Screw-Retained Hybrid Denture

The Screw-Retained Hybrid Denture is a type of prosthesis securely attached to implant abutments through a specialized connection system. This design enhances stability, chewing efficiency, and comfort for the wearer. The product combines the convenience of traditional removable dentures with the strength of fixed implant restorations.

Benefits and Material Evaluation

• Denture Base:

-  High-quality Acrylic Resin (PMMA): Widely used due to its high esthetics, lightweight nature, and ease of adjustment.

- Metal Base (Chrome-Cobalt or Titanium): Strong, thin, and highly resistant to force. Indicated in cases requiring enhanced durability or when designing bar-retained dentures.

• Denture Teeth: Made from composite or acrylic resin, offering good esthetics and easy customization of color and shape.

• Abutment and Attachment Systems: Made of titanium and dental alloys with high biocompatibility. Attachment types such as Locator™, ball, or bar systems are precisely engineered to ensure durable connections and adjustable retention force.

Technical Specifications

• Attachment Types:

- Ball Attachment (O-ring): Retention force ~5–8 N.

- Locator Attachment: Retention force adjustable from ~1.5 to 6 N using colored inserts.

- Bar Attachment: High retention, excellent force distribution across multiple implants. The choice of attachment depends on clinical indications to ensure a balance between retention and ease of removal.

• Minimum Vertical Space Requirement:

- Ball-retained: ~10–12 mm.

- Locator-retained: ~8–10 mm.

- Bar-retained: ~14–16 mm.

• Production time in lab: 5–7 working days
