 The Superior alternative to bite guards
The NTI-tss
Plus™ does the job of a bite guard, but covers only
the front teeth. The NTI-tss Plus is a small, clear, "taco shell" shaped appliance.
Attached on the incisal edge of the shell is an anterior-posterior
discluding element (DE) that provides for a point stop on the mesial-incisal
edges of the two opposing central incisors.
The NTI-tss therapeutic protocol was developed by James P.Boyd, DDS. The NTI-tss Plus is the only lab-produced, customizable alternative to the chairside NTI-tss. Originally developed to prevent migraine pain, the NTI-tss Plus is proven to be a superior alternative to full-coverage bite guards.
 FDA approved
The NTI-tss protocol is approved for the Prevention of Medically Diagnosed Migraine Pain and Jaw Disorders through the reduction of trigeminally innervated muscular activity.
More effective
Full-coverage bite guards increase clenching activity for some patients by providing an ideal clenching surface for canines and molars. The NTI-tss Plus discludes all posteriors and reduces clenching intensity by nearly 70%.
More comfortable, better compliance
The NTI-tss Plus is smaller, less bulky and won't trigger a gag reflex. Because it is more comfortable, patients actually wear it.
Less chair time, easier to seat
Because the NTI-tss Plus covers only the front teeth it's easier to seat, saving you valuable chair time.
durable, precise fit
NTI-tss Plus is made from Keller's Clear 450® thermoplastic material. Our high heat, high pressure injection process guarantees a perfect fit with proven durability. Clear 450 provides a perfect fit with no shrinkage and won't absorb stains or odors. Clear 450 is proven to last three times longer than conventional acrylic guards.
upper or lower?
Although some doctors still prefer the maxillary NTI-tss Plus, more experienced users continue to find additional indications for a lower appliance. Factors that influence arch choice may include clinical crown length and tooth contour (retention), tooth rotations and malposition, uneven incisal edges, and narrow arch width. Your Keller technical advisor can make recommendations after models are mounted and analyzed in the laboratory.
What does the lab need to fabricate the device?
- Full arch models or VPS impressions
(We recommend Alginot™ from Kerr or Position™ Penta™ from 3M)
- Maximum Protrusive Measurement
What is the recommended insurance code?
All plans are different so coverage varies. In general the same insurance codes for splints, TMJ appliances, habit appliances all apply to the NTI-tss Plus™.
*Please note: Keller Laboratories certifies that Clear 450® does not contain Bisphenol-A.
