The aim of this research was to determine the choices made by clinicians with respect to archwires and arch form during the initial and latter stages of orthodontic treatment with fixed appliances. A questionnaire-based study was carried out at Bristol Dental Hospital between November 2005 and March 2006. Questionnaires were distributed within the dental hospital and at local meetings in order ...

Introduction: Etiology of dental crowding may be related to arch constriction in diverse dimensions, and an appropriate manipulation of arch perimeter by intervening in basal bone discrepancies cases, may be a key for crowding relief, especially when incisors movement is limited due to underlying pathology, periodontal issues or restrictions related to soft tissue profile. Objectives: This c...

Dento-alveolar disharmony with crowding is a common reason for orthodontic treatment not fully understood or unequivocally demonstrated causes. This study investigated the correlations between teeth dimensions, arch lengths, and during mixed dentition period. A cross-sectional on 100 dental casts of patients class I malocclusions was performed. Dental arches were classified as non-crowded, mode...

Human embryos aged six and one-half through 12 weeks were studied to determine the morphological changes in shape of the maxillary dental arch during this early developmental period. Age was determined by crown-rump lengths using the table of Patten ('53). When compared to a reference catenary curve, the embryonic dental arch exhibited several time-linked and directional changes in shape. First...

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. th...

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 ...

AIM. This paper is an attempt to compare and analyze the various mathematical models for defining the dental arch curvature of children in normal occlusion based upon a review of available literature. Background. While various studies have touched upon ways to cure or prevent dental diseases and upon surgical ways for teeth reconstitution to correct teeth anomalies during childhood, a substanti...

Objective. This study aimed to investigate the impact of subject age, gender, and arch length on dentists' attitudes towards unrestored shortened dental arches. Materials and Methods. 93 Syrian dentists were interviewed and presented with 24 scenarios for male and female subjects of different ages and shortened dental arches of varying length. Participants were asked to indicate on a standardiz...
