About

This study evaluates the effect of the use of mandibular advancement devices (MAD) on dental occlusion and masticatory function during the first two years of obstructive sleep apnea (OSA) treatment.

52 participants diagnosed with obstructive sleep apnea will be studied, 26 will be treated with MAD and 26 participants will be treated with continuous positive airway pressure (CPAP) as a control group.

Participants will perform masticatory tests to assess masticatory performance in comminute and mixing capacity. Masticatory satisfaction perceived by the participants will be evaluated by questionnaires. Occlusal contact area and other occlusal characteristics will be assessed using occlusal silicone and T-Scan registrations and 3D digital models obtained with intraoral scan. Data collection will be performed before treatment with MAD or CPAP, and at 3, 6, 12, and 24 months from the start of treatment.

Full description

This prospective observational non-randomized clinical study aims to assess the effect of use MAD on masticatory performance. 52 subjects diagnosed with OSA will participate in this study divided into two different groups: 26 treated with MAD and 26 treated with CPAP. Data collection will be carried out before the start of treatment of the two modalities and at 3, 6, 12 and 24 months after starting the treatment. The intervention of the study will be based on execute chewing tests to evaluate masticatory performance from artificial food. Other aspects of matsticatory function would be also explored like subjective masticatory performance and jaw function limitation, dental position and occlusion, bite force or dental mobility. Artificial food tests will evaluate masticatory performance in comminute and mixing ability to determine the degree of reduction in masticatory performance produced by the use of MAD after 3 months of treatment. The main variable to be studied will be the median particle size of silicone tablets from Optozeta's test. This test is based on chewing 2 grams of silicone tablets inside a latex bag in order to evaluate their degree of comminution. The greater of grinded silicone, the greater of chewing performance. Another masticatory performance test will also be carried out is evaluation subject's mixing capacity with a two-colour chewing gum test. Degree of mixing of two colours of the gum will be checked after 40 chewing cycles. The more uniformity of the colour obtained, the more mixing ability the subject will demonstrate. A CPAP group control will be used, which will additionally allows us to know if this treatment has effects on dental position, occlusion and masticatory performance.
