PURPOSE The aim of this study was to investigate dental arch dimensions and to classify arch shape in Korean young adults. MATERIALS AND METHODS The sample included 50 Koreans with age ranging from 24 to 32 years. Maxillary and mandibular casts were fabricated using irreversible hydrocolloid and type III dental stones. Incisor-canine distance, incisor-1st molar distance, incisor-2nd molar dis...

OBJECTIVE To determine and compare the frequency distribution of various arch shapes in ethnic Malays and Malaysian Aborigines in Peninsular Malaysia and to investigate the morphological differences of arch form between these two ethnic groups. METHODS We examined 120 ethnic Malay study models (60 maxillary, 60 mandibular) and 129 Malaysian Aboriginal study models (66 maxillary, 63 mandibular...

Since 1991 ten patients, 9 male and 1 female, with aortic arch aneurysm underwent surgical therapy with trapdoor thoracotomy. The mean age was 67.4 +/- 9.1 (standard deviation) years at operation. In addition to the aortic arch repair, we also performed seven descending aortic replacements. We performed one partial arch replacement, one total arch replacement, and one aneurysmorrhaphy and wrapp...

Background The foot arch serves important functions in regard to shock absorption and the action of walking. Simple and quantitative classification of foot arch types such as flat foot and high arch would be helpful in health support for the elderly. The present authors have developed a classification system for foot arch type showing high reliability using foot pressure distribution data [1,2]...

introduction: a study model is a precise three dimensional replica of patient’s dentition and plays an important role in treatment planning. many digital multi-media applications have become available to the clinician and his or her staff to facilitate standard procedures in practice and management. the aim of this study is to evaluate reliability and validity of dental measurement made on digi...

the aim of this paper is to explore conventional methods of teaching the arch-design studio withideas of sustainability and creativity as agents of change. if this is realised, it means the students of architecture canbe grounded in designing with sustainability and creativity ideas and can be professionals that design and build withideas of creativity and sustainability. so, there are real bui...

Arch extension of aortic dissection (AD) is reported to occur in 4-25% of patients presenting with acute type B AD. The DeBakey and Stanford classifications do not specifically account for this subset, however, recent studies have demonstrated that the prognosis of patients with arch extension in acute type B AD is virtually identical to that of others with type B AD. In this sense, it seems re...
