NiTi Brush™
the titanium brush for peri-implantitis

Shape-memory nickel-titanium bristles that reach into the implant threads and debride and polish the contaminated surface — on the 20:1 handpiece you already own.

Nickel-titanium alloy: contraindicated in patients who report a reaction to titanium or nickel (see the IFU).

Used as the reference decontamination step in randomised clinical trials (Monje et al. 2023; 2025) — 34 publications by 141 investigators at 59 institutions in 20 countries.

The reference step in clinical trials

When newer decontamination methods are tested, randomised trials often apply them on top of debridement with the NiTi Brush in both groups (Monje et al. 2025).

  • Named by the manufacturer in peer-reviewed papers — “a titanium brush (Hans Korea Co., Ltd.)”, “NiTi Brush Omega, Hans Korea”.
  • Used as the mechanical baseline in multicentre randomised trials — newer decontamination technologies are evaluated on top of debridement with this instrument.
  • Regulatory depth — CE Class IIa, MDR transition under way, established EU authorised representative.
  • Counted to a deliberately strict standard. The thirty-four publications on our Literature page are only those we have read in full, verified against the publisher's record, and in which the instrument is identifiable as the NiTi Brush from HANS Korea. Papers that report merely “a titanium brush” are not counted, even where we have reason to believe it was ours. The figure is therefore a floor; when a paper names the instrument, we add it.

The instrument at work 57 seconds, no sound

Surgical footage of debridement of the exposed threads with the NiTi Brush, followed by the CBCT record of the same site after combined surgical therapy with guided bone regeneration (the NiTi Brush was one step): bone loss around the implant before, new bone after.

Choose the instrument four models, one mechanism

Shape-memory Ni-Ti bristles bend into the thread rather than cutting across it — returning a contaminated implant surface to a machined finish while preserving the original geometry of the implant. Select by the access the defect allows. All models are driven by an implant motor with a 20:1 reduction handpiece at 600–1,200 rpm. New to the instrument? Start with what a titanium brush is.

What it does to the surface

Debrides and cleans the contaminated implant surface while preserving the implant threads. In a laboratory study on moderately rough surfaces (RBM, SLA), the bristles reduced micro-roughness by removing surface protrusions (Kim et al. 2016). Chairside, the endpoint is visible: the shade of the implant changes to a bright, machined finish.

The protocol example of protocol

  1. Diagnosis

    Diagnose peri-implantitis and measure the depth of the pocket.

  2. Select the brush

    NANO for 1–2 threads exposed · POCKET for more than 2 threads · POCKET SHORT for molars.

  3. Sterilise

    Supplied non-sterile. Autoclave in a pouch at 134 °C for 15 minutes.

  4. Rotate — debridement & decontamination

    Implant motor, 600–1,200 rpm with extensive external saline, until the contamination has been removed.

  5. Chemical treatment

    As reported in the literature: a tetracycline-HCl solution (e.g. 250 mg in 5 mL saline) on the debrided surface (Suh et al. 2003; Monje et al. 2026). The agent and protocol are a clinical decision — see the literature.

  6. GBR

    Guided bone regeneration follows the chemical step.

Use an implant motor — not a turbine or a straight handpiece

The NiTi Brush must be driven by an implant motor through a 20:1 reduction handpiece, run at 600–1,200 rpm with continuous external sterile saline. It is not intended for a high-speed turbine or for any drive that cannot hold this speed range.

Supplied non-sterile — autoclave at 134 °C for 15 minutes before every use. Single use only, do not reuse. This summary does not replace the Instructions for Use. Always read the IFU applicable to your market before treatment.

HANS Korea — the original instrument for peri-implantitis

HANS Korea has been developing the NiTi Brush since 2010 and filed its first patent for the instrument in November 2011. Every NiTi Brush since — NANO, POCKET, POCKET SHORT and OMEGA — descends from that original design.

It is a category we created and have refined for more than a decade, alongside the clinicians who use it.

About HANS Korea where the NiTi Brush came from

“In 2010, two ITI fellows and I sat in Osaka discussing peri-implantitis over sake until the early morning. That is the starting point of the NiTi Brush.”

HANS Kim Founder, HANS KOREA CO.,Ltd.
With Prof. Dr. Baek-Soo Lee (Department of Oral and Maxillofacial Surgery, Kyung-Hee University, Seoul) and Dr. Yasushi Nakajima, DDS, PhD, FITI (Osaka).

The original NiTi Brush™ — how to be sure you have it

HANS Korea developed the NiTi Brush and filed its first patent application for the instrument in November 2011. Similar devices exist. They are not made to our specification, they are not covered by our documentation, and their behaviour against a titanium surface has not been evaluated in the studies cited on this site.

Buy from HANS Korea or from an authorised distributor, and check that the product you receive is a genuine NiTi Brush™.

The clinical problem

Implants have been placed at scale for three decades. The population old enough to fail grows every year, and peri-implantitis is the reason most of them do.

~1 in 5 of implant patients affected (21%) — about 1 in 8 implants — in the latest meta-analyses1,2
≤ 3 yrs from loading to the onset of bone loss in most cases3
Surgical established lesions generally require flap access to decontaminate the surface

And removing the implant is often not an option

A single, standalone implant in a healthy patient can usually be explanted and replaced. That changes when the patient is older and carries comorbidities, or when the case rests on several implants — where even one failing implant cannot be dealt with in isolation, and a fixed bridge would have to be dismantled to reach it. In those cases the realistic path is to decontaminate the surface and keep the implant in function. Read more →
