For a fully dentate patient, which type of occlusal scheme is preferred because it provides lateral excursive guidance that discludes all posterior teeth, minimizing lateral forces?

Canine guidance (canine-protected occlusion) is the preferred occlusal scheme for the natural dentition. During lateral excursions, the canine tooth on the working side contacts and guides the mandible, resulting in immediate disclusion (separation) of all posterior teeth. This protects posterior teeth from harmful lateral forces because canines have: favorable crown-root ratio, dense cortical bone support, proprioceptive advantage (high density of mechanoreceptors in periodontal ligament), and single-rooted design optimized for lateral forces. Group function (multiple teeth contact during lateral excursion) is used when canines are unsuitable for guidance. Balanced occlusion (bilateral posterior contact in excursion) is used for complete dentures.
