Which occlusion concept is designed to create stable, even contacts on both sides during function?

• A. Balanced occlusion.
• B. Canine guidance.
• C. Group function.
• D. Edge-to-edge occlusion.

Answer: (A)

Balanced occlusion is designed to create stable, even contacts on both sides during function. In this approach, the teeth contact the opposing teeth on both sides not only in centric position but also during lateral and protrusive movements, so chewing forces are distributed across the arch and the denture or dentition remains stable rather than tipping or rocking. This bilateral contact is especially important for complete dentures, where maintaining stability during dynamic jaw movements prevents dislodgement and provides a smoother, more comfortable chew. Canine guidance, by contrast, relies on the canines to guide the mandible and disclude the posterior teeth in lateral movements, which reduces posterior contacts on the working side. Group function distributes load among several posterior teeth on the working side but does not create balancing contacts on the non-working side. Edge-to-edge occlusion involves incisal edge contacts that can lead to instability and wear without providing balanced bilateral contacts.
