OBJECTIVE This study evaluated dental arch dimensional changes of Brazilian children. MATERIAL AND METHODS Dental casts were taken from 66 children (29 males; 37 females) with normal occlusion selected among 1,687 students from public and private schools aged 9, 10, 11 and 12 years, according to the following criteria: Class I canine and molar relationships; well-aligned upper and lower denta...

OBJECTIVE To determine and compare the frequency distribution of various arch shapes in ethnic Malays and Malaysian Aborigines in Peninsular Malaysia and to investigate the morphological differences of arch form between these two ethnic groups. METHODS We examined 120 ethnic Malay study models (60 maxillary, 60 mandibular) and 129 Malaysian Aboriginal study models (66 maxillary, 63 mandibular...

Background: Pont's Index was established to predict maxillary dental arch width from the sum of the mesiodistal diameters of the four maxillary incisors (interincisal width) of the French population. However, the use of Pont's Index in predicting ideal arch shape in orthodontics has been controversial due to racial differences. Pont suggested that the reliability of this Index be tested in othe...

This article describes the treatment of a 61-year-old man who had a completely edentulous maxillary arch and partially edentulous mandibular arch. The patient was orthodontically treated to correct an anterior crossbite by distalization of the mandibular teeth using a removable prosthesis serving as an anchorage unit. Subsequently, the patient received two zygomatic implants, five conventional ...

OBJECTIVE The current study aimed to determine the prevalence and pattern of partial edentulism among dental patients attending the College of Dentistry, Aljouf University, Saudi Arabia. PATIENTS AND METHODS A total of 142 patients were selected, and the prevalence of partial edentulism among the selected patient was recorded. Patients were grouped into three age groups; Group I: 21-30 years,...

BACKGROUND The aim of this study was to determine arch width changes during maxillary first premolars extraction and non-extraction treatment in patients with Class II division 1 malocclusion. MATERIAL AND METHODS Dental casts of 91 Class II division 1 patients (36 males and 55 females) were evaluated. The minimum age of the subjects at the beginning of treatment was above 16 years. 48 patien...

Our purpose was to determine in 20 unilateral cleft lip and alveolus subjects characteristics of the maxillary permanent teeth and maxillary arch development. Clinical and radiographic examinations have been carried out to identify congenitally missing teeth and sagittal skeletal patterns. Study cast assessment was undertaken to evaluate mesiodistal widths of individual teeth, intercanine and i...

The objectives of this study were to estimate the maxillary arch measurements, to assess the validity of Pont's & Korkhaus' Indices; to determine the relationship between maxillary arch form with head form; and to estimate the cephalic index (CI) of the study population. A cross-sectional study was conducted on 85 mature Malay students, 28 male students (32.98%), 57 females (67.02%) attending T...

OBJECTIVE The aim of this study was to analyze tooth movement and arch width changes in maxillary dentition following nonextraction treatment with orthodontic mini-implant (OMI) anchorage in Class II division 1 malocclusions. METHODS Seventeen adult patients diagnosed with Angle's Class II division 1 malocclusion were treated by nonextraction with OMIs as anchorage for distalization of whole ...
