Correct answer: D — To achieve bilateral balanced occlusion by compensating for the Christensen phenomenon during protrusive and lateral excursions

The compensating curve in complete denture prosthetics is a curve (curvature of the occlusal plane) built into the arrangement of posterior denture teeth to achieve bilateral balanced occlusion. It compensates for the separation of posterior teeth (Christensen phenomenon) during protrusive and lateral mandibular movements. According to Thielemann's formula, the compensating curve is influenced by the condylar guidance angle, incisal guidance angle, and cusp angle. Without this curve, the posterior teeth would separate during excursions, destabilising the dentures.
