COMPARISONS
Flat plane splint vs anterior repositioning splint: which to prescribe
Flat plane splints treat bruxism and muscle pain by distributing occlusal load across a flat acrylic surface. Anterior repositioning splints reposition the mandible forward to decompress the TMJ, used for disc displacement with reduction.
THE BOTTOM LINE
Flat plane splints treat bruxism and muscle pain by distributing occlusal load across a flat acrylic surface. Anterior repositioning splints reposition the mandible forward to decompress the TMJ, used for disc displacement with reduction. Pick flat plane for nocturnal grinding and myofascial pain. Pick anterior repositioning for clicking joints and confirmed disc displacement. Dani Dental ships both in 5 business days with the technician's direct line on the case slip.
SIDE BY SIDE
Flat plane splint vs Anterior repositioning splint
| Consideration | Flat plane splint | Anterior repositioning splint |
|---|---|---|
| Primary indication | Nocturnal bruxism, myofascial pain, occlusal stabilization | Disc displacement with reduction, TMJ clicking, joint decompression |
| Mandibular position | Centric relation or maximum intercuspation | Protrusive, anterior to habitual occlusion |
| Arch typically used | Maxillary (mandibular acceptable) | Maxillary |
| Wear protocol | Nocturnal, indefinite | Full-time 6 to 8 weeks, then phased down |
| Risk of occlusal change | Low when worn nocturnally | Moderate; posterior open bite risk if worn too long |
| Bite registration required | CR or MIP record | Protrusive record at first comfortable click-free position |
| Dani Dental turnaround | 5 business days from scan or impression receipt | 5 business days from scan plus protrusive record |
| Remake rate (Dani Dental, 2025 YTD) | Under 2.5% across appliance category | Under 2.5% across appliance category |
| Patient compliance ceiling | High; nocturnal only | Lower; full-time wear is demanding |
THE TRADE-OFFS
Where each one earns its place
<p>The decision hinges on whether you are treating muscle or joint. Flat plane appliances unload the musculature and protect dentition. Anterior repositioning appliances mechanically recapture a displaced disc by holding the condyle forward. Mixing them up wastes 6 to 8 weeks of patient time and can introduce iatrogenic occlusal change.</p><p>Pick a flat plane splint when the patient presents with nocturnal grinding, masseter hypertrophy, generalized wear facets, or diffuse myofascial pain without joint noise. Choose an anterior repositioning splint when imaging or clinical exam confirms disc displacement with reduction, the click is reproducible, and you have a protrusive position where the click resolves. Opt for flat plane first when the diagnosis is uncertain; it is the lower-risk starting point and lets you reassess at 4 weeks.</p><p>Every Dani Dental splint ships with the fabricating technician's direct phone line on the case slip. If the protrusive record needs a second look or the acrylic needs an adjustment chairside, the technician who built it picks up. Response time on technician calls runs under 4 business hours.</p>
<p>Dani Dental fabricates both appliances in hard processed acrylic on a 5 business day turnaround from scan or PVS impression receipt. Pricing is published on the rx form; there is no procurement maze and no per-case quoting. The Dobrikov bench has been milling and processing occlusal appliances in Arizona since 1993, and the 2025 YTD remake rate across the appliance category sits under 2.5%.</p><p>Honest read: if your case is a dual-arch full-coverage orthotic for a complex TMD workup with multiple position records, a specialty TMD lab with an in-house gnathologist may serve you better. For the bread-and-butter flat plane and anterior repositioning splints that referring dentists prescribe weekly, Dani is built for the volume and the turnaround.</p>
