[The changes of the occlusal relationship from deciduous to the permanent dentition in the longitudinal sample].
The examination of the dynamics of the changes in sagittal, vertical and transversal occlusal relationship has been carried out on the sample of the 66 examinees of the both sexes. The children were examined for the first time at the age of 3.7 years, the again three times repeatedly (within a year) during the first period of the change of teeth. The occlusal changes were registered on the plaster models using the regular standard equipment. The results of the examination of the 4 gnathometric variables (class, overjet, overbite and the transversal occlusal relationship) have demonstrated the following: in 50% examinees the class remained unchanged; the total number of the examinees with class II as well as with uneven occlusal relationship, in the right and left quadrant have increased visibly; the early findings of class II have demonstrated very high stability; the inclination toward the increase of the overjet has been higher in the relation to the reduction; somewhat greater number has been recorded in the group on the overjet above 3 mm; overbite in the major part of the examinees has become deeper; the change from the open, tete a tete, minimal bite to the normal and deep bite has been recorded; the transversal occlusal relationship have remained unchanged in 60% of the cases; the frequency of the new transversal disarrangement in the mixed dentition has been three times higher in the relation to the earlier findings; also the cases of the spontaneous correction of the transversal disarrangement in the deciduous dentition have been recorded.
