Aims: Tissue stress evaluation at border seal area using patient-manipulated custom tray-modified closed-mouth functional technique for flat mandibular ridges. Materials and Methods: Thirty completely edentulous participants of either sex, between 50 and 70 years of age, requiring Atwood order number five residual ridge were selected. The materials were used to record tissue stress area includes tissue conditioner (G.C. Reline), pattern resin (LS 1:1 PKG GC America INC for patterning), putty addition silicon (Dentsply Aquasil Soft Putty/Regular Set), and low-fusing compound (DPI Pinnacle-tracing sticks). Custom tray was modified at tray handle area by forming new functional handle to enhance patient motivation to perform functional movements. In total, six areas of tissue stress were evaluated under image analyzer stereomicroscope. Results: All values were subjected to ANOVA statistics. However, descriptive analysis of means of test group (pattern resin: 1.897 mm, low fusing compound: 2.817 mm, and putty addition silicon: 2.410 mm) were significantly different compared to that of control group (tissue conditioner 1.512) (P = 0.000). Mean of tissue stress value recorded by pattern resin was nearer to mean of control group. Conclusion: Custom modified tray technique along with pattern resin records the tissue detail more precisely with minimum tissue stress and greater motivation of the patient to perform functional movements.
