[Changes in kinetic system of the mastication organ in patients with pterygoid dental losses in the mandible].
100 patients with pterygoid dental losses in the mandible randomly selected from the group of 900 patients have been examined. The material under examination has been divided into two groups (according to Kennedy's classification). I group--the persons with both-sided pterygoid dental losses, II group--the persons with one-sided pterygoid dental losses. Presence both extraoral and intraoral changes of the mastication organ in both groups as well as SSZ dysfunction symptoms has been analysed. The results obtained have proved that pterygoid losses essentially influence the presence of extraoral changes and less so the presence of intraoral changes. The span and type of dental losses have influenced the frequency of the presence of such changes as: cheeks' retraction, intensifying of nasolabial sulci, lowering of vertical dimension of the bottom face segment, attrition of teeth, presence of diastems in the maxilla and mandible, enlargement of the resting mouth silt etc. SSZ dysfunction symptoms have been found in 64% of the persons under examinations; intensification of these symptoms was positively greater in the patients with asymmetric losses, i.e. with one-sided losses. The examinations carried out demonstrate the need of all pterygoid dental losses restoration, particularly one-sided losses in the prophylaxis of mas-dysfunction generation.
