Temporal and distance parameters of 33 normal children were obtained from instrumented gait analysis prospectively over five consecutive years. The parameters were normalised to minimise the confounding effects of increasing height and leg length. Rank correlations were performed on normalised speed, normalised stride length, normalised cadence and(More)
Seventeen cases of cleidocranial dysplasia were analysed. On average, there was mandibular prognathism due to increased mandibular length, and a short cranial base. The maxilla was short vertically but not antero-posteriorly. In 13 young subjects followed for an average period of 6 years, more than half of the total number of teeth of each type had not(More)
The purpose of this study was to determine the effect of simulated hamstring shortening on gait in normal subjects. Six normal subjects wore an adjustable brace to simulate three different hamstring lengths. Evaluation of the physiological cost index (PCI) and gait analysis revealed that simulated hamstring shortening produced adverse affects in the gait of(More)
The sample consisted of 28 patients (16 female: 12 male) from the records of the Orthodontic Department for whom the extraction of both lower first permanent molars was considered due to caries. The age ranged from 8-14 years (mean age 12.4). A cephalometric radiograph was taken prior to the extraction and after a mean of 18 months. No other treatment was(More)
Twenty-three patients (10 male, 13 female), with Class III relationships of the incisor teeth at the mixed dentition stage, were treated with the chincap appliance associated, where appropriate, with an upper removable appliance to procline upper incisors and to free the occlusion. Cephalometric analyses at the beginning and at the end of active treatment(More)
Changes in incisor overbite were compared in 33 subjects who had four second molars extracted and 33 untreated subjects. There was an average increase in overbite of 0.7 mm in the extraction group, significantly different from an average decrease of -0.8 mm in the control group. The tendency to increase in overbite was greater in subjects whose presenting(More)
Reduction of the maxillary tuberosities is not always possible when indicated, and it is sometimes necessary to solve the problem by modifying the construction procedures for the complete denture. Because of inadequate space between the maxillary tuberosity and the retromolar pad, acrylic bases of adequate thickness could not be used. Instead, gold shims(More)
True lateral cephalometric radiographs of 20 adult male British subjects and 20 Nigerian adult males were collected. All subjects showed an ideal occlusion of the teeth. These radiographs were analysed using a facial polygon joining the points Nasion, Sella, Articulare, Gonion and Menton. Additionally, measurements were made of the axial inclination of the(More)
