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

backgroundStudies have assessed the impact of Invisalign on maxillary molar distalization; however, varying results were reported.

methodsBy using the iTero intraoral laser scanner to obtain three-dimensional (3D) digital models and using the palatal area for the registration of models, the position and angulations of the maxillary first molar (U6) and second molar (U7) were determined before treatment (T0), after U7 distalization (T1) and after U6 distalization (T2). In addition, the rotation angle and vertical changes of U6 and U7, and the sagittal and torque changes of the maxillary central incisor (U1) were determined from T0 to T2.

resultsThe U6 was moved distally from T0 to T1, T1 to T2, and T0 to T2, by 0.91 ± 0.80 mm, 0.80 ± 0.49 mm, and 1.71 ± 0.89 mm, respectively. Similarly, the U7 was moved by 2.25 ± 1.30 mm, -0.21 ± 0.78 mm, and 2.04 ± 1.16 mm, respectively. From T0 to T2, the U6 and U7 molars were distally tipped by angles of -5.20 ± 2.62° and - 5.35 ± 4.19°, respectively. Molar intrusion and loss of anterior anchorage were also observed.

conclusionsInvisalign can achieve maxillary molar distalization primarily through tipping movement, often accompanied by decreased angulation control and anterior anchorage loss, which requires additional auxiliaries to strengthen anchorage.
