Abstract


Background : It is generally accepted that an important relationship exists between the arch width and vertical facial morphology. The size and form of the dental arches can have considerable implications on orthodontic diagnosis and treatment planning Aim & Objective : The objectives of this study were to evaluate the relationship between dental arch dimensions and the vertical facial pattern determined by the Jarabak ratio, and to examine the differences in dental arch dimensions between male and female untreated adults Material and method : Lateral cephalograms and study models were obtained from 60 untreated subjects (30 males, 30 females) between 18 and 30 years of age with no crossbite, no/minimal crowding and spacing. The Jarabak ratio (posterior facial height/anterior facial height) was measured on cephalograms of each patient. Study models were used to obtain dental measurements, including maxillary and mandibular intercanine, first interpremolar and first intermolar widths. Results: The results showed that, for both males and females, there was a trend that as vertical facial height increased, arch width decreased and males have significantly larger arch dimensions than those of females. Conclusion: It was concluded that the dental arch width is associated with gender and vertical facial morphology. Thus using individualized arch wires according to each patient’s pre treatment arch form and width is suggested during orthodontic treatment
