A cast partial denture replacing teeth 3.5 - 3.8 and 4.5 - 4.8 was permanently relined with acrylic resin. At the delivery appointment, when the rests of the framework are fully seated on the abutment teeth, the denture base does not contact the supporting tissues. The most likely cause of the problem is
excess pressure was placed on the denture base area during the impression procedure.
the patient’s tissues have remodelled.
excess pressure was placed on the rests during the impression procedure
the denture reline resin shrunk during polymerization
