Straight Curve Wide Platform - Concave

Wide 4.5 straight concave abutment for soft-tissue sculpting, cleansable emergence & posterior stability (GH 1–4 mm)

The Surcam Straight Curve Wide Platform – Concave is a straight, concave transmucosal abutment engineered for Wide Platform 4.5 implants. Precision-machined from Titanium Grade 5 (Ti-6Al-4V), its concave collar supports natural soft-tissue architecture and a hygienic emergence profile while providing a stable base for posterior function. Available in gingival heights 1.0 / 2.0 / 3.0 / 4.0 mm, it streamlines delivery of cement-retained single crowns and short-span bridges.
Includes: 1× Straight Curve Concave Wide Abutment, 1× Prosthetic Screw.
Compatibility: Wide Platform 4.5 families (commonly Internal Hex 2.42 interface). Brands include Alpha Bio®, Zimmer®, MIS®, Adin®, Implant Direct®, AB Dental® — verify interface/fit prior to use.

Concave Wide Abutments FAQs

Which implant platforms are compatible?

Wide 4.5 platform implants used by systems such as Alpha Bio®, Zimmer®, MIS®, Adin®, Implant Direct®, AB Dental®; commonly Internal Hex 2.42. Always verify the platform and interface before use.

How do I select the gingival height?

Match GH to soft-tissue thickness and desired emergence: thin tissue → 1.0 mm; average → 2.0 mm; thicker biotype/convex emergence → 3.0–4.0 mm. Confirm clinically and radiographically.

Is this abutment for cement-retained or screw-retained crowns?

Primarily cement-retained. The included screw secures the abutment to the implant; follow your system’s cementation protocol for the crown.

Does the concave collar help hygiene?

Yes. The concave transmucosal profile reduces subgingival bulk and supports cleansable contours when combined with proper margin design and maintenance.

What torque should I apply?

Use the manufacturer-specified torque for Wide 4.5 (IH 2.42) abutments per the implant system IFU. Do not exceed recommended values.

Can I use this in posterior load cases?

Yes, Wide 4.5 provides a broader base suitable for posterior function when prosthetic design and occlusion are properly managed.
