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...

The aim of the present study was to measure the dental arches in order to assess the potential influence of third molars on lower incisor crowding. Changes in dental arch dimensions were assessed in 47 patients (36 females, 11 males) three years following either removal of the third molars or deciding to leave them in situ. A dental pantomogram (DPT) was taken at the start of the study and plas...

Great smiles have harmony, symmetry, and a broadness consistent with the individual’s facial form, morphology, and balance. Smiles communicate, are expressive, and especially beautiful when full. People do not perceive narrow arch smiles to be appealing. A proportional smile fills the lip embrasures and eliminates black triangles. We see this as beauty in nature, and such symmetry is preferred ...

Objectives: In recent years, substantial effort has been evident in the field of mathematical analysis of the dental arch curve, particularly of children from varied age groups and diverse ethnic and national origins. Many eminent authors have put forth mathematical models to describe the teeth arch curve in humans. Each such model had advantages and disadvantages, but none could exactly define...

Panoramic X-ray (PX) provides a 2D picture of the patient's mouth in panoramic view to help dentists observe invisible disease inside gum. However, it limited information compared with cone-beam computed tomography (CBCT), another dental imaging method that generates 3D oral cavity but more radiation dose and higher price. Consequently, is great interest reconstruct structure from image, which ...

OBJECTIVE There are various risk factors which play an essential role in the multifactorial disease "dental caries." Although absence of interdental spaces in the primary dentition may increase the risk of dental caries, not many studies have been carried out to assess this correlation. This study was performed to assess the relationship between interdental spacing and dental caries in primary ...

objectives: this study sought to evaluate the accuracy and errors of linear measurements of mesiodistal dimensions of kennedy class iii edentulous space using cone beam computed tomography (cbct) in comparison with clinical measurements. materials and methods: nineteen kennedy class iii dental arches were evaluated. an impression was made of each dental arch and poured with dental stone. the di...

This study was conducted to determine the morphology of mandibular dental arch forms. Two different methods were used for this purpose and compared to find out the frequency distribution. It was conducted on 100 patients visiting Lahore Medical and Dental College, Lahore. Dental casts were photocopied and investigated to find out the square, tapering and ovoid arch forms. A mathematical model o...

The aims of this paper were to review the literature on shortened dental arches with special focus on publications of the Käyser/Nijmegen group, and to evaluate the discussions on the shortened dental arch concept found in the literature. A MEDLINE (PubMed) search was conducted for articles in English published in the dental literature from 1966 to November 2005. The search revealed epidemiolog...

The effect of the use of a lip bumper with anterior vestibular shields on the maxilla was studied in twenty-two 9-14-year-old children with a space deficiency in the maxillary dental arch. The lip bumper was used for 1 year. The effect of the treatment was evaluated from dental casts and profile cephalograms made before and after treatment. Both the width of the maxillary dental arch at the pre...
