79. Why is bilateral balanced occlusion preferred in most patients when designing and occlusal arrangement for complete dentures?
Balanced occlusion is preferred because it provides stability during parafunctional movements. In bilateral balanced occlusion, all posterior teeth are in contact, with no anterior contact, when in centric relation. Also, during excursions, there are at least 3 stable contacts widely distributed around the arch. This is preferable over other forms of occlusion where in balancing and protrusive positions there would be separation of the denture teeth in the posterior regions leading to tipping of the dentures, which would be disadvantageous in the patients exhibiting parafunctional grinding habits
