1. Тheme of lecture: Occlusive surface correction as the preparatory stage for dentition restoration with prosthetic devices. 1

2. Plan of lecture: 1. Etiology of teeth and jaw deformations. 2. Pathogenesis of teeth and jaw deformatis. 3. Classification of deformations: A) vertical B) horizontal 4. Clinics of dental rows deformitions 5. Methods of treatment of dental rows deformations: -methods of selective preparation -methods of disoclusion -aparature-surgical treatment -orthodontic treatment -surgical treatment 2

3. Correlation of teeth in case of violation of occlusion surfaces 3

4. Clinical deformations of dental curves in case of antagonists absence. ц 4

5. Violation of occlusal surfaces of dentition is an obstacle to free movement of lower jaw 5

6. Clinics of deformation of teeth rows: -partial dental defect -occlusal curve disorders -disorders of lower jaw movements -restructuring of reflection of chewing muscles -changes in the nervous regulation, circulation, neurotrophic -reduction of the distance between the occlusal surface of the mucous membrane and alveolar bone -increasing of the volume of alveolar processus -the local resorption of the bone at subcompensated and decompensated form 6

7. Deformation of teeth rows, similar to the phenomenon of Popov-Godon 7

8. Schematic representation of Godon’s articulation equilibrium 8

9.  The plate(a) and the frame of clasp denture(b) for the treatment of deformations of teeth rows 9

10. The variety of fixation of bridge denture in case of the medial location of the molars 10
