Finite element analysis of a new alveolar bone splitting technique in the mandibular posterior region.

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
backgroundFinite element analysis was used to predict the risk of bone plate fracture and the expected bone augmentation effect of a new alveolar bone splitting technique in the mandibular posterior region for different alveolar crest widths, different alveolar bone densities, different root incision widths, and different insertion depths of bone expansion instrumentation.
methodsThe jaw models of the mandibular posterior region were constructed by computer-aided software and surgical incisions and bone expansion instruments were prepared on the models, after which the alveolar bone splitting procedure was simulated by finite element analysis software, and the equivalent stress-strain distribution characteristics of the jaw models of each group, as well as the maximal force and the maximal displacement of the bone plate when it was fractured, were recorded.
resultsThe distribution of equivalent stress and strain was mainly concentrated in the cancellous bone area at the root incision and the lower 1/3 of the buccal cortical bone plate, and there was no significant difference in the stress-strain distribution characteristics of the jaw models of each group. The wider of the alveolar crest, the higher the force required to fracture the bone plate, but the smaller the maximum displacement; the plastic deformation capacity of type IV bone jaws was more excellent; the wider the width of the root incision, the shallower the depth of instrument insertion, and the larger the maximum displacement.
conclusionFinite element analysis can effectively simulate the surgical criticality index of the new alveolar bone splitting procedure. Alveolar crest width, alveolar bone density, root incision width, and instrument insertion depth had a clear correlation with the maximum displacement of the bone plate at fracture. The alveolar crest width and alveolar bone density also had a significant effect on the maximum force required to fracture the bone plate.
