Abstract
Occlusal wafers are commonly used to establish the position of occlusion during orthognathic operations. Various problems have been encountered in the construction of these wafers. To overcome problems related to labor intensity, dimensional stability, and occlusal accuracy, a new technique for making wafers has been developed using light-cured acrylic resin. To stabilize the wafer during operation, an orthodontic elastic power chain is incorporated into the wafer. Advantages of this new technique include a shorter intermaxillary fixation time after orthognathic operations and a shorter construction time in the laboratory as compared with conventional techniques.
