Sažetak
Hypodontia is the most common developmental anomaly of the human dentition. The aim of this study was to determine the effects of severity and location of hypodontia on craniofacial morphology of Croatian patients by using cephalometric radiographic methods. The sample consisted of 194 patients (119 females and 75 males) diagnosed with permanent dentition hypodontia. Patients were divided into subgroups according to the severity (mild, moderate, severe) and location of hypodontia (anterior, posterior, anteroposterior). A customized cephalometric analysis consisting of 31 angular and linear parameters was performed by DOLPHIN IMAGE software (v.11.5) on lateral cephalograms that were taken as a part of a standard procedure prior to treatment. Our results showed that aneroposterior and severe hypodontia groups have the largest cephalometric differences compared to other subgroups- smaller U1: ANS-PNS angle and especially L1: Me-Go and L1: N-B angles, greater U1:L1 angle and a greater Li-E distance. Combination of a tendency towards Class III malocclusion, due to a clinically significant decrease of SNA and ANB angles and a significantly greater distance between lower lip and E-line leads to a conclusion that subjects with severe and anteroposterior hypodontia are more prone to have a concave profile.
