Which occlusal scheme is designed to ensure bilateral contacts, promoting stability in dentures?

• A. Bilateral Balanced Occlusion
• B. Mutually Protected Occlusion
• C. Group Function
• D. Anterior Guidance

Answer: (A)

Bilateral balanced occlusion is meant to produce simultaneous contacts on both sides of the arches in centric relation and during excursions. This bilateral contact pattern distributes chewing forces across the denture bases, helping resist tipping and improving stability and retention during function. Other schemes emphasize different goals: mutually protected occlusion prioritizes anterior disocclusion to shield posterior teeth, group function focuses on contacts on the working side only, and anterior guidance uses the front teeth to guide movement without guaranteeing bilateral posterior contacts. So, for dentures, the design that ensures bilateral contacts and stability is bilateral balanced occlusion.
