A total of 969 proximal contacts in forty volunteer subjects was examined for proximal contact integrity with shim stock. It passed uninhibited through 88% of the contacts. Neither sex nor age affected the evaluation; however, shim stock was more likely to pass through contacts with enamel surfaces than those which were restored.
Previous studies have shown that the human resting dentition naturally exhibits slight interproximal spacing between 80% to 90% of all adjacent teeth. The purpose of this study was to measure occurrence and dimension of interproximal spacing. Pieces of shim stock of various thicknesses were used to measure the dimension of interproximal spaces between… (More)
INTRODUCTION Palatal expanders have been advocated for spontaneous correction of some Class II malocclusions. However, little research has been done to determine whether correction or improvement actually occurs with expansion. Past research has not shown whether an anterior functional shift is achieved in patients who have Class II improvement. The… (More)
Disocclusion of the teeth has been postulated to have a deregulating or promoting influence on mandibular growth. The clinical effects of disocclusion were evaluated with a prospective pilot study of 16 children with mixed dentition who wore either a maxillary Hawley biteplane or the functional regulator of Fränkel. The pilot study was used to assess… (More)
In locating condylion (Co), clinicians have used cephalograms in maximum mandibular opening to provide a clearer image of the condyle. The purpose of this study was to evaluate the accuracy of identifying condylin on a sample of open and closed mouth cephalograms of 20 patients. Five orthodontists traced each mandibular outline and located condylion and the… (More)
