Marginal Bone Loss
Evaluation of Marginal Bone Loss (MBL) 12 Months Post-loading of Implants Supporting Individual Crowns, Based on the Height of the Intermediate Abutment and Its Placement Time. Immediate Abutments of 2 or 3 Mm Show the Lowest MBL, Whereas 1.5 Mm or Delayed Abutments Are Associated with Higher MBL.
Objectives:To determine which combination of abutment height and timing of placement is most effective in reducing marginal bone loss (MBL).
