Evaluation of graft osteogenesis using fractal dimension analysis on cone-beam computed tomography images following maxillary sinus lift surgery.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundFractal dimension (FD) analysis is a method used to numerically characterize the complexity of structures or tissues. After sinus lift procedures, the graft material gradually transforms into natural bone over time. This study aimed to evaluate the interpretability of this transformation by assessing changes in FD values.
methodsIn this retrospective study, data from a total of 36 patients (42 hemimaxillae), including 13 females (17 hemimaxillae) and 23 males (25 hemimaxillae), were analyzed. Cone-beam computed tomography (CBCT) images obtained preoperatively and at six months postoperatively from patients who underwent sinus lift surgery with graft placement in the maxillary molar region were included in the evaluation. The pre- and postoperative images were superimposed using anatomical reference points. Examination areas were determined on cross-sectional slices from the grafted and adjacent non-grafted bone areas (used as control) within the maxillary molar region. FD analysis was performed on these areas. FD values from the grafted and control bone regions at baseline and six months were recorded. Paired and independent sample t-tests were used for statistical analysis, with statistical significance set at p < 0.05.
resultsFD values derived from CBCT images showed a statistically significant difference between the initial state of the graft immediately after placement (G0) and its state six months postoperatively (G1) (p < 0.05). The mean FD values were 1.297 for G0 and 1.279 for G1. However, no significant difference was observed between the initial state (B0) and the six-month follow-up state (B1) of the trabecular bone in the posterior region used as a control (p > 0.05). The FD values in the G0 group showed minimal variation across gender and age groups, consistently ranging between 1.295 and 1.299. No significant differences in FD values were identified based on gender or age groups (p > 0.05).
conclusionsThe findings of this study suggest that FD analysis may serve as a useful adjunctive tool for evaluating graft osteogenesis.
