Normal-Wear Replacement: What's Eligible
What normal functional wear and natural appliance aging mean, and how eligibility for replacement is determined.
How Appliances Age
A professionally prescribed oral appliance is used repeatedly during sleep and may experience gradual material wear and functional aging over time. This is a normal part of long-term appliance use.
What Counts as Normal Wear
Master Sleep 20™ provides protection when normal functional wear or natural appliance aging reaches a reasonable replacement threshold. Eligible deterioration may affect:
- Appliance fit.
- Retention.
- Structural integrity.
- Functional performance.
- Advancement components.
- Other clinically relevant appliance characteristics.
What Does Not Automatically Qualify
Normal cosmetic aging alone — such as surface discoloration that does not affect function — does not necessarily mean an appliance requires replacement.
Eligibility is determined based on the condition of the appliance and the treating dentist's evaluation.
How Eligibility Is Determined
The treating dentist evaluates the appliance and the clinical situation. When normal wear reaches an eligible replacement threshold, appliance replacement protection may apply.
The dentist then communicates with Master Sleep to coordinate the replacement on the patient's behalf.
