Registration of Lower Jaw Movements for Making Complete Dentures

Samson Mghebrishvili

The method of lower jaw movements registration outside mouth, which is accomplished by making use of face arc is not exact and the methods accomplished inside the mouth cavity are too complicated. We have worked out a method of recording lower jaw movements, which is made by means of a saggital masticatory path angle measuring instrument, data of which is indicated in the articulator constructed by us. 120 patients, diagnosis - upper and lower jaws complete adenty have been equipped with dentures. Included, 20 patients have been made two denture sets, each on identical models; one of them was made by means of placing false teeth in individual articulator where recording of lower jaw movements was made using face arc, while the second set of dentures was made by means of our method of recording lower jaw movements. The dentures masticatory efficiency has been studied by means of Rubinov's masticatory test. It has been revealed that dentures made by the method suggested by us are characterized with high masticatory efficiency and are easy to accomplish both, for a dentist and a patient.
