Pages 471-477, Language: EnglishSalsench / Peraire / TorrentA 60-year-old man sought treatment for extensive tooth wear resulting from bruxism. He had no signs of temporomandibular joint dysfunction. The kinesiographic study revealed that he had a dual bite, with two intercuspal positions, separated by 3mm anteroposteriorly and by 7mm laterally. The dentition was restored with metal-ceramic crowns to restore a normal occlusion. The kinesiographic follow-up studies revealed that, initially, it was difficult for the patient to adapt to a new occlusal design, but 6 years later, the dual bite had disappeared. However the disoccluding angle had flattened where the second intercuspal position had previously existed, corresponding, clinically, to a change from canine guidance to anterior-canine guidance.
