Long-term evaluation after chincap treatment.
The purpose of this study was to investigate the skeletal changes occurring during and after chincap therapy. The subjects of this study, with a mean age of 9 years 3 months, consisted of 27 patients; all of whom possessed an anterior crossbite. Of these patients, 15 had skeletal Class III and the remaining 12 had skeletal Class I malocclusions with anterior crossbites. The applied total force with the chincap was 600 grams and the mean treatment period was 12 months. The changes during and after treatment were analysed by using linear and angular cephalometric measurements. The result obtained in this investigation was that in skeletal Class I and Class III cases, successfully treated by a chincap appliance, where the necessary overjet and overbite relationship was obtained, the abnormality tended to return to the original position during the period following chincap removal.
