Internal Hex Ti-Base CAD/CAM

Understanding Internal Hex Titanium Bases (Ti-Base Abutments)

A titanium base—commonly called a Ti-Base abutment—is a precision connector that joins an internal-hex dental implant to a digitally designed crown or bridge. It forms the foundation of modern CAD/CAM implant workflows, combining titanium’s mechanical strength with the accuracy of digital design.

How Ti-Bases Work

• The Ti-Base screws directly onto the internal-hex 2.42 / 2.43 mm implant connection, creating a secure mechanical interface.
• A custom-milled zirconia or ceramic restoration is bonded or cemented onto the Ti-Base to complete the prosthesis.
• The assembly is torqued to the manufacturer’s value (typically 30 Ncm) to ensure long-term stability and retrievability.

Clinical Benefits of Using Ti-Bases

• High strength and stability —the titanium core resists fracture and protects zirconia frameworks.
• Precision fit —machined tolerances within ±5 µm preserve preload and prevent screw loosening.
• Digital accuracy —validated for exocad®, 3Shape®, Dental Wings® libraries for perfect emergence and margin placement.
• Soft-tissue control —collar heights and concave profiles guide gingival healing and improve esthetics.
• Retrievability —screw-retained design allows future maintenance or crown replacement.

Choosing the Right Ti-Base

• Engaging (HEX) – for single crowns needing anti-rotation.
• Non-engaging – for bridges or multi-unit frameworks requiring a passive fit.
• Angled Screw Channel (ASC) – redirects the screw path 0°–30° for anterior esthetics.
• Gingival height (GH) – match to tissue thickness to support natural emergence.

Integrating Ti-Bases into the Workflow

1. Plan and place Internal Hex Implants with correct platform size.
2. Capture records with Scan Bodies or Digital Analogs.
3. Design and mill restorations in CAD software; bond them to the selected Ti-Base.
4. Seat and torque using Drivers & Torque Wrenches following IFU values.

Best Practices for Bonding and Maintenance

• Sandblast the bonding surface with 50 µm Al₂O₃ at 2 bar.
• Apply MDP primer and dual-cure resin cement approved for titanium–zirconia interfaces.
• Verify torque and document lot number for traceability.
• Replace prosthetic screws during any major servicing or remake.

Internal Hex Ti-Base CAD/CAM FAQs

How is a titanium base used in implant restoration?

A titanium base is attached to the implant to support a custom-milled crown or bridge. The restoration is bonded to the Ti-Base and torqued into place for long-term function.

Are Surcam Ti-Bases compatible with all Internal Hex implants?

Yes, Surcam Ti-Bases are designed for standard Internal Hex 2.42 / 2.43 mm connections and are compatible with major implant systems using that geometry.

Can I use Ti-Bases in both digital and traditional workflows?

Absolutely. Ti-Bases work with CAD/CAM systems for digital milling or can be used conventionally with impression analogs.

What torque should be applied when seating a Ti-Base restoration?

The recommended torque is 30 Ncm, unless specified otherwise in the IFU supplied with each component.

What advantages do Ti-Bases offer compared to full-zirconia abutments?

Ti-Bases provide superior mechanical strength, precision fit, and retrievability while maintaining esthetic outcomes, preventing ceramic fractures, and ensuring longevity.
