Surgical implant placement guides/ dentistry dental implants

  1. 1. A surgical guide for dental implant placement in edentulous posterior regions INDIAN DENTAL ACADEMY Leader in continuing dental education
  2. 2. Introduction: The accurate placement of the implant is critical to achieving a pleasing esthetic result, as well as the correct alignment for withstanding occlusal forces. It is well documented that dental implants placed using a surgical guide are more accurately positioned than those placed without a guide.
  3. 3. An implant placement guide also allows for less stressful surgery for the operator, knowing that the critical placement factors were considered in the fabrication of the guide. It then becomes a matter of exposing and preparing the osteotomy site and placing the implant. A stable and accurate surgical guide provides a precise reference for implant placement.
