OBJECTIVE Evaluation of the effect of infant orthopedics on maxillary arch dimensions in the deciduous dentition in patients with unilateral cleft lip and palate. DESIGN Prospective two-arm randomized controlled clinical trial with three participating cleft palate centers. SETTING Cleft palate centers of the Radboud University Nijmegen Medical Center, Academic Center of Dentistry Amsterdam,...

  In this study two groups of dental study models were selected to evaluate the relationship between the tooth size, arch dimensions , and dental crowding. The first group consisting of 56 pairs of dental study models (28 males and 28 females) with normal occlusion ( without dental crowding) ranging in  age from 16 to 20 years, were selected among 4445 students from Kerman by multi stage rando...

The associations between the aortic dimensions (of the aortic sinus, aortic annulus and aortic arch) and physiological variables have not been established in the Chinese population. The present study examined the associations among physiological variables to determine the aortic root and arch dimensions echocardiographically. The diameters of the aortic sinus, annulus and arch were measured in ...

Introduction Axillary arch is an additional muscle bundle of various dimensions extending from latissimus dorsi in the posterior fold of the axilla, to the pectoralis major in the anterior fold, to the short head of the biceps brachii or to the coracoid process [1, 2]. Ramsay, in 1795, described the axillary arch for the first time. He gave the description of a muscle bundle connecting pectoral...

This study investigated the early effects on mandibular incisor irregularity and rotation together with dental arch dimensions of the extraction of four deciduous canines. Children, during early mixed dentition, were randomized into one extraction (n = 32) and one control (n = 41) group. Dental casts from baseline (T0) and 1 year follow-up (T1) were used to evaluate changes in the irregularity ...

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...

AIM Thalassemia is a group of inherited hemoglobinopathies with thalassemia major representing the severe form of the disease characterized by craniofacial deformities. The aim of this study is to provide a detailed description of dental arch dimensions in subjects with thalassemia major. SUBJECTS AND METHODS The sample consisted of 43 thalassemic subjects, 24 males and 19 females, aged 7.3 t...

Q2. Damon arch form has broader posterior width than Ortho Form II. Compared to the self-ligating system group (Damon arch form used), conventional system group (Ortho Form II used), showed narrower posterior width as the shape of their arch form, and also had longer arch length and depth. Because the arch dimensions of the two groups were similar before treatment, it can be interpreted that th...
