Description:Endodontic Microsurgery may be a solution to remove an apical lesion and treat the endodontic cause of the infection, especially if the lesion is a cyst or if the retreatment too destructive for a good prognosis. According to a CBCT analysis, on lower molars the access must be difficult or very invasive with a thick mandibular bone (external oblique line) and on upper molars the sinus apical projection may make the access more complex. The “Cortical Bone Window” approach can be the minimally invasive solution. Thus, the visibility and the access of the lesion for the root preparation and filling would be more predictable. To be released, the quadrilateral piece of cortical bone can be cut with piezzo inserts in order to be more precise, less invasive and safe . The PRF preparations (clots and membranes) allow a better bone healing and an easier stable re-seating of the window. On molars endodontic surgery, the “Cortical Bone Window” technique may allow the operator an easier surgery and a quicker healing with a high regenerative healing potential.

    Analyze the indication of the "cortical bone window" technique on molars endo-surgery.
  • Describe the surgical approach of the "cortical bone window" technique
  • Describes the benefits of the "cortical bone window" technique when added to a PRF preparation.
