Abstract

In fixed prosthodontic treatment of the maxillary anterior region, where high esthetics are required, it is crucial not only to achieve a successful prosthesis but also to form symmetrical and natural gingiva. To achieve esthetic gingiva, it is necessary to adjust the subgingival contour of the temporary prosthesis or to modify the base of pontic. However, during the transition from temporary to definitive prosthesis, the conventional method of removing the temporary prosthesis and taking an impression after gingival retraction often fails to accurately reproduce the gingival profile. In such cases, the gingiva is arbitrarily trimmed on the model to fabricate the definitive prosthesis, which reduces the predictability of esthetic treatment outcomes. This case report introduces methods to transfer the subgingival contour and the pontic base formed with the temporary prosthesis to the final model and definitive prosthesis through two cases.
