Workshop on lasers in implant dentistry, in Milan

At the invitation of MegaGen, Prof. Ana Catarina Nogueira da Silva took part in the European Scientific Meeting 2026 in Milan, where she co-led, with Prof. Rami Ghali, a workshop on the applications of lasers in implant dentistry.

The meeting was an opportunity to share knowledge, engage in scientific discussion and showcase the potential of laser technology in clinical practice.

Her participation reinforces her commitment to continuing education and to promoting evidence-based dentistry.

Thanks go to MegaGen for the invitation, the warm welcome and the excellent organisation of the event.

For patients

What you need to know.

Advantages, myths, safety and the questions most often asked in clinic.

For dentists

Clinical reasoning before technology.

Parameters, protocols, choosing equipment and integrating lasers into clinical practice.

  • In Portuguese

    The first thing I teach about lasers

    Clinical reasoning always starts with the diagnosis and the biological goal of treatment. Only then are the laser and parameters chosen.

    The most common mistake when using a laser

    It isn’t a lack of equipment — it’s a lack of protocol: diagnosis, tissue type, chromophore, biological goal and emission mode.

    Is power the most important parameter?

    The effect of a laser comes from a combination of factors and from how energy is delivered to the tissue.

    Starting with the equipment. First come the clinical indications, the treatment goals and how it will fit into practice.
