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 One of the major hurdles in clinical prosthodontics has been the selection and replacement of maxillary anterior teeth in the absence of pre-extraction records. The aim of this study was to determine if a relationship exists between intraoral and extraoral facial measurements that could assist dental practitioners in selecting esthetically appropriate maxillary anterior teeth in the ...

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), ...

INTRODUCTION This study assessed the three-dimensional changes in the dental arch of patients submitted to orthodontic-surgical treatment for correction of Class II malocclusions at three different periods. METHODS Landmarks previously identified on upper and lower dental casts were digitized on a three-dimensional digitizer MicroScribe-3DX and stored in Excel worksheets in order to assess th...

Tooth size arch length discrepancy (TSALD) is a well defined means of assessing dental crowding. In previous literature conflicting evidence exists regarding the part played by tooth size and arch dimension in causing dental crowding. The objective of present study were to; examine the relationship between tooth size and arch dimension in crowded and non crowded arches, and to find out the majo...

AIM To compare pretreatment and post-treatment dental arches in relation to intercanine and intermolar width changes in extraction and nonextraction treatment in class I patients. MATERIALS AND METHODS In this retrospective study pretreatment and post-treatment dental casts of 60 patients (30 extractions of first premolars and 30 nonextractions) were selected. Anterior and posterior arch widt...
