Next-Generation Dental Implant Solutions and Specialized Implants Last update: 25. September 2025 Conventional (endosseous) dental implants are not applicable in all cases - particularly in severe maxillary bone loss in the upper jaw. This often affects precisely those patients who have already been declined due to the complexity of the procedure.

When conventional methods reach their limits, we use specially developed implants that are anchored in denser, stronger bone regions of the skull—such as the zygomatic bone (os zygomaticum), the nasal bone, or the region of the pterygoid plate at the skull base.

These implants are generally longer than conventional models, and their special shape enables firm anchorage in compact cortical bone for maximum stability and support. Thanks to this advanced approach, fixed provisional restorations can be placed immediately after surgery—bone augmentations such as sinus lifts and long waiting times are eliminated. Patients benefit from shortened healing times and can look forward to immediate transitional restorations and a definitive restoration after 3–6 months.

The use of such specialized implants is always preceded by thorough preparation. A digital impression and an AI-assisted 3D CBCT scan are created to enable precise analysis and exact treatment planning. In addition, we produce a true-to-scale, 3D-printed plastic model of the jaw, which is also digitally measured by AI-based image processing for preoperative visualization. The oral surgeon analyzes bone structure, density, and thickness as well as anatomical particularities that may influence the success of the implantation. This careful diagnostic workup is essential for a safe and successful treatment strategy and to avoid complications.

These procedures are used exclusively for full jaw reconstructions and for immediate, fixed dental restorations. They are particularly suitable when bone augmentation or sinus lift is not feasible for anatomical or medical reasons. The specialized implants can be combined with one another—each case is planned individually and digitally, and the optimally suitable implant is selected for the respective patient. These are highly advanced procedures that may only be performed by specially trained and experienced oral surgeons.

Pterygoid Implants – Posterior Implants

Pterygoid implants are specialized dental implants placed in the posterior maxillary region, where the bone is often too soft and porous for conventional implants.


These implants do not rely solely on the maxillary bone but are anchored in the solid bony structure of the so-called pterygoid plate at the skull base. This enables stable fixation without bone augmentation. They are ideal for patients with pronounced bone loss in the upper jaw, especially when multiple molars are missing.

They provide a stable foundation for bridges and fixed restorations—thus avoiding removable dentures. In combination with the All-on-4 method and two additional pterygoid implants, even greater stability can be achieved, making longer bridges with multiple teeth possible. They can also be combined with other conventional or specialized implants.

Trans-Sinus Implants – Lateral Implants

Trans-sinus implants are used when there is insufficient bone in the area of the maxillary sinus.

These longer implants pass beneath the membrane of the maxillary sinus and anchor in the denser bone above it. This eliminates the waiting time for bone healing after a sinus lift, as the implants are stably anchored in the hard cortical bone near the nasal cavity.

Trans-sinus implants provide an ideal solution for patients with significant bone loss who require reliable, long-term rehabilitation of the upper jaw with fixed dental restorations. These specialized implants are particularly suitable in cases of enlarged maxillary sinuses resulting from tooth extractions or anatomical conditions, when immediate fixed restorations are required. Here, too, combination with other implant types is easily possible.

Zygoma Implants – Lateral Implants

Zygoma implants are significantly longer than conventional implants and are anchored in the zygomatic bone, which is particularly dense and stable. They are used when there is too little—or no—bone left in the upper jaw to support conventional implants.


They provide a reliable, durable solution in cases of severe bone loss and make bone augmentation unnecessary in many cases. They are particularly often used in full reconstructions of the upper jaw to support a complete dental arch.

They can be used in a quad configuration (four implants) or combined with other conventional and specialized implants.

Transnasal Implants – Anterior Implants

Transnasal implants were developed for cases in which the anterior maxillary bone is very thin or no longer present. They are inserted at an angle and pass through the nasal cavity to anchor in solid bone, thereby providing secure support.

This technique makes it possible for patients with extreme bone loss in the anterior upper jaw to receive fixed, definitive teeth. They are most often used in combination with zygoma and/or pterygoid implants to stabilize the entire jaw. They offer an excellent alternative to complex surgical procedures or removable dentures.

Subperiosteal Implants

Subperiosteal implants are custom-made, specialized implant solutions that are used in over 90% of cases in the upper jaw when bone loss is so extensive that neither endosseous nor other specialized implants can be used. These implants are not anchored within the bone itself; instead, they are placed between the gum and the bone surface and precisely adapted to the contour of the bone. Stability is achieved through precise adaptation and fine titanium screws—with minimal stress to the surrounding tissue.

Each procedure is prepared by comprehensive, AI-assisted diagnostics, including detailed CT scans and 3D analysis. Based on this, the implant is custom-adapted to the patient’s anatomical conditions.

Close collaboration between the oral surgeon, dental technician, and our technical specialist team is crucial for an optimal functional and aesthetic outcome. In this case, the implants are manufactured individually using 3D titanium printing. The planning and production of the custom specialized implants, the surgery itself, and the dental laboratory restoration are carried out entirely in our own dental center.

In our clinic, we use subperiosteal implants as a last resort—especially for patients in whom several implantation attempts have failed or who suffer from extreme jaw atrophy. Even when bone augmentation or sinus lift is not possible for anatomical or health reasons, or when patients have already been declined multiple times due to the complexity of their case, they offer a reliable solution.

Despite the complexity of the procedure, subperiosteal implants provide a stable and functional alternative for restoring chewing function and aesthetics—even in the most difficult cases. They make it possible to regain fixed teeth when other options are no longer feasible.

Conclusion

Thanks to digital 3D planning, AI-assisted analysis, and in-house implant manufacturing, we offer precise, individually tailored solutions even under challenging anatomical conditions. By combining specialized implant types, state-of-the-art technology, and interdisciplinary collaboration, we enable rapid, stable, and aesthetically high-quality rehabilitation even in complex cases.
