Course Description: BM102

AGD Subject Code: 250

Closing midline diastemas with composite can be a challenge with achieving proper width, marginal staining, gingival emergence profiles and overhangs.  Matrix bands can produce long flat contacts and wedges may lead to unsightly black triangles. This live, step-by-by step interactive webinar focuses on Dr. Margeas’s simplified technique that quickly establishes ideal width, proximal contact and contour without removing any tooth structure and requiring minimal finishing.  Participants will also learn and perform polishing and surface texturing that will further produce predictably natural-looking long term restorations.

Who Should Attend This Course:

  • General Esthetic Dentists
  • RRDH (Dental Hygienists with a designation to perform Restorative procedures)

Course Outcomes & Hands-On Learning Objectives

  • Learn how to use the pull-through technique for tight diastema contacts;
