For patients with a perfectly healthy condition of their jawbone, holding titanium implants will not constitute any problems. Securing dentures to a jawbone of a decent size, will be a simple task. But if the jaw is in a far stage of atrophy, there is not enough qualitative bone left for a strong anchorage of implants.
Extreme atrophy of the jaw bone, in maxilla or mandible, requires an alternative solution. AMSJI®™, or "Additively Manufactured Subperiosteal Jaw Implant", presents an elegant alternative for bone grafts or quad zygoma implants, for patients with Cawood & Howell Class V to VIII bone atrophy.

CADskills offers a solution designed for each patient individually, starting with CT scan of the jaw and scanning prosthesis in occlusion and 3D printing to our biocompatible titanium and 3D printing temporary prosthesis.
Biofunctionalization for optimal biocompatibility and scaffolds provide secondary fixation in addition to primary screw fixation. The screws are placed in the place where the bone is of the highest quality and does not absorb, i.e. in the zygomatic support surfaces and in the frame of the piriform opening.
The generic AMSJI implant is topologically optimized according to predefined standards. Each implant undergoes an individual Finite Element Analysis to ensure the strength of AMSJI®™. This allows the posts to be removed if needed to avoid infections and peri-implantitis. The patient never ends up in a situation that is worse than before the implantation.
The operation can be performed under local anesthesia and takes less than 2 hours; This is because the AMSJI implant fits the patient's jawbone perfectly. CADskills supplies a fully equipped instrument set together with the implants. The patient returns home with a temporary functional denture and a bright smile, in one go!
After two months, the temporary prosthesis is replaced by the final restoration. The final denture can be fixed or removable. CADskills offers a hybrid bridge or twin structure. For patients whose jawbone is completely healthy, keeping titanium implants does not cause any problems. Attaching the braces to an appropriately sized jawbone is a simple task. But if the jaw is far into the atrophy stage, there is not enough quality bone left to anchor the implants strongly.
Extreme jaw atrophy in the upper or lower jaw requires an alternative solution. AMSJI®™ or "Additively Manufactured Subperiosteal Jaw Implant" offers an elegant alternative to bone grafts or quadrizygoma implants for patients with Cawood & Howell classes V-VIII bone atrophy.
