A frameshift mutation recently identified within the paired domain of the transcription factor, PAX9, has been linked to a unique form of oligodontia in a single, multigenerational family (Stockton et al., 2000). We now describe the phenotypic and segregation analyses of this remarkable kindred, the initial approach taken to identify a candidate gene(More)
OBJECTIVE This study was designed to evaluate the effectiveness of helmet therapy (DOC band) in the correction of patients with moderate to severe posterior deformational plagiocephaly. DESIGN In this prospective study, the infants were evaluated using 18 anthropometric measurements. PATIENTS The charts of 248 patients seen between August 1, 1995, and(More)
Cephalometric studies of adult Mexican-Americans are incomplete. The purpose of this study was to evaluate whether significant cephalometric differences exist between adult Mexican-American, black American, and white patients. Lateral cephalometric radiographs were taken of 48 Mexican-American adults (23 men, 25 women). All subjects met the following(More)
PURPOSE The purpose of this study was to determine the in vitro accuracy of a new protocol for distraction osteogenesis of the mandible that involves a planning process and a surgical technique. MATERIALS AND METHODS An experimental design was developed to simulate distraction osteogenesis on stereolithographic models of patients with craniofacial(More)
To be reaffirmed in 1987 for lack of a ready replacement, the flexural (elastic-bending) test protocol of ADA Specification No. 32 is judged inadequate. The protocol is problematic because of potentials for erroneous use of the theoretical component, incompatible with the flexible titanium alloy and multistrand stainless steel wires marketed subsequent to(More)

INTRODUCTION One method of articulating digital models is to use a digitized interocclusal record. However, the accuracy of different interocclusal record materials to articulate digital models has yet to be evaluated. METHODS A plastic typodont was modified with reference points for interarch measurements and articulated in maximum intercuspal position(More)
