  9. 9. Evaluating the retention and stability of denture » Retention: by applying dislodging forces as attempting to remove the denture - Posterior palatal seal is checked by gently pressing the anterior teeth perpendicular to the path of insertion, if adequate we can feel the resistance. - Stability: using the f1nger’s pad, applying pressure on the occlusal surface at the premolar region on each side alternatively. If that caused the denture to tilt (rock) and dislodge from the ridge at other side, this may indicates that there is a problem in stability (as if the teeth was positioned buccally). - Anterior seal is checked by pulling against the path of insertion.
