Impression Making for Complete Denture Impression generally is a negative likeness or copy in reverse of the surface of an object. Among the study subjects, 54.9% had retracted tongue position. These forces are most of the time muscular but can also be foreign in nature. The posterior teeth were then repositioned in crossbite relation for repetition of the tests. Vertical forces are involved in retention e.g. Records of thirty five participants were included in the study (mean age of 62.3 years, (range 47-85 years). The data was analysed using SPSS statistical tests like mean, standard deviation, proportion, Chi square test and McNemar Test. Wire loop was attached at the center of denture base on polished surface to attach the hook of nylon fishing line of the retention measuring apparatus to transfer caudal pull till the denture get dislodge from foundation and the values were recorded. 4. Studies have been carried out to modify various steps of complete denture therapy to improve stability in the final prosthesis. Positioning artificial teeth in the neutral zone achieves two objectives. Associations of OHIP-20 scores and several patient variables (age, gender, period of edentulousness, quality of the denture-bearing tissue, denture dimensions, preference) were performed using the generalised linear model.
