Abstract
PURPOSE: To compare dimensional changes and bone quality of two different grafting materials used for socket preservation. MATERIALS AND METHODS: Thirty-three patients requiring extraction were recruited and randomly assigned to receive: biphasic calcium sulfate/ hydroxyapatite (BCS/HA); bovine derived xenograft (BDX) or no grafting (Control). Ridge width (at -3 and -6 mm) and vertical distance from a stent were measured at the time of extraction/grafting. Measurements were repeated at reentry and core biopsies were harvested. RESULTS: Baseline vertical distance for the BDX, C and BCS/HA groups were 7.45 ± 3.1, 7.69 ± 4.2, and 6.75 ± 3.5 mm, respectively (P = .830). Post-op, C group had greater vertical loss (1.71 ± 0.4 mm) compared to BCS/HA (0.65 ± 0.5) and BDX (0.25 ± 0.2 mm), P = .059. Mean baseline width at -3 mm was 8.69 ± 1.1 mm, 8.31 ± 1.4 mm, and 9.0 ± 1.1 mm, respectively (P = .509). Post-op, this width was reduced by 2.96 ± 0.3 mm (C), 1.56 ± 0.4 mm (BDX), and 0.5 ± 0.4 mm (BCS/HA), P = .001. Mean ridge width at -6 mm for the C (6.5 ± 1.7 mm) was significantly smaller than BCS/HA (7.95 ± 2.8 mm) and BDX (8.85 ± 1.9 mm), P = .043. Histologically, the BDX group had greater residual scaffold material and less vital bone compared to the BCS/HA group. Pain scores were relatively low for all groups. CONCLUSIONS: BCS/HA may be used for socket preservation with similar or better results compared to BDX. The significance of greater residual scaffold found in the BDX group is yet to be determined.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
