Fabrication of a Retrievable Cement- and Screw-Retained Implant-Supported Zirconium Fixed Partial Denture: A Case Report

Abstract

It can be difficult to achieve superior esthetics in implant-supported fixed partial dentures (FPDs). Zirconia ceramics with high flexural strength and esthetic can be treatment options for implant-supported FPDs. This article describes a simple and reliable method to fabricate a retrievable cemented implant-supported zirconia FPD.

Torque loss under mechanical cycling of long‐span zirconia and titanium‐cemented and screw‐retained implant‐supported CAD/CAM frameworks

“…The removal of the prosthesis and abutment without a crown remover is therefore enabled in the need of repair (Uludag et al. ). Baig et al.…”

“…and the prosthesis, avoidance of the use of provisional cements, and ease of intentional removal of the prosthesis to clean excess cement. Uludag et al (2008) presented a clinical case to demonstrate the technique with a retrievable cement-and screw-retained implant-supported zirconium FDP luted with conventional cementation. In this case, the screw access channel had been maintained even in the final restoration, thereby enabling intentional removal of the entire prosthesis by screw removal.…”

“…In this case, the screw access channel had been maintained even in the final restoration, thereby enabling intentional removal of the entire prosthesis by screw removal. The removal of the prosthesis and abutment without a crown remover is therefore enabled in the need of repair (Uludag et al 2008). Baig et al (2009) proposed a modification of the technique because of the difficulties when angulated implants are present.…”

The effect of different surface treatments on the bond strength of a gingiva‐colored indirect composite veneering material to three implant framework materials

“…; Canullo ; Uludag et al. ). Screw‐ and cement‐retained implant‐supported FPDs are now frequently fabricated from zirconia due to the ability to design and manufacture a one‐piece zirconia substructure.…”

Effect of screw access hole design on the fracture resistance of implant‐supported zirconia‐based restorations

“…A method for enhancement of screw access hole accessibility in cemented‐retained implant‐supported restorations is defined as the combination implant crown in which a crown with a screw access hole is cemented . This retention system combines some advantages of both systems such as lower cost of abutments and routine laboratory process of cement‐retained restorations and retrievability of screw‐retained restorations . Comparably, this method can be used for zirconia‐based restorations …”
