RESUMO
Finding the most suitable position for artificial anterior teeth in the absence of pre-extraction records presents a new challenge with every denture and has resulted in a variety of measurements. It encompasses the knowledge of anatomy and physiology of oral tissue. In this study, the relation between anatomical landmarks the tips of the maxillary canines, edge of central incisor and center of incisive papilla was evaluated and compared with respect to arch form in Indian population. Arch forms were accessed by their morphological description as square, tapering or ovoid arch. Measurements on the casts were recorded for incisive papilla and maxillary central incisor distance, by digital vernier caliper and photographic technique was used to record the relation between tips of the canine and the centre of the incisive papilla. The mean distance between edge of central incisor to center of incisive papilla for square arch, oval arch and tapered arch was found as 9.667, 9.991 and 10.912 mm respectively. When all the 300 casts were taken together, it indicated that 51.3 % of intercanine lines passed through the center, 18.1 % of inter canine lines passed posterior and 30.6 % of the intercanine lines passed anterior to the center of incisive papilla. χ(2) (Chi square) values concluded they differ significantly and significant number of intercanine lines crossed through the center of the incisive papilla irrespective of the arch form.
RESUMO
A cleft lip and palate consists of fissures of the upper lip and/or palate, and is the most commonly seen orofacial anomaly that involves the middle third of the face. Early treatment of patients with a cleft lip and palate is important because of esthetic, functional, and psychological concerns. Nasoalveolar molding provides excellent results when started immediately after birth. This clinical report describes the presurgical management of an infant with a complete unilateral cleft of the soft palate, hard palate, alveolar ridge, and lip.
