Abstract:
A retrospective case series was used to evaluate the effect of plasmatrix bone blocks on bone augmentation at the level of the alveolar ridge. From January 2021 to April 2022, a total of 25 patients who underwent horizontal alveolar ridge level bone augmentation in the Department of Implantology, Wuhan Dazhong Stomatological Hospital were included. Autologous bone chips, deproteinized bovine bone matrix and plasma matrix were used to make plasma matrix bone blocks, combined with absorbable collagen membrane and plasma matrix membrane for guided bone regeneration. Three-dimensional reconstruction was performed on the cone beam CT data before operation and 6 months after operation, and the bone width and alveolar bone volume at 2 and 8 mm from the alveolar crest were measured. The paired t test was used to compare the differences between two time points of the same measurement item. The results showed that compared with preoperative [(5.5±3.4) mm] bone width, the bone width [(9.5±2.5) mm] at 2 mm from the alveolar crest was significantly increased at 6 months after operation ( t=3.40, P?0.001); there was no significant difference in the bone width at the level of 8 mm from the alveolar crest between pre-and 6 months post-operation ( t=3.13, P=0.050). The volumes of alveolar bone at 2 and 8 mm from the alveolar crest were (5 114±3 883) and (3 329±2 874) mm 3 before operation, respectively, and these increased significantly to (5 999±4 318) and (4 042±3 260) mm 3 ( t=5.69, P?0.001; t=5.689, P?0.001) 6 month post-operation. The results from this study has shown that the use of plasmatrix bone blocks+absorbable collagen membrane+plasma matrix membrane for horizontal bone augmentation in guided bone regeneration has a promising bone augmentation outcome.
