Anatomy and Physiology of impression making for
the edentulous patient

Three learning objectives

  1. Identify and interpret the anatomical structures that physiologically limit the peripheral extensions for an impression of an edentulous area
  2. Determine the border movements that are appropriate to correctly activate these anatomical limiting structures
  3. Pros and cons of various impression materials and techniques for making impressions for the edentulous patient


Knowing and understanding the anatomical structures of the edentulous mouth is essential for making successful impressions.  Identifying the anatomical structures and understanding their function helps to determine what actions would best serve to physiologically form the peripheral extensions for the edentulous impression.  Each area of the arch will be academically ?dissected? and identified with updated terminology.  Individual variations of the anatomy will be noted and illustrated.  Since there are fundamental differences between the two arches the choice of impression materials and techniques may vary in order to maximize the stability and retention of the respective denture.  Special emphasis will be on a systematic technique for interpreting anatomical landmarks for outlining the extension of the mandibular custom tray.   Although this information is somewhat fundamental, it is my hope that the manner in which it is organized and presented will contribute to the efforts of educators who are responsible for sharing this information to students of dentistry.
