Correct answer: E — To prevent denture base displacement during eccentric jaw movements by maintaining simultaneous bilateral occlusal contacts
Bilateral balanced articulation in complete dentures maintains simultaneous contacts on both sides in all excursive positions (protrusive and lateral). This bilateral contact prevents tipping or rocking of the denture bases during eccentric movements, maintaining stability and retention. This is fundamentally different from natural dentition occlusion (where canine guidance or group function deliberately separates posterior teeth during excursion). Balancing contacts are achieved by adjusting the compensating curve, cusp angle, and condylar guidance.
