What causes impression pressure on the retromolar pad of dentures?
Primary cause of exerting a strong impression pressure on the retromolar pad is the impression tray frame, and secondary cause is a pressurized impression taking with a low flow and high density material or compound (Fig.11-13). Fig.8 Mandibular denture with suction.
