ZL anchors are rigid, extracoronal attachments that reliably retain removable restorations to the residual dentition. The ZL ANCHOR SYSTEM with its exchangeable, activatable patrix offers interesting planning options and designs for prosthetic restoration of bilateral free-end and bounded saddle dentures as well as removable bridges. Laboratory technicians will appreciate the simple, precise technique. The slightly conical shape of the patrix makes it easier for the patient to fit the denture and promotes regular hygiene.
