The objectives of this study were to investigate if a relationship exists between dental arch width and the vertical facial pattern determined by the steepness of the mandibular plane, and to examine the differences in dental arch widths between male and female untreated adults. Lateral cephalograms and dental casts were obtained from 185 untreated Caucasians (92 males, 93 females) between 18 a...

Intercanine width, intermolar width and arch length are essential for diagnosis and treatment planning and are closely related factors in orthodontics.The purpose of this study was to determine the correlation between these measurements and how these measurements are related to each other. Dental casts of 100 orthodontic patients (72 females and 28 males) with a mean age of 18.7 years (12-38 ye...

Introduction With the advancement in imaging technology, 3D dental computed tomography plays a very significant role in orthodontic treatment and diagnosis. Aim To evaluate dental crowding in relation to the mesiodistal crown widths and arch dimensions and also to determine the differences of dental crowding among males and females, in Southern Indian population. Materials and Methods A tot...

The treatment of Class I malocclusion treatment is to arrange the teeth position in a good arch form. Arch form consists of tooth size and arch dimension (intercanine width, canine depth, intermolar width, molar depth). Several ways are developed to describe arch form. A lot of methods used to describe arch form qualitatively. The objective of this study is to develop qualitative arch form diag...

BACKGROUND Differences in the dental arch among Bhil Aboriginals were investigated and compared with non-tribal individuals residing in a tribal zone of Central India. Plaster models (120) were made with the help of alginate impression of tribal adults as well as non-tribal adults residing in the same area. The supposition as aboriginals being primitive due to dietary practices maxillary arch s...

The purpose of this study was to establish tooth width and arch dimensions in normal and malocclusion samples and to compare tooth width and arch dimensions between males and females in normal and malocclusion samples. A total of 120 pairs of orthodontic study casts were included in the study. An electronic digital caliper was used for the measurements. Descriptive statistics and the t-test wer...

OBJECTIVE To evaluate early maxillary arch changes in infants with complete bilateral cleft lip and palate (BCLP), using a simple measurement technique. MATERIAL AND METHOD A measurement model technique simplified from previously reported methods was used to analyze early maxillary changes of four non-syndromic complete BCLP. Study models of these cases were evaluated before presurgical ortho...

BACKGROUND AND AIM: Tooth extraction as a part of orthodontic treatment plan to create space for leveling and aligning teeth or causing tooth movement leads to changes in arch width and length. The outcome of these changes is important for the clinicians and affects the treatment and retention plans. Despite some previous studies, data in this regard are still scarce and further investigation i...

Lip bumper treatment has been shown to successfully increase arch width, procline the incisors, and distalize molars. However, few studies have been performed showing the long-term stability of lip bumper treatment. In this study, mandibular casts taken by a single practitioner from 51 patients treated with lip bumpers without rapid palatal expansion were analyzed at pretreatment, post-lip bump...
