The gingival zenith is the most apical point of the gingival outline. This study aimed to quantify the mesio-distal and apico-coronal displacements of gingival zenith in maxillary anterior dentition. 50 healthy patients, who ranged in age from 25 to 36 years were recruited for the study. Alginate impressions of the study group were made and poured with the type III stone. The gingival zenith positions of maxillary anterior teeth were measured in a mesial-lateral direction from the vertical bisected midline. The apico-coronal displacements of the gingival zenith of lateral incisors were measured from a line joining the gingival zeniths of the central incisor and canine. The gingival zeniths were distally displaced in 90%, 53% and 23% of the maxillary cetral incisors, lateral incisors and canines respectively. The mean distal displacements of the gingival zeniths to the vertical bisected midline of central incisors, lateral incisors and canines were 0.90 mm, 0.29 mm and 0.06 mm respectively. The gingival zeniths of lateral incisors were positioned mm coronally to the line joining the gingival zenith of central incisors and canines. Consideration of these findings may improve restorative procedures in the anterior maxillary dentition.
