Papilla regeneration by noninvasive prosthodontic treatment: segmental proximal restorations.

Bonded segmental proximal restorations, whether direct or laboratory fabricated, can be added to selected aspects of a tooth utilizing the acid-etch technique with no macromechanical preparation. When properly executed the prosthetic supplements guide and support newly regenerated papillae in deficient interproximal aspects. Although they are overcontoured, the properly finished and polished convex intracrevicular areas of the restorations will not have adverse effects on the tissues. When overcontoured restorations are limited in the interproximal space, compression and relief of the gingival fibers results. Alternately, any overcontouring of the labial aspects might stretch and cause overtension to the gingival fibers and result in iatrogenic damage to the periodontal support structures. The controlled, intentional, overcontoured proximal restorations and the adjoining soft tissues can easily be maintained through regular oral hygiene measures, for healthy, long-lasting service.
