The longitudinal arch between the heel and the forefoot and the transverse arch between the first and fifth metatarsal heads, absorb shock, energy and force. A device to measure plantar pressure was used in 66 normal healthy subjects and in 294 patients with various types of foot disorder. Only 22 (3%) of a total of 720 feet, had a dynamic metatarsal arch during the stance phase of walking, and...

INTRODUCTION The purpose of this study was to evaluate the alveolar bone dimensions and arch perimeter discrepancy in unilateral palatally impacted canines. METHODS This retrospective split-mouth study reviewed 207 cone-beam computed tomography (CBCT) scans of patients with unilateral or bilateral impacted canines referred for orthodontic treatment. Out of 207 CBCT scans, only 39 scans in whi...

OBJECTIVE The purposes of this study were 1) to classify lingual dental arch form types based on the lingual bracket points and 2) to provide a new lingual arch form template based on this classification for clinical application through the analysis of three-dimensional virtual models of normal occlusion sample. METHODS Maxillary and mandibular casts of 115 young adults with normal occlusion ...

OBJECTIVES This study observed midterm results of vascular ring connectors in surgery for aortic dissection. METHODS Vascular ring connectors were used as stents in vascular grafts to achieve quick, sutureless anastomoses. Tapes were used to secure ringed vascular grafts from outside the aorta. RESULTS From November 2007 to February 2011, 113 consecutive patients with aortic dissection, exc...

OBJECTIVE To evaluate early maxillary arch changes in infants with complete bilateral cleft lip and palate (BCLP), using a simple measurement technique. MATERIAL AND METHOD A measurement model technique simplified from previously reported methods was used to analyze early maxillary changes of four non-syndromic complete BCLP. Study models of these cases were evaluated before presurgical ortho...

PURPOSE A variety of impression trays are used in the fabrication of fixed indirect restorations. Impressions used in the construction of fixed indirect restorations were examined for tray type, manner of use, and overall impression quality. MATERIALS AND METHODS A commercial dental laboratory provided 1403 impressions used to fabricate fixed indirect restorations during a 3-month period. Imp...

OBJECTIVE We sought to determine the prevalence of outcomes and associated patient and management factors for neonates with interrupted aortic arch. METHODS From 1987 to 1997, a total of 472 neonates were enrolled prospectively from 33 institutions. Competing risks methodology was used to determine simultaneous risk and associated incremental risk factors for death, initial and subsequent lef...
