Abstract
When a tooth adjacent to implant has coronal damages caused by severe dental caries or fracture, the clinical crown lengthening by forced eruption makes it possible to get esthetic restoration due to the prevention of alveolar crestal bone resorption and loss of interdental papilla. A 54-years-old male patient wanted prosthetic treatment because his anterior 3 unit bridges had fallen out. A right maxillary central incisor showed mild dental caries but a right maxillary canine lost most clinical crowns. Forced eruption combined with a gingival fiberotomy of a right maxillary canine was performed for 1 month after the dental implant had been simultaneously placed with bone grafts on a right maxillary lateral incisor. About 5 months after implant placement, 2nd surgical operation was performed. The provisional restorations were adjusted to make esthetic gingival contour for 8 weeks. The porcelain fused gold restorations were fabricated and set. The patient was satisfied with the final restorations in esthetic and functional aspect. (J Korean Acad Prosthodont 2011;49:80-6)
