S-12 An Innovative Approach to Endodontic Microsurgery Utilizing 3-D Printed Guides and Trephine Burs

4.5 (2 votes)

CE Hours: 1.5

Course Description:

Surgical guides play a prominent role in implant placement, but do not have widespread use in endodontic microsurgery (EMS). A limited number of articles document applications of guides in EMS. Entry level 3-D printers with resin cost around $1,000. CBCT files can be imported into planning software, allowing 3-D printing of surgical guides. Trephine burs have been used for autogenous bone graft harvesting and for removal of failed implants, but have not previously been used in EMS. Here, we present an innovative technique pioneered at the Air Force Post-graduate Dental School which uses CBCT, software-designed 3-D guides, and trephine burs to define perforation site, angulation, depth and diameter to achieve osteotomy, root end resection and biopsy in a single step. The presentation includes cases in which surgical guides allowed teeth to be saved in anatomically complex scenarios, such as in a palatal approach for a maxillary 2nd molar. 

At the conclusion, participants should be able to:

  • Identify the general steps in utilizing CBCT, planning software, and 3-D printing to fabricate endodontic microsurgical guides.
  • Describe characteristics and functionality of autogenous bone harvesting trephine burs in endodontic microsurgery.
  • Describe the combination of 3-D printed guides and trephine burs in endodontic microsurgery, particularly in anatomically complex areas.
