Dental arch width dimensions have been measured by use of certain cusp tips (MOORREES, The Dentition of the Growing Child, 1959) or points at the lingual cervical margin of the teeth (BAUME, J Dent Res 29:123, 1950) as reference points. However, cusp tips wear off, vary in number and location, and do not allow adequate transformation from the deciduous canines and molars to their successors (Fi...

BACKGROUND Anchorage onto permanent dentition is a common procedure in rapid maxillary expansion. However, replacing first permanent molars with the second deciduous molars seems to be an option to reduce some negative side effects during orthodontic treatment. The purpose of this study was to evaluate the dental effect of rapid maxillary expansion with anchorage exclusively onto deciduous teet...

OBJECTIVE To investigate the maxillary and mandibular anterior crown width/height ratio and its relation to various arch perimeters, arch length, and arch width (intercanine, interpremolar, and intermolar) groups. MATERIALS AND METHODS The calculated sample size was 128 subjects. The crown width/height, arch length, arch perimeter, and arch width of the maxilla and mandible were obtained via ...

OBJECTIVE The aim of this study was to clarify the morphological differences in the mandibular arches of Turkish and North American white subjects. METHODS The sample included 132 Turkish (34 Class I, 58 Class II, and 40 Class III) and 160 North American (60 Class I, 50 Class II, and 50 Class III) subjects. The most facial portion of 13 proximal contact areas was digitized from photocopied im...

UNLABELLED The aim of this study was to analyze and to compare the dental and skeletal morphology of mono- and dizygotic twins (MZ and BZ). MATERIAL AND METHODS 10 sets of monozygotic (mean age: 18.5 years) and 10 sets of dizygotic (mean age: 19.7 years) twins were examined, cast analysis, ortopantomography and lateral cephalometric films were analyzed. RESULTS The upper frontal teeth dimen...
