Screw-Retained Crowns

Screw retained implant crowns from Crown World Dental Lab. Designed for retrievability, precision fit, and long-term success with fast turnaround times for dentists.
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​
