Abstract: Device including implant type support defining constraint axis, connector operatively interconnecting the support and dental prosthesis along the constraint axis, defining a constraint configuration having firmly constrained support and prosthesis, and a graft including first portion extending mainly parallel to constraint axis, a body including guide extending along transverse or slanted direction relative to constraint axis and cavity extending parallel to constraint axis for housing the first portion when connector is in the constraint configuration, obstructer including slider compliantly housed within the guide.
