Overview
This lecture offers a comparative analysis of oral appliance therapy (OAT) using mandibular advancement devices (MADs) and hypoglossal nerve stimulation (HGNS/Inspire) in the management of obstructive sleep apnea (OSA). We will examine mechanisms of action, anatomical considerations, and clinical outcomes, including responder and non-responder profiles, based on current evidence. The session will also explore the role of combination therapy (OAT + HGNS) and present clinical cases that illustrate integrated, patient-centered treatment approaches.
Objectives

At the conclusion of this lecture, participants will be able to:

  • Identify anatomical factors and predictors of treatment success, as well as limitations, for both oral appliance therapy (OAT) and hypoglossal nerve stimulation (HGNS).
  • Evaluate clinical outcomes and responder criteria using evidence-based guidelines.
  • Review the importance of patient selection for achieving successful outcomes in combination therapy and analyzing clinical cases that demonstrate enhanced efficacy when OAT and HGNS are used together.
Target Audience
The target audience for this lecture is dental professionals, including general dentists, specialists, and clinicians interested in the management of sleep-related breathing disorders and orofacial pain.
