Effect of platelet-rich plasma in alveolar distraction osteogenesis: a controlled clinical trial.

We have evaluated the effect of the use of platelet-rich plasma in alveolar distraction osteogenesis. Fourteen patients who were partly edentulous in the anterior premaxilla region were selected and randomised into two groups (n=7 in each group). Those in the experimental group were give platelet-rich plasma at the time of distraction, and the control group had only distraction. Selected cases had defects in the alveolar ridge of more than 3mm, and a minimal bone height of 7 mm from the alveolar ridge crest to important anatomical structures. The plaque index and gingival index were recorded on days 3, 7, 14, 21, 28, 45, 60, 75, 90, and 105 postoperatively. There was a strong negative correlation between the gingival index and augmentation of bone, and a strong positive correlation between the mean gingival index and loss of bone from the transported segment. The addition of platelet-rich plasma had a protective effect on the mucosa around the distractor, which decreased the potential for complications.
