The Effect of Vertical Implant Position in Relation to Interdental Crestal Bone Height of Adjacent Teeth on Implant Marginal Bone Loss: A Retrospective Radiographic StudyThe aim of the study was to investigate the effect of vertical implant position relative to the interdental bone of adjacent teeth on implant marginal bone loss. Electronic Health Records from 2011 to 2016 were screened for subjects with tooth bound single implants. Nobel Ti-Unite implants functionally loaded for over one year were included. The vertical distance from implant platform to interdental bone levels, relative to the adjacent tooth CEJ, and the marginal implant bone level were measured on the insertion and post- treatment radiographs. A total of 178 patients with 213 single implants were included. The overall implant survival rate was 99.1% over an average of 34.8 months follow-up. The mean vertical distance from implant platform to the interdental bone level was 1.28 ± 1.04 mm mesially and 0.83 ± 1.03 mm distally. The mesial platform was consistently deeper than the distal platform, with more bone loss at the mesial surface than the distal surface.
