3D Printing Guides for Targeted Endodontic Microsurgery (TEMS)

CE Hours: 1.75 CE hour 

Description: Targeted Endodontic Microsurgery (TEMS) utilizes trephine burs and 3D-printed surgical guides to achieve osteotomy, root resection and biopsy in a single step. The digital workflow for guide production is marked by conversion of a patient’s physical anatomy into digital data that forms a digital model upon which a TEMS guide is designed and then 3D-printed. This presentation aims to demystify the digital workflow and guide design process, and to show proper clinical applications of the surgical guide. Participants will see several methods for digitally rendering bone, teeth, neuro-vascular structures, crowns and soft tissues. Principles of digital model creation within design software will be presented so that clinicians can communicate meaningfully with a 3D printing lab. Finally, several TEMS cases with treatment planning considerations will be presented including palatal roots of maxillary 1st and 2nd molars and mesial and distal roots of mandibular 1st and 2nd molars.

At the conclusion, participants should be able to:

  • Describe different ways of digitizing hard and soft tissues for creation of a digital model.
  • Describe surgical guide design principles for communication with a 3D printing lab.
  • Describe all clinical phases of guided surgical endodontics to include presurgical evaluation, radiographic evaluation, treatment planning and intraoperative application.
