The connection between implant and superstructure (connecting elements) is of upmost importance. For fixed dental prostheses, these attachments comprise abutments, which enable screw retention or cementation of the restoration. In general, screw-retained superstructures on multiple implants have a tendency toward more technical complications, such as screw loosening, whereas cemented superstructures bear the risk of biological complications such as periimplant mucositis. Aspects influencing selection of the appropriate abutment in the anterior and posterior region as well as aspects of treatment with single crowns or fixed dental prostheses are discussed. Treatment concepts for removable dental protheses differ in terms of primary or secondary splinting as well as static or dynamic transmission of mastication forces from the superstructure to the implant. Correlated to the number and distribution of implants, various attachments such as double crowns, bar retainers, magnets, ball attachments, or Locator™ attachments are discussed.
