Abstract

The purpose of this pilot study was to evaluate the initial effects of the Herbst appliance and determine through the use of common cephalometric radiographs that were optically enhanced and then digitally reproduced, if fossa migration is taking place. Fourteen, (6 male, 8 female), growing patients were treated by the same clinician for the correction of a Class II malocclusion using a modified Herbst appliance. Pretreatment (T1) standard lateral cephalometric radiographs and post Herbst treatment (TH) optically enhanced lateral cephalometric radiographs were taken. All radiographs were digitally captured and reproduced so 6 linear and 1 area measurement could be tested for overall changes in the fossa. The results showed the following: 1) Reliability tests showed good accuracy for both Intra- and inter-examiner reliability with the technique described in this study. 2) The use of the Accurad intensifying screen did not improve the reliability of the points measured. 3) There seems to be little effect on the glenoid fossa, based on the points measured in this study, to support migration of the fossa.
