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

backgroundThe dimensional accuracy and fit of zirconia implant-supported crowns fabricated using material jetting (MJ) technology remain unclear, particularly at critical intaglio interfaces. This study compared the accuracy of a modified implant-supported crown fabricated by MJ and subtractive manufacturing (SM).

methodsA modified implant-supported crown structure was designed and fabricated using MJ (Carmel 1400 C, Xjet) and SM techniques (n = 12 crowns and 12 inlays per group). Three intaglio regions were analyzed: the inlay intaglio surface (IIS), crown–inlay contact surface (CIS), and crown–abutment contact surface (CAS). Specimens were scanned, aligned to CAD references via best-fit in 3D inspection software, and assessed for trueness and precision. Trueness was analyzed using independent t-tests (α = 0.05), and intraclass correlation coefficient (ICC) was used to assess the agreement of precision.

resultsMJ exhibited significantly higher trueness than SM in all regions (p < 0.05), with the largest difference observed in the CIS region. All MJ samples remained within the clinical threshold (< 120 μm), while SM exceeded it in CIS (203.08 μm). ICC analysis showed low agreement in precision between MJ and SM. SM restorations exhibited seating interference, whereas MJ restorations achieved complete seating with good adaptation.

conclusionsMJ technology achieved high dimensional accuracy in implant-supported crowns with complex structures, outperforming SM in critical regions. Besides RMS values, maximum deviations in key contact areas are also clinically important, as excessive peaks may cause seating interference.
