The Effect of Occlusal Forces on Healing Following Mucogingival Surgery ,

Nine adult mongrel dogs were used as experimental animals and divided according to occlusal function in the maxillary anterior region as follows: Group I—Unaltered occlusion, 2 animals, Group II—Hyperfunction, 3 animals; Group III—Hypofunction, 3 animals. One animal served as unoperated control. Hyperfunction was created using a cast gold overcontoured splint cemented on the mandibular anterior teeth so as to increase the vertical dimension and create excessive apico-labial forces (Fig . 1) . Hypofunction was created by extraction of the mandibular incisors (Fig . 2 ) .
