Periodontal Regeneration and Treatments

The following periodontal/restorative interrelations should be observed: 1. Deflective contours and/or overcontouring should be avoided in the cervical third and the interproximal surfaces of tooth restorations. 2. Overcontouring of the interproximal region is common and harmful to periodontal health. 3. Adequate tooth reduction at the gingival margin and interproximally provides for restorative materials and lessens the potential for overcontouring in these critical regions. 4. Fluting or barreling of exposed furcations eliminates plaque shelves and promotes accessibility for hygiene. 5. Minimal disruption within the intracrevicular space during tooth preparation allows a more predictable, favorable periodontal response to satisfactorily contoured restorations.
