Loading of Craniofacial Implants

چکیده
Osseointegrated extra-oral implants have been used effectively as the anchoring points for facial prostheses. The success of the extra-oral implants is dependant upon the continuing health of the bone-implant interface, and although the success rate of extra-oral implants is high there are still recorded failures in all the bones of the face. One of the factors that is believed to influence the health of the bone-implant interface is the type and magnitude of loads applied to the implant and consequently the strains induced in the supporting bone. The mechanostat theory by Frost [1] attempts to relate the response of bone to various levels of strain. In this theory, the minimum effective strain for bone remodeling (the normal turnover of bone) is between 100 and 300 .

BACKGROUND Reconstruction of craniofacial defects becomes complex when dental implants are included for functional rehabilitation. We describe a fully 3-dimensional (3D) digitally planned reconstruction of a mandible and immediate prosthetic loading with a fibula graft in a 2-step surgical approach. METHODS A 54-year-old man had development of osteoradionecrosis of the mandible. The resection...

متن کاملClinical Parameters and Crestal Bone Loss in Internal Versus External Hex Implants at One Year after Loading
Introduction: The survival of an implant system is affected by the choice of antirotational design, which can include an external or internal hex. Implant success also is affected by the maintenance of the crestal bone around implants. The aim of present study was to evaluate the crestal bone loss and clinical parameters related to bone loss in patients loaded with an external or internal hex 3...
