Orthodontic treatment for malocclusion correction may involve extraction or non-extraction of specified teeth for esthetic and functional harmony. Antero-posterior and transverse arch dimensional changes following orthodontic treatment has been evaluated using many methods. The present study evaluated the arch dimensional changes after orthodontic treatment in extraction and non-extraction case...

The objective was to analyze variations in dental arch width in relation to oral habits. Maxillary and mandibular intercanine and intermolar distance were determined in relation to certain oral habits in 1297 children (ages 3 to 6 years). After an oral examination, the parents of each child completed a questionnaire about oral habits, including the use of a dummy or a bottle (or both), finger s...

PURPOSE The aim of this study was to investigate dental arch dimensions and to classify arch shape in Korean young adults. MATERIALS AND METHODS The sample included 50 Koreans with age ranging from 24 to 32 years. Maxillary and mandibular casts were fabricated using irreversible hydrocolloid and type III dental stones. Incisor-canine distance, incisor-1st molar distance, incisor-2nd molar dis...

Tooth morphometry is known to be influenced by cultural, environmental and racial factors. Tooth size standards can be used in age and sex determination. One hundred models (50 males & 50 females) of normal occlusion were evaluated and significant correlations (p<0.001) were found to exist between the combined maxillary incisor widths and the maxillary intermolar and interpremolar arch widths. ...

BACKGROUND No randomized controlled trial has tried to compare transverse dental arch changes between the lingual and labial orthodontic fixed appliances in the early stage of treatment. OBJECTIVE To compare upper dental arch changes between lingual and labial fixed orthodontic appliances after leveling and alignment. DESIGN, SETTING Parallel-groups randomized controlled trial on patients w...

Cleft malformations belong to the most common facial congenital defects. This study compares the impact of early and late reconstruction of complete unilateral cleft lip and palate on the growth and development of the posterior part of dentoalveolar arch. Maxillary dental casts of 35 infants were used for analyses. They were divided into 2 groups according to the timing of the lip reconstructio...

Postnatal growth of the face is a composite function of genetic and environmental factors. A sudden traumatic insult due to the use of forceps at birth could have long-term effects which could detrimentally influence growth and development. This study examines the development of the skeletal and dental components of forceps vs. non-forceps-delivered patients. The association between delivery me...

The role of intercuspation of the teeth in transverse maxillary growth and dental arch development was investigated radiographically with the aid of implants in Macaca fascicularis monkeys. Fourteen animals were randomly allocated to a control group (n = 7) and an experimental group (n = 7) and were followed from 29 to 100 weeks of age. Intercuspation was eliminated in the experimental group by...
