Abstract


Templates are very useful tools for diagnosis of malocclusions. A number of templates have been provided for some populations in previous years. Since craniofacial characteristics of different ethnic groups are not the same, each population needs its own norms. The aim of this study was to provide orthodontic craniofacial templates for 8-16 year old Iranian boys and compare dentoskeletal features between Iranian and western populations. 3330 boys with the age range of 8-16 years were examined in Tehran, and 107 cases were finally chosen for the study and their lateral cephalograms were traced. Since there is no universal, consensus about the selection of one specific point or line for cephalometric superimposition, both the sella nasion (SN) and basion nasion (Ba-N) lines were chosen for this purpose. Based on both SN and Ba-N lines, a template was prepared for each age. Simple linear regression analysis was used to evaluate the angles and the multivariant regression analysis for evaluation of landmark vectors. Posterior cranial base, maxillary and mandibular lengths, upper and lower anterior facial heights (N-ANS and ANS-Me) and posterior facial height (S-Go) are greater in Iranian population. But anterior cranial base, height and inclination of the incisors and molar height are similar in two populations.
