[Comparative studies of the grinding methods by Jankelson and Lauritzen]

First functional analyses according to Lauritzen were performed in 10 patients and the models were ground in the Dentatus articulator. Then the natural dentition was ground in according to Jankelson in retruded contact position. The results of intraoral grinding-in after an average of 3--4 sessions were transferred to the Dentatus articulator by means of the split cast method and analysed. Comparison showed that the result of intraoral grinding-in according to Jankelson was clearly inferior to that achieved in the articulator.
