Evaluation of the relation between occlusal vertical dimension with lingual frenum and depth of muco lingual reflection in Iraqi adult sample

الملخص EN

Back ground : The exact measurement of the natural vertical dimension is most essential in the successful practice of many phases in dentistry, this study was performed to evaluate the use of anterior attachment of lingual frenum and the depth of monolingual reflection when recorded during function as a pre- extraction record to determine the occlusal vertical dimension (OVD) in edentulous patients.

Materials and methods : The sample consisted of 30 dentate subjects, the age was ranged from (23-33) years old, irreversible impressions of lower arches, stock trays, dental stone, surveyor and vernia gauge for measurements, the vertical distance between the incise edge of mandible central incisor and the anterior attachment of lingual frenum as well as the depth of monolingual reflection was measured on the stone casts, t-test and one way analysis of variance were used for statistical analysis of the data.

Results : The difference between males and females regarding the distance from the incise edge of mandible central incisor and the anterior attachment of lingual frenum was statistically not significant (p>0.05) , also gender had no effect on the measurements of the distance from the incise edge of mandible central incisor and muco lingual reflection depth.

Conclusion : The distance between the incise edge of mandible central incisor and the anterior attachment of lingual frenum with the depth of muco lingual reflection may be used as a reliable land marks to determine occlusal vertical dimension.
