Indications / Advantages

KEXIM is an explantation system designed to remove osseointegrated implants using a controlled countertorque technique, minimising trauma to the implant site and promoting its preservation for subsequent restoration.

Advantages of using KEXIM

Universality and versatility

Its extensive range of extractors, with different geometries, enables the removal of implants from different systems and with different connection types, in cases of both biological and mechanical complications.

Minimal invasiveness and bone preservation

Using a countertorque wrench limited to 200 Ncm, KEXIM enables the bone–implant bond to be broken and the implant to be explanted while maximally preserving the surrounding bone tissue. This conservative approach can prevent or reduce the need for trephine burs and facilitate immediate placement of a new implant when clinically indicated.

High clinical predictability

The efficacy of the system is supported by clinical studies documenting a 98.4% success rate in the explantation of 749 osseointegrated implants. These findings demonstrate the predictability of the countertorque technique as a conservative alternative for implant retreatment. (1)

Solutions for complex cases

If explantation requires more than 200 Ncm, the system is complemented by ultra-thin cutting trephine burs (KFTEX-8 kit). Trephination of only 2–5 mm reduces the maximum torque required by more than half, ensuring successful removal with minimal bone trauma. The kit also includes extractors specifically designed for cases in which the fractured screw remains lodged within the implant.

Counter-torque wrench

The kit includes the LLT200 extraction wrench, an essential instrument that allows the bone–implant union to be disrupted easily by applying controlled force up to a limit of 200 Ncm.

Single-use extractors

It includes a wide range of extractors for both internal and external connections (such as EXIM, EXIMA and INEXIM, among others), with different diameters and lengths to enable precise adaptation to the various implants available on the market. In addition, it includes specific references (EXIM5, EXIM6 and EXIM7) expressly designed for the removal of implants in which the fractured screw has remained lodged inside

Preparation burs

It incorporates burs (such as the DRL-E and DRL-25) designed to prepare the base of the implant connection. In cases where implant anatomy requires it, this preliminary step facilitates improved extractor retention in the most robust area of the implant.

Extenders

The system includes a set of wrench extenders (ELLCAC, ELLCAL and ELLCAX, corresponding to short, long and extra-long sizes). These components ensure optimal reach and improve clinical manoeuvrability in any area of the oral cavity.

Advantages of the KEXIM implant extraction kit

Ventajas del sistema CORE-X

  • Optimised components

    The kit includes a precise counter-torque wrench (up to 200 Ncm), single-use extractors adaptable to different implants, burs for connection preparation, and a carrier handle (MDPT), providing everything required for safe explantation.

  • Clinical efficiency

    It significantly reduces surgical time and increases the predictability of re-treatment.

  • Tissue preservation

    Its atraumatic approach is critical for maintaining bone architecture, thereby supporting subsequent rehabilitation options.

  • Maximum gripping capacity

    The single-use nature of the extractors ensures that the frictional properties and geometry of each component are intact in every procedure. This prevents any failure due to material wear and ensures that torque is transmitted to the implant with maximum effectiveness.

  • Ergonomics and accessibility

    The incorporation of dedicated extenders for the counter-torque wrench greatly facilitates clinical manoeuvrability. This allows the required force to be applied comfortably, precisely and safely, even in posterior sectors or in the most difficult-to-access areas of the oral cavity.

Frequently asked questions from the experts

Is the KEXIM kit compatible with other implant brands on the market?

KEXIM is designed to work with both internal- and external-connection implants. The extraction kit is currently universal and compatible with more than 35 different implant systems.

Can an immediate implant be placed after extraction with KEXIM?

Yes, provided that the clinical conditions allow it. The KEXIM® countertorque technique promotes peri-implant bone preservation, facilitating the immediate placement of a new implant. However, the case must be reassessed, taking into account the cause of the previous implant failure, the presence of infection, the volume and quality of the residual bone, and the possibility of achieving adequate primary stability. When these factors are favourable, immediate implant placement can reduce treatment time and avoid a second surgical intervention.

What happens if extraction requires more than 200 Ncm of force?

If osseointegration is severe and exceeds 200 Ncm, the system can be supplemented with ultra-thin cutting trephine burs. Superficial trephination of only 2–5 mm reduces the maximum torque required by more than half, ensuring successful explantation without damaging the bone architecture.

Is it possible to remove an implant if there is a fractured screw inside it?

Yes. The kit addresses complications of mechanical origin specifically. It includes extractors expressly designed for the removal of implants in which the fractured screw has remained lodged inside, allowing the situation to be resolved without additional complications.

Are the extractors inserted into the implant reusable?

No. The extractors included in the kit are single-use. Because they are discarded after each procedure, the geometry of the component is protected from wear and its frictional capacity to transmit counter-torque force is maintained intact in a predictable and safe manner.
