The document discusses how orthodontic treatment can be used to improve periodontal health and outcomes for dental restorations in several ways: by uprighting or intruding teeth to create better bone architecture and reduce periodontal pockets; by aligning teeth to improve hygiene and reduce trauma from malocclusions; and by moving teeth to expose margins or increase keratinized tissue for restorations without gum reduction. Several case examples are provided to illustrate these techniques.
