What technique is used for troughing soft tissue for a crown preparation with a surgical diode laser in contact mode?

In crown preparation using a surgical diode laser, the technique of employing light brush strokes is particularly effective for troughing soft tissue. This method involves gently moving the laser tip across the tissue, which provides precise control and minimizes damage to adjacent healthy tissues. The light brush strokes allow for the creation of a sulcular trough, essential for clear visibility of the tooth margins and facilitating accurate impressions for the crown.

Utilizing this technique is advantageous as it offers a combination of precision and minimal thermal damage to the soft tissue. This is critical in maintaining healthy tissue around the preparation site and aiding in the overall healing process post-procedure. The gentle approach of brushing with the laser minimizes discomfort for the patient and enhances the efficacy of the crown preparation by providing a clearer field of vision for the dentist.
