Pterygomaxillary Dental Implants


The Importance Of Zygomatic And Pterygomaxillary Implants In Prosthodontic Treatment

Lecture Presented At:

AMERICAN COLLEGE OF PROSTHODONTICS MEETING IN BALTIMORE

November 2-4, 2012

AMERICAN ACADEMY OF FIXED PROSTHODONTICS Meeting Chicago

February 23, 2013

Dr. Balshi was invited to present the Pi research and evidenced based treatment protocols related to this implant method to the ACP and the AAFP as noted above.

Objectives of Presentation

  •    Define zygomatic and pterygomaxillary implants?
  •    Why use these locations for implants?
  •    Do they work? Evidence-based prosthodontics
