Dental Feature: Laser Crown Lengthening


Breed: Belgian Malinois

Complicated Fracture of the
Left Maxillary Canine

The patient's left maxillary canine was fractured with pulp exposure (a complicated crown fracture). But dental radiographs revealed that the root was still intact and savable.


The pulp chamber was first cleaned and then filled with gutta percha. Standard root therapy was performed.

Next, the crown lengthening procedure was performed. A diode laser was used to do a laser gingivectomy and expose more of the tooth's surface. A pin was placed in the pulp chamber and core build-up material was used to build up the crown.

After crown prep

Diode lasers operate at about 810 nanometers. This is a safe level for working around hard tissue such as the alveolar bone and the periodontal ligaments in the oral cavity.

Two weeks after crown cementation

The patient recovered extremely well from the surgery and, five years later, is still doing great.
