The greatest dimensional changes of addition and condensation silicone impressions appear in the first hour after their separation from the model.

The study conformed the validity of irreversible occlusal therapy (selective grinding) in patients with TMD.

The results of this investigation point to significant prevalence of craniomandibular disorders in the examined population group. The incidence of TMJ and masticatory muscle pain in 4% of examined persons and of pain during mandibular movements only in 1% of examined persons, points to presence of mild or initial types of CMD in this population group.

In patients with mandibular prognathism where enormous mandibular growth was the main causal factor of the deformity, the sagittal split ramus osteotomy yielded good results. The rigid fixation of bone fragments and reduced period of mandibular immobilization followed by appropriate physical therapy could considerably contribute to a more rapid recovery of mandibular kinematics in the postoperative period.
