What Are Locator Inserts?
Locator inserts — also referred to as locator caps — are the silicone retention elements used within the Locator® overdenture attachment system. They sit inside the metal housing embedded in the denture base and engage with the Locator® abutment on the implant, creating the retention force that holds the overdenture in place.
Replacing locator inserts is one of the most common chairside procedures in implant-retained overdenture maintenance — a simple, quick process that restores retention without replacing the entire attachment system.
Locator Inserts vs. Locator Caps — What's the Difference?
These two terms are often used interchangeably, but they refer to different components of the same system:
| Component | Also Known As | Function |
|---|---|---|
| Locator Insert | Locator cap, silicone insert, retention insert | The soft silicone element inside the housing that creates retention |
| Metal Housing | Cap, female component, overdenture cap | The metal ring embedded in the denture base that holds the insert |
Both components are available separately at DIP, allowing clinicians and laboratories to replace only what is needed:
- Overdenture Silicone Inserts / Caps — Zest® Locator Compatible
- Overdenture Attachment Metal Housing / Cap — Zest® Locator Compatible
For chairside insert replacement, DIP also carries the dedicated Rhein83 Insertion & Extraction Tool for Overdenture Silicone Caps — the professional tool designed specifically for safe, precise locator insert handling without damaging the housing or denture base.
European Quality — Manufactured by Rhein83
DIP's Zest® compatible locator inserts and caps are sourced from the same manufacturer as Rhein83 — one of Europe's most respected names in overdenture attachment systems. This means you receive:
- Identical manufacturing standards to the original European product
- Precise dimensional tolerances for consistent, reliable retention
- High-grade silicone engineered for long-term durability and patient comfort
- Full compatibility with Zest® Locator abutments and housings — zero compromise on fit
The result: European quality at a significantly more competitive price point than branded alternatives.

Locator Insert Color Guide — Choosing the Right Retention Level
Locator inserts are color-coded to allow quick chairside identification and easy retention customization. Here is a complete breakdown of each insert type:
| Color | Retention Level | Clinical Use |
|---|---|---|
| 🔵 Clear | Standard | The default starting point for most patients. Offers balanced retention suitable for the majority of overdenture cases |
| 🩷 Pink | Soft | For patients requiring lighter retention — ideal for those with limited dexterity, elderly patients, or cases with reduced implant angulation |
| 🟣 Purple | Hard / Strong | For cases requiring maximum retention — used when implants are well-aligned and the patient needs firm, secure hold |
| 🟡 Yellow | Extra Soft | The lightest retention available. Suitable for highly sensitive patients, initial insertion phase, or cases requiring minimal seating force |
| ⚫ Black | Lab Use Only | Not for clinical use — designed exclusively for laboratory processing and denture fabrication workflows |
| 🩷 Pink Flat (Thingy) | Protective Spacer | A flat protective insert used to protect the housing during processing or when the overdenture is not in use |
Clinical Tip
Start with Clear (Standard) for most patients and adjust based on patient feedback and dexterity. Moving to Pink (Soft) or Yellow (Extra Soft) is recommended for elderly patients or those with arthritis, as easier insertion and removal significantly improves compliance and long-term satisfaction.
When Should Locator Inserts Be Replaced?
Locator inserts are consumable components and will wear over time. Clinical guidelines generally recommend replacement when:
- The patient reports reduced retention or the denture feels loose
- Visible wear or deformation of the silicone insert is observed
- At routine maintenance visits, typically every 6–12 months depending on usage
Chairside replacement takes minutes and does not require laboratory involvement — making locator inserts one of the most practical maintenance solutions in implant prosthetics.
