We report 13 years of experience with SHORT® and extra SHORT® Bicon implants in the extremely atrophic maxilla, mandible and in Fibula grafts. All patients have been treated with CAD/CAM produced metal free hybrid fiberglass-resin TRINIA® prostheses. Our cohort includes by now 67 patients, mostly treated with 5.0 mm extra SHORT® implants. Only 4 have been not osseointegrated or lost. In accordance with Wolff’s law, we observed bone gain even in the implants that were splinted. Due to these successful results, we changed our restorative method of supporting prostheses from four implants to three implants. In the maxilla, we place the middle implant in the incisive foramen and the nasopalatinal canal. In very atrophic maxilla cases we also insert sometimes extra SHORT® implants into the Tuberosity of the maxilla. In conclusion we can state that the SHORT® and extra SHORT® implants we have used, should be functional loaded. Some implants even show crestal bone gain under functional load. In the fibula grafts we observe distinct bone remodeling around the implants and of the whole transplanted fibula cortex due to functional load.
