Screw-Retained Crown

A screw-retained crown is a single-unit implant restoration designed to attach directly to the implant. The milled crown is bonded to a titanium base (Ti-base), which connects to the implant using a prosthetic screw.

Supplemental Information

Indication

Screw-retained crowns allow retrievability of the restoration if screw loosening occurs or if removal is needed. They also eliminate excess cement, reducing the risk of peri-implant inflammation and implant failure.

Contraindications

Implant platform placed excessively subgingival (>3 mm) which may create over contoured restorations that impinge on the gingiva and cause soft-tissue irritation
Severe implant angulation resulting in a facial screw access in anterior teeth
Limited restorative space preventing proper Ti-base and crown material thickness
Implant positioned outside the prosthetic envelope, preventing ideal screw access placement

Clinical Advantages

Retrievable for maintenance, hygiene access, soft-tissue evaluation, repair, or screw replacement without cutting the crown. Eliminates the risk of excess cement at the implant platform, which is particularly important for subgingival implant restorations.

Gold-Tone Ti-Base Option

Inclusive^® Ti-bases can be anodized to a gold tone to help mask the underlying titanium color and improve esthetics in thin tissue or anterior cases. Available for Inclusive Ti-bases only.

Space Requirement

Interocclusal: Minimum 5.5 mm intra-occlusal space from the implant platform to the opposing dentition
Interproximal: Minimum 2.0 mm space from the implant platform to adjacent teeth for proper emergence profile and crown contouring

Implant Access Hole Considerations

Anterior: Screw access may emerge on the facial surface depending on implant angulation. If this occurs, a custom abutment with a cement-retained crown may be recommended for improved esthetics
Posterior: Facial access is generally acceptable and the screw-retained restoration proceeds as designed
Provide the requested tooth shade

Maximum Units / Bridge Design

There is no strict maximum number of units if the prosthetic design follows the BruxZir Rule of 27 for connector strength and sound biomechanical principles. Cantilevers should not exceed half of the anterior-posterior (A-P) implant spread, and Ti-bases are typically not the limiting factor when these guidelines are followed.
