ABSTRACT
The aim of this randomised controlled clinical trial was to assess the early efficacy of bone morphogenetic protein-2 with hydroxyapatite granules (BMP-2/hydroxyapatite) on augmentation of the alveolar ridge, by comparing changes in volume with those associated with the use of an inorganic bovine-derived xenograft (BDX). We studied 20 patients who were divided into two groups using a table of random numbers, and BMP-2/hydroxyapatite and BDX were applied accordingly. Computed tomographic (CT) images and panoramic radiographs were obtained immediately after operation and four months later. CT images were reconstructed in three dimensions to measure volumetric changes, and linear measurements were made on panoramic images. The mean (SD) absorption rates for BMP-2/hydroxyapatite and BDX were 13.2 (8.8)% and 13.8 (20.5)%, respectively. While the mean value did not differ significantly between the two materials, the SD was higher in the BDX group than in the BMP-2/hydroxyapatite group. No clinically important complications occurred in either group. We conclude that both BMP-2/hydroxyapatite and BDX were effective in augmenting the alveolar ridge, but BMP-2/hydroxyapatite seemed to be more useful in complicated bone defects.
