Failing four-unit maxillary fixed partial denture: part 1.

In this two-part treatment planning series, the case of a 54-year-old woman with a failing four-unit fixed partial denture (FPD) is presented. In Part 1, pretreatment strategies, e.g., use of intra- and extraoral photographs, analysis of periapical radiographs, and examination of occlusal and periodontal status, are discussed. The advantages and disadvantages of three treatment options--removable partial denture, tooth-supported FPD, and implant-supported FPD-are presented. In Part 2, to be published in the next issue, the treatment selected will be revealed and the rationale governing the decision will be discussed.
