Dr. Gerald Niznick


Evolution of Implant Prosthodontics

Course Title:

The Evolution of Implant Dentistry

Course Description:
This presentation will cover the evolution of both implant and abutment hardware over the last 40 years as well as the development t of prosthetic treatment protocols. The first documented case with an over denture attached to two free-standing implants was in 1982 (Niznick AAID Journal) and today it is considered as the minimum standard of care for treating the edentulous lower jaw. Implant designs and surfaces have evolved from requiring 3 months of submerged healing to immediate load of single tooth replacement. Implant prosthetics has vacillated between screw-retained and cement retained restorations. Implant design options evolved from one-piece to two-piece and back to application specific one-piece implants, from straight to tapered implant bodies, from external hex to internal hex connections, from butt-joint to conical connections and from non-sterile packaging to sterile All-in-1 packaging. The implant industry has grown from a handful of companies in early 1980’s to over 250 implant companies each trying to capture market share by touting their product’s unique selling proposition, whether it be a new and improved surface, aggressive thread design, tapered or straight body shape, implant/abutment connection designs. Public awareness of implant treatment has evolved from a few members of AAID identifying themselves as implantologists in the 1970’s to the $6B per year global implant market that it is today.

Learning objectives for this lecture:

  • Trace the search for the ideal implant
  • Know to differentiate between clinical reality and marketing rhetoric when it comes to implant selection
  • Immediate load vs non-submerged vs submerged healing
  • Explore the treatment options being advocated for restoration of totally edentulous jaws
