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

objectivesTo evaluate the accuracy and surgery time of dental implant placement using a novel dynamic computer-assisted implant surgery (dCAIS) system that eliminates the need for patient registration and optical tracking markers. The secondary objective was to compare these outcomes with those obtained using a conventional dCAIS system. MATERIALS AND

methodsA preliminary retrospective cohort study was conducted involving 33 participants (33 implants). Eleven implants were placed using the novel dCAIS system that determines patient positioning based on anterior tooth anatomy (Prototype group), while 22 implants were placed using a conventional dCAIS system requiring standard registration and an optical tracking marker (Control group). Pre- and postoperative cone-beam computed tomography (CBCT) scans were superimposed to assess implant placement accuracy. Descriptive and bivariate analyses were performed to compare accuracy and surgery time between the two groups.

resultsMean angular deviations were similar between groups (p = 0.924): 1.95° (SD 1.38) in the prototype group and 2.38° (SD 2.30) in the control group. No significant differences were observed in platform global deviation (mean difference [MD]: -0.33 mm; 95% CI: -0.75 to 0.09), apex global deviation (MD: -0.43 mm; 95% CI: -0.94 to 0.08), or apex depth deviation (MD: 0.28 mm; 95% CI: -0.30 to 0.86). Surgical procedures were significantly faster in the prototype group (p = 0.002; MD: 3.0 min; 95% CI: 0.56-5.45).

conclusionsThe findings of this preliminary study seem to suggest that the tested prototype dCAIS system may be feasible to accurately place implants without conventional registration or optical tracking, potentially reducing surgical time. However, these findings should be interpreted with caution due to the study limitations.
