Estimation of the width of artificial anterior teeth in relation to the width of opposing natural teeth (A comparative study)


The purpose of this study is to determine the width of the missing central incisor of one arch when the central incisor of the other arch is available in personsliving in the north of Iraq, and to compare these measurements with persons living in the middle of Iraq.Four hundred Iraqi students from University of Mosul, North of Iraq were selected for this study, The measurements of maxillary and mandibular central incisors were done on (800) stone casts.A new method was concluded in this study to determine the width of a missing central incisor in relation to the opposing central incisor using the following equation: The width of maxillary central incisor = The Width of mandibular central incisor × 1.65.
