<prompt> After relining complete denture for a patient, operator observes that patient has difficulty in biting with dentures. What could be the most possible reason?Altered neuromuscular perceptionAltered centric occlusionToo retentive denturesNone of the above  <response>: During relining procedure, utmost care should be taken, so as not to alter centric occlusion. A precaution for this would be, placement of both dentures while relining and working on one denture at a time. Changed centric occlusion will result into faulty occlusion, which will then require either repeating procedure or by grinding of interfering contacts, if discrepancy is small.
