Webinar purpose

Subperiosteal implants are an old concept, because shortly after the discovery of vitallium as a corrosion resistant biomaterial, already in 1938 the Swedish dentist Gustav Dahl has described and applied the first subperiosteal dental implant for stabilization of a lower denture. The idea has spread quickly to America and worldwide. At that time surgeons have observed, that circumferential wires used to fix the subperiosteal implants, became loose after some time, because the physiological jaw atrophy continued. Furthermore two surgeries were required, one for impression taking and one for insertion of the structure. The method was deemed a failure in the later decades, because many implants became unstable due to jaw resorption and large jaw defects occurred. The new digital technology for IPS Implants Preprosthetic changes this view on subperiosteal implants. Due to additive manufacturing by selective titanium laser melting according to CT scan data only one surgery is required. Besides the fixation of the subperiosteal implant can be placed in jaw areas which don’t resorb. As a result the new technology can be applied as a bone augmentation free method even in cases with major bone loss due to tumor therapy or due to advanced jaw atrophy. In a small clinical series of 5 cases the intraoperative fit of the subperiosteal implant has always been perfect. The dental prostheses could be safely delivered intraoperatively at the time of implant placement, because the implant is fixed with 2.0 mm bone screws. 4 out of 5 implants survived with an observation time of 11 months in average and 23 months in maximum. The achievable primary stability and immediate function was unsurpassed by any conventional implant technologies.
