Apical Microsurgery - the 3rd Dimension

Short Abstract:

Apical microsurgery is a well-established treatment modality to preserve teeth with persistent or recurrent endodontic infection. In the last three decades, important diagnostic (three-dimensional radiography) and therapeutic inventions (surgical microscope, microtips for root-end cavity preparation, biocompatible root-end filling materials) have contributed to higher success rates of apical microsurgery compared to the traditional surgical technique. Yet, many cases are planned, treated and followed with two-dimensional (2D) imaging, i.e. periapical radiography or panoramic tomography. However, given the complexity of the surgical approach such as access, root- and canal morphology, as well as contiguous anatomical structures, three-dimensional (3D) imaging, i.e. CT or CBCT, has become an important tool to overcome these challenges.

By the end of this webinar the participant will be able to:
-Define the pre-, intra- and postoperative application of CBCT in apical microsurgery.
-Compare between the use of periapical radiograph and CBCT in apical microsurgery.
