[Analysis of interdental contacts during experimental mastication]

The author established that during mastication of experimental silicon morsel the teeth get get in contact in 3/4 of the 32 subjects examined, with 6.25 close contacts on the average for each half jaw. The observations on the separate stages of masticatory cycle reveal that the morsel is turned round between dentition, cheek and tongue, and about 90 degrees the closing of dentition follows to contact, continued to the final fragmentation of the morsel.
