Abstract
  • Objectives: Characterize dimensional changes of the alveolus and soft tissues 3 months following post extraction ridge preservation with different grafting materials. Methods: 80 patients were recruited. Post-extraction sockets were randomly treated with Allograft, Alloplast, or Xenograft bone graft with membrane coverage, or ungrafted control with membrane alone. CBCT imaging and impressions were taken at baseline and 3 months post extraction. Dimensional changes were evaluated using 3D Slicer. Implant planning using coDiagnostiXTM was used to evaluate the need for additional bone augmentation. Results: 12 patients provided pilot data. No differences in volumetric or linear dimensional changes were seen between treatment groups, but trend for improved hard and sot tissue maintenance were suggested compared to the control group. Buccal plate thickness was inversely related to bone loss when not grafted. Ideal implant positioning in treatment groups is achieved, with the control group often requiring further bone grafting. Conclusions: Ridge preservation procedures may reduce the amount of bone loss and reduce the need for additional bone grafting prior to implant surgery.
