Your patient says the sleep appliance isn't working, and you're out of easy answers

<p>You fit the mandibular advancement device six weeks ago. The patient came back last Tuesday and said it isn't working. Maybe they're still snoring. Maybe the Epworth score barely moved. Maybe the spouse is the one making the complaint, and the patient is fine. You're a general dentist running a restorative practice, and now you're triaging a sleep case in a 15-minute recall window that wasn't scheduled for sleep.</p><p>This is the failure state that the entire top-10 search result set ignores. Cleveland Clinic writes for the patient. Sleep-Doctor.com writes for the surgeon. The Reddit thread is a patient self-titrating with a Wesper home test because their dentist stopped answering. Nobody on that first page writes for the dentist holding the appliance and deciding what to do next.</p><p>The frustration compounds for the small DSO clinical director auditing appliance outcomes across 12 to 25 offices. Remake rates vary by location. One office is at 6%, another is at 22%, and nobody can tell you whether the delta is patient selection, bite registration technique, the lab's starting advancement default, or all three. Without a shared triage protocol, every office solves the same problem five different ways.</p><p>The pain isn't the appliance. The pain is the absence of a decision tree that isolates fit from titration from candidacy from lab-side fabrication defect, in that order, in the chair, in under 10 minutes.</p>

<p>Sleep appliance failure has five root causes, and they get confused with each other constantly. Cause one: wrong candidate. The patient has central apnea, severe OSA above AHI 30, or palate and epiglottic collapse patterns that a MAD cannot reach. Kent, Soose, and Rogers documented this failure mode in the August 2015 issue of Otolaryngology, Head and Neck Surgery. Drug-induced sleep endoscopy is the referral path, not another appliance.</p><p>Cause two, the most common: under-titration. The appliance is doing exactly what it was built to do at the starting advancement position, and it isn't enough. Ramar et al. 2015 (the AASM clinical practice guideline) sets the response criteria most dentists never see. Cause three: fit. Retention loss, occlusal contact errors, undercut blockout that wasn't done at the lab. Cause four: compliance, which is a data problem, not a clinical one, and DentiTrac or Braebon microsensors solve it in a week.</p><p>Cause five is the one nobody publishes: lab-side fabrication defect. Wrong bite registration transferred. Starting advancement set too conservative because the lab defaults to 60% protrusion on every case regardless of the patient's range. A PVS bite that distorted between the office and the bench. Connector fatigue at six months from an under-spec'd hinge. When the appliance failed because of the lab, no amount of chairside adjustment fixes it, and the remake decision is on you.</p>

<p>Dani Dental's sleep appliance workflow is built around a five-cause triage that dentists can run chairside before they call the lab. Send the case notes and the appliance to our sleep team and you'll have a written assessment back within 48 hours identifying whether the failure is titration (route to our titration protocol at /resources/sleep-appliance-titration-protocol), fit (chairside adjustment with documented steps), candidacy (referral back to the sleep physician for DISE), or fabrication (covered under our remake policy at /sleep-appliances/oral-appliance-remake-policy). Assen Dobrikov, the lab's clinical lead on sleep cases, signs the assessment personally, and you have his direct line on the report.</p><p>The lab-side differentiator is the intake. Every MAD case at Dani is built from a digital intraoral scan with a George Gauge or ProGauge bite registration, not a PVS bite that ships across a courier. Starting advancement is set to the patient's individual protrusive range from the scan, not a lab default. The Dobrikov family has been building removable appliances in Arizona since 1993 and in Sofia since 1988, and sleep appliances have been in the workflow since the FDA cleared MADs for OSA. Three generations on the bench, one bite protocol.</p><p>For DSO clinical directors, the standardization brief covers the single-lab partnership model: one starting advancement protocol, one bite registration technique, one remake threshold triggered automatically at the office level. That's the fastest lever on cross-office remake variance, and it's how the 10-to-30-office DSOs we work with move from four different vendors per region to one.</p>
