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

The effect of implant tilt and transmucosal abutment angulation on stress distribution around tilted dental implants in a simulated maxillary arch using Finite Element Analysis (FEA). Eight 3D models with varying implant tilts (17°, 25°, 30°, 35°) and abutment angulations (17°, 30°) were analyzed under a 200 N vertical load. Matched angulations (e.g., 17°/17°, 30°/30°) showed more uniform and favorable stress distribution. Angular mismatches greater than 5° significantly increase stress in abutments and crestal bone. Implant tilts beyond 30° combined with mismatched abutments may compromise biomechanical stability and prosthetic success.
