and then rinse with a light spray of water.
2. Air dry with low volume flow of air.
3. Lightly contact the sulcus lining just inside the crest of the
gingiva, angling the tip away from the tooth.
4. Using very light pressure, begin lasing as you make small
paint brush-like strokes tracing the area of the tooth that needs
to be exposed or where the restoration margins are not
completely visible.
5. If necessary to achieve desired results, increase power level
but always use the lowest amount of power necessary to reach
the treatment objectives and avoid charring tissue.
6. Create a small trough between the tooth and gingiva. This will
allow you to achieve a high quality optical image, scan
or impression.
7. You may also choose to recontour abnormal gingival tissue
to achieve better esthetics in a fraction of the time with greater
precision for outstanding results.
