The instantaneous transverse changes in the maxilla due to different points of force application
M. R. Marcotte
The effects of different sites of an expansile force on the maxillae of
three monkeys were studied. A lateral force of five pounds was delivered
directly to four locations on each maxilla. Aluminum rods, rigidly attached
to the teeth of each buccal segment, were photographed before and after
each force application. The data indicated that the pattern of lateral
maxillary displacement is related to the position of the lateral force in
relation to the center of resistance of each maxilla.
