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: IODs in the maxilla have not been as successful as in the mandible. Maxillary IODs present a number of different challenges compared to the predictable benefits of mandibular two-IODs.[3132] To use a two-IOD in the maxilla cannot be recommended. However, systematic reviews have concluded that maxillary overdentures on four or more implants in a splinted construction provide high survival (>95% for the 1st year) both for implants and overdentures. Long-term results regarding maxillary IODs are still rare and when available often inconsistent.[33] However, following the recommendation to use four or more implants splinted with a bar system a maxillary overdenture can be a successful treatment option [Figure 3; Reprinted from Feine and Carlsson[18] with permission]. Using four or less implants and a ball attachment system is in general less successful.[2032]
