Crowding is one of the causes of class I malocclusion. The purpose of the present study was to examine the relationship between arch length, arch width and arch perimeter in crowded and non-crowded arches, as well as to made comparison of the right and left sides between them and to find out the contributing factor in lower arch crowding. The study groups consisted of 60 subjects aged 16 to 21 ...

OBJECTIVE Implants are being used in orthodontics as a reliable mode of anchorage. Among other factors, the cortical bone thickness plays a major role in determining the stability of these implants. The objective of this study was to study the relationship of various arch forms and the cortical bone thickness and to determine if the cortical bone thickness varies between various arch forms. Thi...

OBJECTIVE To compare dental arch dimensions and arch forms in various vertical facial patterns. STUDY DESIGN Cross-sectional comparative study. PLACE AND DURATION OF STUDY The Aga Khan University Hospital, Karachi, from June 2007 to May 2008. METHODOLOGY Cases of age ranging 13-30 years were reviewed having full complement of teeth (upto second permanent molars) with less than 7 mm crowdi...

BACKGROUND Dental crowding is the one of the most frequently encountered problem for an orthodontist. The relationship between crowding and various skeletal, dental and soft tissue parameters is important to establish and consider during the overall orthodontic treatment planning. This study aimed to determine the correlation of maxillary and mandibular base lengths with dental arch crowding in...

INTRODUCTION Although there are numerous studies in the literature on alignment stability in the lower arch, there are few referring to the upper arch. AIMS To assess upper arch stability (irregularity index, widths and length of arch, overjet and overbite) in orthodontically treated patients by comparing late incisor stability with the initial malocclusion and type pf treatment undertaken. ...

Background: In many human postural studies, the foot is considered to be a rigid body. The human foot is composed of the arch structure, which is characteristic in every person and deforms with aging. Foot arch structure is assumed to effect postural control; however, underlying mechanisms remain unclear. The aim of this study was to elucidate the relationship between the structure of the foot ...

The aim of this investigation was to assess the dentofacial changes in a group of patients consecutively treated with Tip-Edge appliances and the extraction of four permanent second molars by one specialist orthodontic practitioner. Before and after treatment lateral cephalograms and study cast measurements of 45 individuals, 26 females (mean age 13.8 years) and 19 males (mean age 13.9 years), ...
