What is the difference between a Herbst and TAP appliance?

For a referring dentist selecting a sleep appliance, the functional difference starts at retention strategy. The Herbst delivers mandibular advancement 24 hours a day because the patient cannot remove it, which makes it a common choice for non-compliant patients or adolescents requiring orthopedic correction alongside airway management. Fabrication involves cast metal framework, precision telescoping tubes, and cemented crown retention, so lab accuracy at the margin is not optional.

The TAP works on a single-point midline hook that threads through an anterior coupling. The patient turns a key to advance in 0.25 mm increments, which lets the clinician titrate over weeks until AHI improvement is confirmed on follow-up sleep data. Because the upper and lower trays are separate, the patient can open their mouth freely during the night, which many adults find more tolerable than a fixed device. Retention depends on the quality of the tray fit, so accurate impressions or digital scans translate directly into appliance comfort and efficacy.

Dani Dental fabricates both devices with same digital workflow: intraoral scan or PVS impression accepted, construction bite verified at the prescribed protrusive percentage before fabrication begins. Turnaround is 5 business days for TAP and 7 business days for Herbst. Dentists managing a mixed sleep caseload, general practitioners adding airway services or DSOs standardizing a sleep protocol across locations, receive a single-lab workflow that covers both device types without splitting vendor relationships.
