Immediate loading of dental implants in the partially edentulous patient has not been investigated widely. Immediate loading requires immobilization of the implants by the superstructure (Ledermann, Brunski). An animal study was performed to evaluate the clinical success and the bone metabolism during the course of osseointegration on 12 implant borne bridges. Three month after tooth extraction implant insertion and prosthetic treatment was per-formed. 29 implants out of 62 had an insertion tor-que (IIT) above 35 Ncm. The average insertion tor-que of the implants per bridge (BIT) were determined. If the BIT was higher than 35 Ncm the bridges were successful after 3 month of loading. The histological findings of loaded and unloaded implants will be presented. The procedure with pre-fabricated auxiliary parts allows fabricating a bridge reconstruction during one appointment.
