporomandibular dysfunctions Integration of the MAD (start of treatment) The laboratory-made MAD (F-MAD / H-MAD) is integrated and checked for a comfortable fit. The patient is instructed to always wear the splint during sleep. All patients receive an extended guide to jaw gymnastics with the instruction to do it in the morning after waking up and in the evening before falling asleep. Four weeks after incorporation, the titration phase begins, the slow adjustment of mandibular advancement to optimize sleep medical parameters while minimizing unwanted side effects. Control appointments take place after four weeks, six months, one year and two years after insertion of the MAD
