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

Posterior tooth loss disrupts occlusal support, mandibular kinematics and elevates TMJ loading and TMD risk. Therefore, it is of interest to used 3D FEA and dynamic condylar analysis in 42 unilateral posterior edentulous patients across implant (n=15), RPD (n=14) and untreated (n=13) groups. Implant restoration reduced peak condylar cartilage stress 41.2% (18.7±4.1 to 11.0±2.6 MPa, p<0.001) and disc stress 38.7% (p<0.001), unlike RPD/untreated controls. Clinical TMD prevalence dropped from 66.7% to 13.3% in the implant group versus minimal change elsewhere. Implants uniquely normalize TMJ biomechanics and halt TMD progression, advancing evidence-based posterior restoration protocols.
