| Abstract | ||
| Background: Different methods are being used in prosthodontics for determining occlusal vertical dimension. In this study the mucolabial reflection was used as a guide to measure the vertical distance of the maxillary and mandibular central incisors to the vestibules. Materials and Methods: A total sample of 45 subjects was studied that include (25 female and 20 male). Impression of the maxillary and mandibular arch was made with perforated tray using alginate impression material. Stone casts were made and the distance from the center of the incisal edge for maxillary and mandibular central incisors to the depth of the mucolabial reflection was measured. Also the distance from the depth of the maxillary to mandibular reflection with cast in centric occlusion was measured. The measurements were recorded by the use of a divider and boley gauge to the nearest 0.1 mm. Results: The mean distance from the incisal edge of maxillary central incisors to the mucolabial reflection was 21.1 mm for females and 21.8 mm for males while the mean distance from the mandibular central incisors to the mucolabial reflection was 16.6 mm for females and 16.9 mm for males. Also the mean distance from the depth of the maxillary to the Mandibular mucolabial reflections was 34.9 mm for females and 35.3 mm for males. No statistical significant differences were found between male and female measurements. Conclusion: The mucolabial reflection provides a good starting point for establishing a tentative occlusal vertical dimension. Also could help for a preliminary arrangement of teeth. | ||
