How an Anterior Deprogrammer can fail if used
The typical anterior deprogrammer
contacts the four lower incisors upon closure (1), thereby reducing
muscle contraction intensity and allowing a musculoskeletally optimal condylar
position. However, if used therapeutically, the canine can easily
occlude on the deprogrammer in an excursive movement (2), allowing
for near maximal temporalis contraction. With the condyle being slightly
translated, the disc is at serious risk of strain, compaction, and damage.
By simply modifying the deprogrammer (by removing
the portion of the deprogrammer that the canine occludes with (3)),
the occluding contact point returns to a lower incisor, thereby maintaining
suppression of contraction intensity and avoiding disc damage (5).
