Labor Screw and cement Retained
(1) Cemented Implant Crown/bridge
Cement-retained implant-borne restorations offer several advantages, including the elimination of unesthetic screw access holes and greater resistance to porcelain fracture. Standard crown & bridge procedures can also be used in most situations. However, excess cement left behind inadvertently is a major problem and can result in soft tissue damage, bone loss and/or chronic inflammatio.
The main advantage of the screw-retained crown is retrievability. The crown is not only recoverable, but no damage occurs upon removal of the crown. In the event of loosening or fracture, the crown can easily be removed. Cleaning, screw replacement and assessment of surrounding tissue is also possible.
