Extreme Maxillary Atrophy Treated in a Single Surgery Using HUG® Subperiosteal Implants

This 81-year-old patient presented with severe maxillary bone resorption.
Instead of performing bone grafting procedures followed by conventional implant placement, which would have required approximately one year of treatment, a custom-made HUG® subperiosteal implant was used.
The patient was treated in a single surgical procedure and was able to leave with a fixed, definitive 14-unit full-arch bridge, consisting of a machined titanium framework and composite resin teeth, screw-retained onto the implant’s multi-unit abutments.
The implant structure was covered with a biomaterial and a regenerative membrane to promote tissue integration and help prevent soft tissue recession, which is the most commonly reported complication associated with subperiosteal implants.
This protocol was performed by Dr Antoine Diss and Dr Laurine Birault at Arenas Dentistes, Nice, France.
