Abstract

Background:  The recording of closest speaking space (CSS) during the production of  /s/ sound previously was complicated and expensive, this innovative technique using admixed material in dentulous and edentulous patients is simple and inexpensive. Material and Methods: Admixed interocclusal registration material (7 parts of green stick and 3 parts of impression compound) was placed bilaterally on the occlusal surfaces of mandibular premolar and molar teeth in dentulous and edentulous patients, who were then asked to pronounce the marathi word “Tees” (thirty in English). The recorded CSS was measured in milimeters at minimum thickness on the occlusal records at the first premolar region  with a caliper. The differences in CSS values among dentulous and edentulous patients were statistically analyzed with the unpaired t test. (p<0.001).  Results: The differences in the CSS were significant among dentulous and edentulous patients.The differences in the CSS were only significant in dentulous patients on right and left side but not significant in edentulous patients between left and right side. Conclusion: Within the limitations of this clinical study,it was found that closest speaking space usually incorporated  in the dentures was on an average mare than in  dentulous patients, this decreases  vertical dimension at occlusion but was within physiological range leading to better chewing comfort. This study gives an average values for dentulous and edentulous patients. These values can be used in the clinical determination of the occlusal vertical dimension in removable and fixed prosthetic treatments.
