1 · What the graph read from it

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.

2 · The registry

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

Micromotion between IAI affects long-term survival rate of dental implants. The use of practical implants for mechanical test is costly. Finite element analysis (FEA) could test the micron level deformation changes, but whether it reflects the in vitro mechanical performances remains unknown. This study aims to investigate the correlation between IAI micromotion of FEA and in vitro performances. The two-step-two-component FEA method was used to test the relative deformation between IAI for three implant designs (M1, M2, and M3) during torque loading and cyclic oblique loading. The micromotion was divided into directions that perpendicular to (x-axis) and parallel to (y-axis) IAI. In vitro experiments on the micromotion relevant performance of IAI microleakage (tested by toluidine blue releasing with a spectrometer) and IAI locked condition (tested by abutment removal force tests after detaching the central screws) were also conducted for the identical implant systems (G1, G2, and G3). One-way ANOVA and Pearson's correlation tests were performed for data analysis. FEA illustrated that the three implant systems performed different micromotion patterns. Significant differences were found in the IAI microleakage and removal force among the groups. Positive correlations were found between FEA and in vitro outcomes. Therefore, the two-step-two-component FEA method is an appropriate method to evaluate the IAI micromotion after loading. Graphical abstract The correspondence of IAI micromotion between FEA analysis and in vitro performances.
