case_images: Tissue conditioning material was applied on the tissue surface of mandibular denture base and patient was asked to close the mouth in the prerecorded vertical dimension and do various functional movements such as puffing, blowing, whistling, and smiling (Figure 5).

case_images: This helps to stabilise the tray in position by preventing anteroposterior and mediolateral displacement of the tray during definitive impression (Figure 6).
case_images: Elastomeric technique.

case_images: A wire loop (0.9 mm in diameter) was placed on the geometrical center of the polished lingual surface to which the pull end of the force meter (graduated up to 196 N) was attached (Figure 9).

case_images: A vertical upward force was applied to dislodge the denture while the patient was sitting in an upright position with the occlusal plane parallel to the floor and the digital force measurement gauge (digital force gauge device model 47544, Extech Instruments Corporation) held in the palm of the hand (Figure 10).
