IBO manufactures the Soft Red silicone Retention insert for the LOCK-ATTACH overdenture attachment system. The Soft Red insert provides a light Retention (extended) Retention level: low Retention force with extended-life silicone formulation, typically used for transitional cases or specific anatomical considerations.

The Retention insert sits inside the LOCK-ATTACH Titanium Female Housing (HE-41918) embedded in the overdenture base and engages the male LOCK-ATTACH Abutment screwed onto the implant. Insert colour is the only way to identify Retention class chairside.

The Soft Red insert is selected when the prosthodontist requires light Retention (extended) Retention — either to compensate for limited manual dexterity in the patient, to stage Retention over the rehabilitation timeline, or to balance Retention across multiple LOCK-ATTACH abutments in the same arch.

A common protocol is to start a new overdenture with a lower Retention class while the patient learns to seat and remove the prosthesis, then step up to higher Retention as the patient adapts.

This Retention insert is a wear component within the IBO LOCK-ATTACH overdenture attachment system. It is compatible across all LOCK-ATTACH platforms (Internal Hex, Conical Reactive, Multiunit) since the female housing is platform-agnostic.

IBO LOCK-ATTACH Retention inserts are manufactured from medical-grade silicone formulations validated for intra-oral use. Each Retention class is colour-coded for fast chairside identification.

The silicone formulation provides controlled, repeatable Retention force across the service life of the insert and is designed for periodic replacement as part of routine overdenture maintenance.

All materials and processes are subject to full traceability from raw material to final validation.

IBO LOCK-ATTACH components are supplied in the manufacturer's validated condition for clinical use. Follow the package insert and IBO Instructions for Use for handling, storage and torque protocol. Do not modify the component geometry or surface in any way; doing so compromises the prosthetic interface and the regulatory clearance.
