Effects of concentrated growth factor combined with Bio-Oss bone powder on guided bone regeneration in the maxillary posterior region.
Article in American journal of translational research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo evaluate the clinical effects of concentrated growth factor (CGF) combined with Bio-Oss bone powder on guided bone regeneration for the maxillary posterior region.
methodsThis retrospective study included 32 patients with missing maxillary posterior teeth and severe alveolar ridge atrophy requiring implant restoration for retrospective analysis. Sixteen patients received CGF combined with Bio-Oss treatment (CGF/Bio group), while the remaining 16 received Bio-Oss treatment only (Bio group). The Bio group used Bio-Oss bone powder directly. Cone-beam computed tomography (CBCT) was performed preoperatively and at 2, 4, and 6 months postoperatively to evaluate bone mineral density (HU values). The implant retention rate, soft tissue healing time, postoperative pain, and swelling were also evaluated.
resultsThe 1-year implant retention rate was 100% in the CGF/Bio group and 81.25% in the Bio group (P = 0.054). Soft tissue healing time was significantly shorter in the CGF/Bio group (P = 0.122). Bone density was significantly higher in the CGF/Bio group at 2, 4, and 6 months postoperatively (P < 0.05). Postoperative pain and swelling were significantly lower in the CGF/Bio group (P = 0.008 and P = 0.014, respectively).
conclusionThe combined application of CGF and Bio-Oss bone powder in maxillary sinus external lift demonstrates superior clinical outcomes, offering improved bone augmentation and enhanced postoperative healing compared to Bio-Oss bone powder alone.
