Guest Editorial Microgap or Macrogap: Significance of the Marginal Discrepancy Between Implant Crown and Abutment
Frank R. LaMar, Jr, DDS
There has been an abundance of discussion about the “microgap” in implant dentistry, both in the literature and at scientific meetings. It appears to be accepted that the microgap between the top of the implant and the abutment is a space for bacteria to colonize and create an irritant that results in bone loss at the coronal aspect of implants. This bone loss has been referred to as “dive back” and appears to be acceptable to the first thread of the dental implant.
