Komet’s new amalgam remover H4A: Less mercury vapor. More safety.
Published on
Lemgo, January 5, 2026 – The H4A, Komet’s new amalgam remover, makes the removal of amalgam safe, simple, and efficient. The H4A, Komet’s new amalgam remover, makes the removal of amalgam safe, simple, and efficient. Whether due to age, damage, caries, or for cosmetic reasons—the removal of amalgam fillings is a routine procedure at any dental practice.
In addition to performing a successful restoration while preserving as much of the natural tooth as possible, protecting the patient and the dental team from potentially toxic mercury vapors is an absolute priority when it comes to removing amalgam fillings.
While amalgam could already be removed quickly and safely using Komet’s previous amalgam remover, the H32, Komet is now introducing its successor, the H4A, which makes treatments particularly safe, simple, and efficient for users: Developed specifically in Lemgo for this application, this instrument significantly reduces mercury vapor emissions by 40%* compared to its predecessor.
H4A – Sharper equals faster equals safer.
With the H4A amalgam remover, the Lemgo-based dental specialist is not only introducing a successor to the tried-and-true H32. The new and improved amalgam remover from Komet enhances user safety by reducing the risk of mercury vapor formation by more than a third*.
The new amalgam remover owes its significantly higher efficiency to the greater sharpness and optimized geometry of its blades: the new tooth design allows for easy, precise penetration into the filling material and a high rate of material removal, while demonstrably reducing the formation of mercury vapor.
Shorter treatment times and a gentle procedure for amalgam removal.
The new amalgam remover, featuring Komet's renowned and proven quality, can significantly reduce treatment times thanks to its ability to remove old fillings very quickly. The difference may seem small when looking at each individual treatment, but the time saved adds up to a financially significant difference at the end of many a day in the dental practice.
The sharp blade offers another advantage for patients: the remaining natural tooth structure can be optimally protected thanks to its exceptional sharpness, which ensures precision. All in all, Komet’s H4A is a state-of-the-art amalgam remover that further enhances an already excellent instrument thanks to its new and improved geometry.
