In the last decade, the replacement of old PFM restorations has been a common dental procedure, especially on the anterior regions. Gingiva conditions in most re-treatment cases are not healthy with the old restorations due to ill-fitting margin, improper tooth reduction and poor oral hygiene. Practitioners must carefully evaluate and manage periabutmental gingiva for final restorations. The role of provisional restoration became a major clinical concern at this point. Well-fabricated provisional restorations with precise-fit margin and proper anatomy are critical for achieving good gingival health. Thus, the key of success in replacing old PFM crown depends on the proper tissue management by precise provisional restorations
