Oral Appliance Therapy for Sleep Apnoea

Oral appliance therapy — commonly referred to as a mandibular advancement device — is a recognised treatment option for obstructive sleep apnoea in selected patients.

Many patients exploring CPAP alternatives consider oral appliance therapy.

However, not all patients are suitable, and outcomes depend on careful case selection.

What is an oral appliance?

An oral appliance is a custom-made device worn during sleep that repositions the lower jaw forward. This can help maintain airway patency and reduce airway collapse in certain patients.

These devices are typically provided by clinicians trained in dental sleep medicine.

Who may benefit from oral appliance therapy

  1. Patients with mild to moderate obstructive sleep apnoea
  2. Individuals unable to tolerate CPAP
  3. Patients with specific anatomical characteristics
  4. Those seeking an alternative where clinically appropriate

Suitability cannot be assumed and requires structured clinical assessment.

When oral appliances may not be appropriate

Oral appliance therapy is not suitable for all patients.

In some cases:

  • The severity of sleep apnoea may limit effectiveness
  • Anatomical factors may reduce success
  • The underlying cause of airway obstruction may not respond to mandibular advancement

In these situations, alternative approaches — or no further intervention — may be more appropriate.

Why assessment is essential before treatment

Providing an oral appliance without structured assessment risks inappropriate treatment and suboptimal outcomes.

Before considering this therapy, it is important to:

Treatment should follow clear clinical reasoning, not assumption.

SleepLogic approach

SleepLogic provides structured reassessment for patients considering oral appliance therapy.

The focus is to determine:

  • Whether an oral appliance is appropriate
  • Whether alternative pathways are more suitable
  • Whether no further intervention should be pursued

This ensures treatment decisions are clinically justified.

Oral appliance vs CPAP

CPAP remains the most effective treatment for moderate to severe obstructive sleep apnoea. Oral appliances are typically considered when CPAP is not tolerated or in selected clinical scenarios.

The choice is not simply between devices — it depends on the individual patient and clinical context.

Sleep Strategy Assessment

If you are considering oral appliance therapy, the appropriate first step is structured reassessment.

The Sleep Strategy Assessment provides:

  • Review of diagnosis and prior treatment
  • Suitability evaluation
  • Clear recommendations

If you are considering an oral appliance for sleep apnoea, the next step is structured clinical evaluation — not immediate treatment.

This service is intended for patients with diagnosed obstructive sleep apnoea who have already attempted CPAP.
