Management of Gingival Symmetry and Health Using the Er,Cr:YSGG Laser

The Er,Cr:YSGG Laser can be used in a variety of purposes and procedures by the clinician. In this podcast, the laser was used in three modes (gingival sculpting, osseous recontouring, and frenectomy). No tissue necrosis or significant bleeding occured as a result of the laser's relatively lower setting of 1.5 watts, 30% air, and 20% water.  Flowable composite resin was then placed along the mesiogingival aspects of teeth #8 and #9. Osseous sculpting required great precision in order to maintain a 3-mm dentogingival complex. The frenectomy was cleanly performed at the soft tissue setting (0.25 watts); biostimulation of the outer epithelium helped to decrease the release of histamine and increased fibroblasts for junctional epithelial growth.

*Private practice, Atlanta, GA

 

Learning Objectives:

Upon completion of this case study, the reader should:

  • Understand how the Er,Cr:YSGG Laser can be used in three distinct processes.
  • Understand the benefits of using the laser for these procedures.
