Treatment planning: implant-supported fixed partial denture


Dental implants have become the first treatment option for most edentulous patients and in particular for partial restorations. This is due to the favorable long-term results and the opportunity to deliver a prosthetic restoration with minimal risk, compared to a conventional approach.

Nevertheless, some controversies remain concerning the overall prosthetic decision: distribution of implants, cantilevers, implant/natural tooth connection, and screw-retained or cemented restorations.

The general prosthetic goal is to create an overall reliable structure consistent with a comfortable function (biomechanics), acceptable esthetics, and with minimum morbidity and cost.

Opinions based on conventional prosthetic treatments experience are not always reliable, as implant-supported denture concepts follow specific rules, mainly related to the osseointegration process.


Compared to most conventional restorations, implant-supported FPD represents a less invasive prosthetic treatment with a reduction of the overall risk (Pjetursson and Lang, 2008) (Table 27.1). This is partially due to the possibility of increasing the number of abutments.

Conventional tooth-supported FPD 93.8 89.2
Cantilever FPD 91.4 80.3
Implant-supported FPD 95.2 86.7
Combined tooth-implant FPD 95.5 77.8
Implant-supported single crown 94.5 89.4
Resin-bonded bridge 87.7 65

Financial costs and anatomical limits can represent barriers which are not easy to overcome, and conventional restorations can then be considered.


Implant-supported FPD, when possible, is the treatment of choice for partially edentulous patients in the following situations:

  • healthy adjacent teeth
  • intact adjacent tooth restoration
  • posterior reduced arch
  • extended edentulous segments.
