Background. It is important to take into account proximity of the incisors’ and canines’ dental alveoli to the incisive canal during immediate implant to prevent injury of the naso-palatine nerve. The purpose of the work is to study topography of the incisive canal and features of its location relative to maxillary incisors and canines in first adult men and women. Materials and methods. 174 first adult persons: 80 men and 94 women, were research objects. Odontometry and study of bone palate parameters were performed on dental cast models. Incisive canal's topography was studied on cone-beam computed tomography. Results. Distance between maxillary central incisors and foramen incisivum decreases when foramen incisivum size increases and this distance becomes longer when absolute size of maxillary teeth increases. When bone palate height increases in frontal and sagittal planes, distance between foramen incisivum and maxillary lateral incisors and canines decreases. The distance between the apical parts of maxillary central incisors' alveoli and incisive canal increases when number of nasal foramens decreases. The distance from incisive canal to the apical parts of maxillary central and lateral incisors' alveoli increases when canal inclination relative to bone palate plane increases. Conclusion. The incisive canal has a pronounced individual variability of topography and location features relative to the maxillary incisors and canines.
