Abstract

Background: Mandibular advancement devices (MADs) are an effective treatment for obstructive sleep apnoea (OSA), though individual responses to therapy can vary.

Objectives: This study aims to: (1) examine how craniofacial characteristics are associated with MAD effectiveness to refine patient selection and improve outcomes; and (2) assess the association of skeletal facial patterns with treatment efficacy and mandibular advancement.

Methods: This retrospective study used data from a previous quasi-experimental study. Analysis was conducted with two-piece adjustable devices, following a standardised protocol. K-means clustering analysis categorised the sample into subtypes using clinical, polysomnographic, and anatomical data to evaluate MAD treatment response. Patients were also classified by growth pattern, and treatment response and mandibular advancement were compared across facial patterns.

Results: The study included 112 patients. Of these, 41 patients (36.61%) were assigned to Cluster 1 and 71 patients (63.39%) to Cluster 2. Cluster 1 patients had more severe OSA, with higher ESS, BMI, T90%, and AHI, along with a vertical facial pattern and narrower airways. Treatment response rates were significantly lower in Cluster 1 compared to Cluster 2. Among facial pattern groups, 32 patients were hyperdivergent, 46 were neutral, and 34 were hypodivergent. The responder rate was significantly lower in the hyperdivergent group, indicating reduced treatment effectiveness.

Conclusions: This study suggests that the efficacy of OSA treatment with MADs may be associated with anatomical subtypes. Cluster 1 patients showed a lower response rate compared to Cluster 2. Additionally, patients with hyperdivergent patterns may have a less favourable response to MAD treatment.

期刊介绍: Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function. Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology. The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
