RADIOGRAPHIC ASSESSMENT OF PERI-IMPLANT VERTICAL BONE LOSS - DICRG INTERIM-REPORT NO. 9

Vertical bone loss is being assessed radiographically as part of the D ental Implant Clinical Research Group studies through direct measureme nts on study radiographs taken longitudinally at surgery and recall ap pointments. Preliminary results and trends for the period between impl ant placement and 6 months after implant uncovering show more bone los s in implants that are 1) not coated with hydroxyapatite; 2) placed in the maxilla; 3) placed in anterior regions of the jaws; 4) in complet ely edentulous cases; and 5) placed in bone scored as having lower qua lity, Confounding relationships between predictor variables will requi re controlled statistical analyses when data collection is completed.
