Short term dimensional bony changes following teeth extraction in the esthetic zone and the use of PRF as a sole grafting material: Randomized controlled trial

 
Background: Bone loss after teeth extraction is a repeated observation in dental practice. Many bio materials were used in
alveolar socket augmentation including platelet rich fibrin (PRF) to decrease bone loss.
Purpose: The aim of this study was to investigate the effect of PRF when used as a sole grafting material on the ordinary
dimensional bony changes following teeth extraction in the aesthetic zone.
Patients and Methods: 42 fresh extraction sockets in 27 patients were included in this study. Subjects were randomly allocated
into 3 groups. Study group included sockets augmented with PRF, second group included sockets augmented with xenograft
and the third negative control group included patients were extraction was done with no augmentation. Subjects were assessed
radiographically after extraction and before implant placement at 3 and 6 months post extraction using CBCT superimposition
to assess horizontal and vertical bone loss.
Results: The amounts of horizontal and vertical bone loss were significantly higher at 3 and 6 months in PRF group when
compared to xenograft group. PRF as a socket grafting has no additive effect on decreasing bone resorption in the short term
period after teeth extraction in the esthetic zone.
