Some issues related to evidence-based implantology

ABSTRACT

This article reviews relevant dental literature to answer some frequent questions related to evidence-based implantology. There are hundreds of implant systems on the market, but the majority lack clinical documentation. Recommended number of implants for full-arch fixed prostheses is four or five in the mandible but at least six in the maxilla. Less expensive implant-retained overdentures make implant treatment available to a greater portion of edentulous subjects. Mandibular overdentures on two implants, and even one implant, have shown excellent long-term outcomes. In the maxilla, less than four implants are not recommended for good results. Single implant restorations have good prognosis, but placement of the implant should be postponed until adulthood. Osseointegrated implants have revolutionized clinical dentistry. However, in a global perspective, implants make up only a small part of all prosthodontic treatment. Knowledge and skill in conventional prosthodontics must be maintained as it will remain the most common part of the specialty.

Mentions: The original Brånemark protocol suggested 6 implants for an ISFDP in both the edentulous mandible and maxilla, with excellent long-term results.[1011] The 5-year implant survival of ISFDP has been reported to be about 95%; results that were even higher when studies after the year 2000 were analyzed.[1213] In the mandible, the recommendations are now four or five and the reduced number has been shown to give as good results.[14] Even 3 implants for a mandibular ISFDP have been tried, but only 1-year results have been presented.[15] In the maxilla, the original recommendation of six implants seems still to be valid. Some authors suggest that the number of implants should be greater (8–12) for “security reasons.” There is no evidence to support this opinion; however, for the manufacturers, it is of course a desirable suggestion. Numerous studies have demonstrated excellent functional results with four to six implants placed in the anterior region for support of full-arch implant-supported fixed prostheses.[16] Cantilevers make posterior implants unnecessary [Figure 1].
