Hands-on Session with Dr Maarten de Beer

 

Deep Margin Elevation & Rubber Dam Isolation

Dr. Marteen de Beer is leading a workshop titled ‘Improve Margin, Improve Success!’ This interactive session introduces the M-I-M method (Matrix in matrix) for addressing deep subgingival margins in an efficient way. The workshop will teach you how to reposition difficult margins to a higher level, boost isolation and bonding, and achieve consistent restorative outcomes.

Participants will engage in hands-on exercises, working on margin correction, matrix alignment, handling materials, and refining restorations.

Be sure to join Dr. de Beer to enhance your techniques and take your restorative process further. Looking forward to seeing you at the Kerr Summit!
