An Anterior Deprogrammer reduces muscle contraction intensity and allowing for optimal condylar position (superior/anterior, musculo-
skelatally stable) by providing incisor contact only. |
An NTI-tss reduces muscle contraction intensity by providing and allowing for optimal condylar position (superior/anterior, musculo-
skelatally stable) by providing incisor contact only. |

| In an excursive movement, a mandibular canine can engage the Deprogrammer, thereby allowing intense temporalis contraction during translation of the ispilateral condyle, creating considerable joint strain. |
The contour of the Discluding Element of the NTI-tss is intended to reduce the possibility of canine occluding, thereby maintaining decreased muscular intensity and joint stability. (upper device shown. extreme excursion may allow for canine contact on the DE, in which case a lower device should be used. |

| Protrusive movement allows the incisors to engage the labial portion of the Deprogrammer, thereby allowing for potential joint strain. |
Protrusive movement maintains incisal edge contact on the DE, thereby maintaining sup-
pressed muscular intensity in all movements. |
