Knowledge of malocclusion supports comprehensive dental hygiene care.

Occlusal assessments are often missed or neglected by dentists and dental hygienists. This short communication discusses how these assessments can be implemented through 4 planes of space: anterior-posterior/anteroposterior, vertical, transverse, and perimeter. Expanded occlusal knowledge can improve the referral process for early preventive care. A chairside guide has been defined for dental hygienists to conduct a systematic occlusal exam.
