| The adjacent animation depicts four different occluding
schemes during
parafunction, each having considerable consequences: - Full intercuspation; - Ipsilateral non-working contact; - Canine only contact; - Contralateral working contact; Anterior midline point stop in centered and excursive
positions (as
demonstrated by an NTI device) allows for: When incorporated into occlusal therapy, the NTI device is not intended as the direct means of dictating an occlusal scheme. It serves to prevent the parafunctional activity and joint strain that makes for an unstable and un-reproducible jaw relationship. Following continual night use of the NTI, the resulting normalized muscular allows clinical recognition of any irregular occlusal contacts and allows optimal condylar seating and jaw relationship. |

| The
significant difference**
between a generic anterior deprogrammer (such as the Best-Bite)
and the NTI, is that the Discluding Element of the NTI is
specifically designed and modified by the dentist to prevent occluding
of the canine teeth in excursive parafunctional nocturnal
activity. (**click on the PowerPoint slide to advance its images) The graphic to the right shows how a canine contact on the deprogrammer can allow potentially destructive temporalis and superior lateral pterygoid intensity, thereby causing or perpetuating considerable damage. |

Although
many people have the ability to move their mandible a considerable distance excursively, they do not necessarily do so during parafunctional activity. However, those that do (not just can, but do) may develop the habit of clenching on the DE with a lower canine in excursive parafunctional activity. If the patient's symptoms can be reproduced by clenching on the DE with a lower canine, remaking the device on the mandibular incisors will dramatically decrease the intensity of the act by preventing a canine contact. |
