Abstract
Abstract Objective This study aims to determine the freeway space (FWS) using lateral profile photograph (LPP) as an adjunct in completely edentulous patients. Materials and Methods In this study, 30 patients in the age group of 45 to 60 years who met with the criteria were included. LPPs were taken for all participants using standard protocol and a duplicate copy was obtained, on which three soft tissue reference points—porion (Stp), gnathion (Stgn), and gonion (Stg)—were marked and joined to form an angle Stp-Stg-Stgn. This angle was correlated with the mean FWS obtained using swallowing. Simple linear regression model was used to develop a prediction formula for FWS using Stp-Stg-Stgn angle as the independent variable. Result This study shows that the angle Stp-Stg-Stgn had a significant negative correlation with FWS.
