[Transformation of the temporomandibular joint in the treatment of sagittal bite anomalies].

The results from distocclusion and mesiocclusion treatments were radiologically evaluated in 89 patients. In two experiments, mesiocclusion and distocclusion were produced in monkeys by means of cemented inclined planes. The transformations thus achieved were evaluated by radiography, histology and craniometry. The treatment of distocclusion results in an increase in size of the mandible, of the angle of the mandible, and of the lower third of the face. The head of the condyle erects itself. Reactive tissue changes (activation of the osteoblasts and osteoclasts, accelerated ossification of the cartilage) were seen in the dorsal part of the head of the condyle. Thus, the theory of Breitner is not confirmed. There were no resorption phenomena at the articular eminence and in the anterior part of the head of the condyle, and no so-called pressure and traction zones.

[The optimal times for the surgical treatment of children with congenital cleft lip and palate].

Analysis of the remote results of surgical, orthopedic, and orthodontic treatment of children with cheiloschisis has demonstrated that early surgery of the palate results in development of grave maxillodental deformations involving prolonged many-stage orthodontic treatment, not always effective. The authors claim that surgery on the palate is advisable at the age of 5-7 in children with subtotal palatal clefts and at the age of 10-11 in those with total unilateral and bilateral clefts. Before surgery the child is to be provided for with an occlusive palatal plate starting from the first month of his life and should be administered orthodontic treatment, if necessary.
