The extremely atrophied maxilla is one of the greatest challenges in the stomatognathic system with regard to dental rehabilitation. The use of conventional dental implants in combination with abutment, inlay and overlay osteoplastics or also with special implants such as the Zygoma implant can create a satisfactory solution here, but is tied to a treatment period that may well require a calendar year. With the Individual Patient Specific-Implant-Preprosthetic, a new treatment form of the patient-specific scaffold implant manufactured in 3D metal powder printing by the laser melting process for immediate dental rehabilitation is presented, which as a primarily functionally stable implant anchored by multi-vector osteosynthesis represents an important supplement to conventional dental implants. It can be used as an alternative when the morbidity, invasiveness and duration of conventional surgical-prosthetic therapy no longer appear adequate, especially when such therapy has previously failed, particularly in the case of large defects such as those often found in wounded patients.
