Course Description

Zygomatic implants have proven results and have allowed us to treat the heretofore untreatable patient, to give hope to those who were told that there was none. Quad-zygoma formation is indicated in cases with inadequate bone density in maxillary zones 1-3. However, there are patients whose anatomy precludes the placement of 2 implants in one zygoma, or the previous failure has made repositioning a new implant impossible. An alternative site for anchorage should be explored to allow more “impossible” patients to return to function. Using accepted principles in full arch treatment, multicortical anchorage is possible using a “transnasal” approach. We will explore the history of using paranasal bone for dental implant placement and discuss the technique we use. 

Course Objectives

  • Review the basis of the trans-nasal implant
  • Review surgical anatomy
  • Review surgical technique
