- In August 23-25, 2007, the Scandinavian Society for Prosthetic Dentistry in collaboration with the Danish Society of Oral Implantology arranged a consensus conference on the topic 'Implants and/or teeth'. It was preceded by a workshop in which eight focused questions were raised and answered in eight review articles using a systematic approach. Twenty-eight academicians and clinicians discussed the eight review papers with the purpose to reach consensus on questions relevant for the topic. At the conference the consensus statements were presented as well as lectures based on the review articles. In this article the methods used at the consensus workshop are briefly described followed by the statements with comments.

- The aim of this study was to evaluate the number of possible sites for cylinder implants in an epidemiological sample of adult individuals and to compare these results with those from a similar inventory performed 10 years earlier. This study, which comprised individuals 20-70 years old, is part of two larger epidemiological dental studies of individuals from the community of Jönköping, Sweden, performed in 1983 and 1993. Random samples of 579 and 575 individuals respectively were examined and classified according to the Eichner index. The radiographic examination included an orthopantomogram and a full-mouth intra-oral examination. Only existing spaces anterior to the second molars were considered as possible implant sites. Cylinder implants with a diameter of 3.75 mm and a length between 7 and 20 mm were plotted on the radiographs. Result: The most striking result from this study was the reduction by almost a half of the total number of possible implant sites between 1983 and 1993. A certain proportion of existing tooth gaps had been treated with conventional fixed prostheses, usually in small tooth gaps, and this tendency had increased between 1983 and 1993. The need for implants in the anterior frontal region was small but constant (less than 1%) in 1983 and 1993. In the future, implants will be a treatment option in young individuals, most likely in cases of trauma and tooth agenesis. Further it may be assumed that implant treatment in edentulous jaws will continue to increase in relative terms, i.e. the percentage of edentulous jaws that have been treated with implants will increase. In absolute terms, however, the frequency of the treatment will decrease because fewer individuals will be edentulous. Instead, the proportion of partially dentate subjects treated with implants will increase.

- Implant treatment is nowadays requested as an alternative mode of treatment for both total and partial edentulousness. The purpose of the study was to assess the maximum number of possible implant sites in a group of adults. The study material comprised 579 persons divided into the age-groups 20, 30, 40, 50, 60 and 70 years. Based on radiological examination, the subjects were grouped according to Eichner's index. They comprised both dentate and edentulous individuals. Templates, marked with cylinder implants of different dimensions, were placed over edentulous regions. The possible number of cylinder-shaped endosseous implants that could be placed anterior to the second molar was assessed in relation to bone availability and anatomical structures. Gaps treated with fixed bridges were not registered. Altogether 1,048 presumptive fixture sites were marked, of which 78% in the age-groups 60 and 70 years. Eichner groups C 1-3, which comprised the edentulous persons, constituted 12% of the subjects and accounted for 57% of the possible number of implants. All edentulous mandibles and 70% of the edentulous maxillae were judged suitable for placement of implants. On average 5.5 and 5.8 sites were marked per edentulous maxilla and mandible, respectively. Groups B1-4 comprised 21% of the subjects and accounted for 37% of the implants. It is discussed that implant treatment in totally edentulous jaws will increase in relative terms in Sweden as in other Scandinavian countries, i.e. the percentage of edentulous jaws treated with implants will increase. In absolute terms, however, the treatment will probably decrease owing to a marked decrease in the number of edentulous individuals. The future need for implant treatment in the residual dentition will probably increase but it is difficult to predict by how much.
