AMSJI

AMSJI

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.

Product specifications

CADskills offers the solution, designed for every patient individually, starting from a CT-scan of the jaw and the scanprosthesis in occlusion, and 3D printed in our biocompatible Titanium and 3D print temporary prosthesis.

Biofunctionalization for optimal biocompatibility and scaffolding assures secondary fixation, in addition to the primary screw fixation. Screws are placed where the bone is of best quality and will not resorb, namely in the zygomatic buttresses and the frame of the piriform aperture.

The generic AMSJI implant is topologically optimized according to pre- defined standards. Every implant is individually subjected to Finite Element Analysis, to assure the strength of the AMSJI. This results in the possibility to remove posts if necessary, to be ahead of infections and periimplantitis. The patient will never end in a situation that is worse than before implantation.

The surgery can be performed under local anaesthesia and takes less than 2 hours; this because the AMSJI implants fit perfectly on the patient’s jawbone. CADskills delivers a completely equipped instrument set, together with the implants. The patient returns home with a temporary functional denture and a bright smile, in one single session!

After two months, the temporary prosthesis is replaced by a final restauration. The definitive denture can be fixed or removable. CADskills offers a hybrid bridge or a double structure.
