Treatment of extremely atrophic maxilla using the AMSJI a patient-specific implant (PSI)

The 3D technologies based on CT/CBCT imaging combined with interactive surgical planning softwares, stereolithographic anatomical models and CAD-CAM procedures, can be very useful in the implant treatment of advanced maxillary bone atrophy. The therapeutic options for Cawood-Howell IV, V, VI, in our experience, include Bone Grafting, Zygomatic Implants and a new High-Tech Sub-Periosteal Implants: the AMSJI.

The use of zygomatic implants has proven to have a high success rate and is emerging as an alternative treatment to the large bone reconstructions of the maxilla. Many works show that, in addition to the intra-sinus path of the original protocol (Branemark 1988), different variants can be used, and the implants can be inserted in the zygomatic body with different trajectory based on accurate anatomical evaluations. The surgeon, however, is forced to make accurate assessments of the entrance point, path and exit point of the zygomatic implants during the surgery. To overcomes these problems we have developed a surgical protocol with the aim of providing tools for study and control of implant placement and have a tool to transfer the surgical and prosthetic project to the surgical phase. We believe that this protocol can improve safety and reduce both surgical and prosthetic risks related to zygomatic implant surgery.The additively manufactured sub-periosteal jaw implants (AMSJI) rapresent an alternative solution to zygoma implants or to extensive bone grafting.

The concepts of AMSJI are unique in many ways and uses the most modern technologies like: 3D-printing, finite element analysis, topological optimization, to create a custom-made sub-periosteal implant. This customized, prosthesis-driven reverse-engineering represents a therapeutic alternative implant approach avoids the problems related to bone grafting and to zygomatic implants and provides immediate functional restorations.
