How is a sleep appliance sized?

A sleep appliance is sized from a bite registration plus upper and lower impressions or intraoral scans submitted by the referring dentist. The lab uses those records to fabricate a custom-fit device matched to the patient's arch dimensions, occlusion, and prescribed mandibular advancement, typically 60 to 70 percen...

THE SHORT ANSWER

THE FULL PICTURE

Why it works this way

Records the lab needs

Sizing a sleep appliance starts with the clinical records the referring dentist submits. For Dani Dental's sleep workflow, that means full-arch upper and lower scans (or PVS impressions), a centric bite, and a protrusive bite registration set at the dentist's prescribed advancement position. The protrusive bite is what determines mandibular positioning in the final device; without it, the lab cannot size the appliance correctly.

What bite registration does Dani Dental need for a sleep appliance?

A protrusive bite registration taken at 60 to 70 percent of the patient's maximum protrusive range, captured with a George Gauge or equivalent tool. We also need a centric bite plus full-arch upper and lower records (scans or PVS impressions). The protrusive bite is non-negotiable: it sets the starting mandibular position the appliance will hold. If the protrusive registration is missing or unclear, the case pauses until the office confirms the target position.

Can a sleep appliance be made from a digital scan?

Yes. Dani Dental accepts intraoral scans from all major scanners (iTero, Trios, Primescan, Medit) for sleep appliance cases. The dentist scans the upper arch, lower arch, centric bite, and the protrusive bite at the prescribed advancement position. Digital records typically cut turnaround by 3 to 5 days versus PVS impressions because there is no shipping or model pour step. The fit accuracy on milled and printed sleep devices from digital records meets or exceeds traditional fabrication.

How long does a custom sleep appliance take to fabricate?

Standard turnaround at Dani Dental for a mandibular advancement device is 10 to 14 business days from the date complete records arrive in lab. That covers design, fabrication, finishing, and QC review. Rush timelines are available case-by-case when the referring office calls ahead. Cases missing the protrusive bite or with unclear records add days while we resolve the gap, which is why we review every sleep case at intake and call the office same-day if anything is off.
