S-Line shoulder abutment

Introduction

The Alfa Gate S-Line Shoulder Abutment is a precision-machined prosthetic component designed for cement-retained restorations on 3.0 mm S-Line implants. Fabricated from Grade 5 titanium alloy (Ti-6Al-4V ELI), it delivers optimal mechanical strength, precise marginal adaptation, and reliable prosthetic stability. The integrated shoulder geometry supports predictable crown seating and consistent margin positioning.

FAQ

Is this abutment compatible with NP or RP platforms?
No. It is engineered exclusively for S-Line 3.0 mm implants.

Why choose a shoulder abutment instead of a straight abutment?
Shoulder abutments provide a defined prosthetic finish line, improving margin control and crown seating accuracy.

What torque should be used?
Tighten to 20 Ncm with a 1.25 mm hex driver.
