In this study the mucolabial reflection was used as aguide to measure the vertical distance of the maxillary and mandibular centralincisors to the vestibules.Materials and Methods: A total sample of 45 subjects was studied that include (25female and 20 male). Impression of the maxillary and mandibular arch was madewith perforated tray using alginate impression material. Stone casts were madeand the distance from the center of the incisal edge for maxillary and mandibularcentral incisors to the depth of the mucolabial reflection was measured. Also thedistance from the depth of the maxillary to mandibular reflection with cast incentric occlusion was measured. The measurements were recorded by the use of adivider and boley gauge to the nearest 0.1 mm.Results: The mean distance from the incisal edge of maxillary central incisors to themucolabial reflection was 21.1 mm for females and 21.8 mm for males while themean distance from the mandibular central incisors to the mucolabial reflectionwas 16.6 mm for females and 16.9 mm for males. Also the mean distance from thedepth of the maxillary to the Mandibular mucolabial reflections was 34.9 mm forfemales and 35.3 mm for males. No statistical significant differences were foundbetween male and female measurements.Conclusion: The mucolabial reflection provides a good starting point for establishinga tentative occlusal vertical dimension. Also could help for a preliminaryarrangement of teeth.
