Abstract
Patient: The patient was a 52-year-old female who complained of esthetic disturbance of the maxillary anterior teeth. Abutment teeth of a 4-unit upper anterior fixed-partial denture were diagnosed as pyorrheal and extracted. As a result, four upper incisor teeth were consecutively missing. She obstinately wanted to restore fixed restoration, and she did not to prepare approximal teeth. For the reasons stated above, implant restoration was selected for intermediate edentulous ridge.
Discussion: When restoration is done with fixed partial denture, preparation of the tooth substance is indispensable. In this case, implants were used for abutments, and approximal intact teeth were saved.
Conclusion: Approximate teeth for intermediate defects were preserved by shift from the conventional fixed partial denture to the implant restoration. Because the patient was satisfied esthetically and functionally, implant restoration was shown to be effective treatment in this case.
