Correct answer: A — Mark the contact and selectively grind the interference
Explanation lettering: C = shown as B · D = shown as C · B = shown as D
The correct answer is A. A premature posterior contact in a newly fitted complete denture can destabilise the bases and cause discomfort during closure. Identify the interference with articulating paper and selectively reduce the marked interfering tooth surface, reassessing until centric occlusion is stable and even. Processing-related occlusal errors are recognised to affect complete-denture retention and stability and require adjustment. Remaking the dentures (B) is disproportionate for an isolated occlusal error. Allowing the patient simply to adapt (C) leaves the interference uncorrected; dentures do not reliably “settle” into a correct occlusion. Adding acrylic contralaterally (D) or grinding the unaffected left side (E) creates or worsens an occlusal discrepancy rather than removing its cause.
