Read the detailed description
This study is aimed to assess the prevalence of different incisal angle of maxillary central incisors in a sample of adults population with sound anterior central incisors. The current study will include 500 sound natural maxillary central incisors in 350 Participants. For each, an intraoral scan will be taken to measure the incisal angle. , wither having a mesial or distal incisal angle and its degree and how frequent each one. the scans will be aligned in same xyz axis for proper standardization for the measurements.
