Metal welding with pulsed Nd:YAG laser in the oral cavity was done in three clinical cases. The laser irradiation was performed with the parameters 9 W, 10 pps, and 900 mJ/pulse, with a 600-µm-diameter laser tip and air spray cooling in noncontact mode. In the first case, metal was laser welded to fix anterior teeth covered with metal-porcelain crowns. The second case involved welding a metal crown to a metal bridge. In the third case, welding was used to repair an orthodontic bracket. In these 3 cases, metal welding with Nd:YAG laser in the oral cavity was successful, even at the one-year follow-up.
