Managing Complex Endodontic Microsurgery: From the Piezotome and PRF to Intentional Replantation

Product not yet rated

CE Hours: 2.0

Description: Use of the Piezotome for endodontic microsurgery has become quite popular, especially creating a bone "window" or "lid" to gain better access to areas like mandibular molars with thick cortical bone. It can be technique sensitive to replace those windows securely, allowing for the bone to revascularize and maintain the osteotomy space. This lecture will discuss drawing the patient's blood and centrifuging out platelet-rich fibrin plugs and membranes as well as crushing the bone "window" and mixing it with the serum created from forming the PRF membrane to make "sticky bone", which is sandwiched in between the PRF plugs and covered by the PRF membrane.
The latter part of the presentation will focus on treatment planning and case selection for Intentional Replantation, explaining the techniques in detail and showing several clinical cases with follow ups.

Learning Objectives: 

  • Describe when a piezotome should be incorporated for creating a bone window (boney lid) during endo microsurgery
  • Describe alternative treatment utilizing Platelet-Rich Fibrin (PRF) derived from the patient's own blood and creation of autologous sticky bone
  • Describe Intentional Replantation and be comfortable performing in their private clinics
