IBO ACS 4-Lobed prosthetic component, reference IBO 1501 225, M1.8 ACS 4 Lobed Screw 1501 225. The 4-Lobed drive interface provides enhanced rotational torque transfer and reduced cam-out compared to traditional hex drives in the prosthetic Screw application.

Used in IBO's ACS-compatible prosthetic workflows to fixate abutments to implant fixtures with controlled, repeatable torque. The 4-Lobed drive accepts the matched IBO ACS driver tip and reduces driver slippage during final torque application.

The ACS 4-Lobed interface is used across IBO's Conical Reactive and INTHEX (Internal Hex) prosthetic lines where ACS-compatible screws are specified. Refer to the IBO instrument kit for the matched driver reference.

Machined from medical-grade Ti-6Al-4V ELI Titanium (Grade 5), ASTM F136 / ISO 5832-3, selected for biocompatibility, mechanical strength and chemical stability in the oral environment.

All materials and processes comply with current regulations and are subject to full traceability from raw material to final validation.

Supplied in the manufacturer's validated condition for clinical use. Follow the package insert and IBO Instructions for Use for handling, storage and any chairside preparation steps. Do not modify the geometry or surface in any way; doing so compromises both clinical fit and regulatory clearance.

Single-use device. Single patient, single procedure. Discard unused components per local biohazard regulations.

IBO operates under ISO 13485:2016 quality management for the manufacturing of medical devices, holds the AEMPS Spanish Agency of Medicines and Medical Devices licence, and every IBO component carries the CE marking MDR, assessed by a Notified Body.
