ABSTRACT
AIM-Evaluative Comparison of the ability of three border molding materials in recording the Functional lateral throat form in completely edentulous mandibular arches. SETTING AND DESIGN-Twenty patients were selected with age ranging from 40-80 years in the study as per the inclusion and exclusion criteria. MATERIALS AND METHOD- 1. The customized instrument used in mandibular arch to measure lateral throat form 2. Border molding materials - Soft liner, addition silicon putty material, low fusing impression compound 3. tray material , medium fusing impression compound The depth of lateral throat form were measure with specially designed instrument and border moulding was done with three different materials in the same patient. Difference in depth of lateral throat form was measured and compared with each other. STATISTICAL ANALYSIS- average value and frequency table RESULTS- 50 % times soft liner gave most exact result CONCLUSION-Within the limitation of the study, it can be concluded that there are difference between the lateral throat form recorded in the patient's mouth and in the functional state.
