Prediktivní faktory okluzních změn při léčbě obstrukční spánkové apnoe pomocí zařízení pro posun dolní čelisti (APNEAMOUVE)
Hodnocení prediktivních faktorů pro dentální okluzní změny při léčbě obstrukční spánkové apnoe pomocí mandibulárního předsunutého zařízení
This research addresses obstructive sleep apnea syndrome (OSAS), affecting 6-12% of French adults, often treated with mandibular advancement devices (MADs). MADs may lead to occlusal modifications, causing a 50% treatment abandonment rate. The study employs surface electromyography to assess masticatory muscle activity before and during MAD use, correlating it with occlusal changes after 6 months. The primary goal is to determine dental displacement profiles post-6-month MAD treatment, providing insights for personalized care and minimizing treatment failures.

Detailní popis
In this exploratory electro-pathophysiological study, our objective is to provide a significant contribution to understanding the underlying mechanisms of occlusal modifications associated with mandibular advancement device (MAD) treatment in patients suffering from obstructive sleep apnea syndrome (OSAS). Drawing from observational data, the researchers aim to identify specific electrophysiological profiles linked to masticatory muscle activity, correlating with occlusal changes after MAD treatment. This innovative approach involves detailed data collection on electrophysiological profiles, initial clinical characteristics pre-treatment, and post-treatment follow-up data. Focusing on patients from the dentistry department at Toulouse University Hospital, the study seeks to establish correlations between muscle activity recorded before and during MAD treatment and occlusal changes, ultimately defining electrophysiological patient profiles. These profiles could potentially guide personalized care, anticipating risks of occlusal modifications and reducing treatment dropouts or failures.
The study utilizes diverse exams-orthopantomogram, optical impressions, surface electromyography, polysomnography, and research questionnaires. Data collected pre- and post-mandibular advancement device treatment for six months will innovatively analyze the links between masticatory muscle activity and occlusal changes, aiming to define specific electrophysiological patient profiles.
In this research, participation in the protocol seamlessly integrates into routine care at the Odontology Department of the Toulouse University Hospital. The visits include the provision of the orthosis at 3 weeks (T1), with EMGs and digital occlusal analysis. The 6-week follow-up visit (T2) adjusts therapeutic propulsion, subjectively resolving symptoms related to OSAS. At the T0 visit, the researchers collect the polysomnographic monitoring before fitting the orthosis (carried out in the patient's reference sleep laboratory) to assess treatment efficiency.(The end-of-research visit (6 months after T0) comprehensively collects data, including questionnaires on stress, anxiety, sleep quality and quantity, oral habits, temporo mandibular dysfunction pain, and quality of life. Moreover, the researchers collect the polysomnographic monitoring after 3 months fitting the orthosis (carried out in the same patient's reference sleep laboratory than before fitting the orthosis).

OSA patients with mandibular advancement appliance
Patients with obstructive sleep apnea (OSA) treated with a mandibular advancement device (MAD), monitored for changes in masticatory muscle activity and occlusal modifications over a 6-month period. The study involves routine clinical visits and additional assessments including electromyography (EMG) with and without the appliance, optical impressions, digital occlusion recordings, patient diaries, and questionnaires on quality of life, temporo mandibular dysfunction pain, oral habits, stress and anxiety, and sleep evaluation. |

OCCLUSAL MODIFICATIONS AFTER 6 MONTHS OF OAM TREATMENT
Časové okno: 6 month
|
assessment of occlusal modifications after 6 months of mandibular advancement device (OAM) treatment. Dental occlusion will be measured using digital occlusal analysis with OCCLUSENS® (Bausch; Köln, Germany), considering the extent of contacts (centroid) and their intensity (%), and through morphometric analysis based on optical impressions obtained pre and post-treatment using the TRIOS optical camera (3Shape, Dentsply®) |

PRIMARY EXPOSURE VARIABLE: MASTICATORY MUSCLE ACTIVITY
Časové okno: 6 month
|
The primary exposure of interest is the activity of masticatory muscles measured by EMG, in the form of motor-evoked potentials (MEPs in µV/s). This measurement will be conducted at the T1 visit when the orthosis is provided to the patient (3 weeks after inclusion) and 6 months after the inclusion visit. At each measurement time, surface EMG will be conducted bilaterally (4 locations in total), both with and without OAM. The association between muscle activity at inclusion and occlusal modifications will be studied for the primary objective, while the association between muscle activity after 6 months of treatment and occlusal modifications will be explored as a secondary objective. |

Measured by the SF-36 questionnaire. Scoring the 36-Item Health Survey is a two-step process. First, all items are scored so that a high score defines a more favorable health state. In addition, each item is scored on a 0 to 100 range so that the lowest and highest possible scores are 0 and 100, respectively. Scores represent the percentage of total possible score achieved. In step 2, items in the same scale are averaged together to create the 8 scale scores. Items that are left blank (missing data) are not taken into account when calculating the scale scores. Hence, scale scores represent the average for all items in the scale that the respondent answered. |
