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

objectiveThis finite element analysis study aimed to compare the biomechanical performance of implants made from polyetheretherketone (PEEK), 30% short carbon fiber-reinforced PEEK (30% SCFR-PEEK), 60% continuous carbon fiber-reinforced PEEK (60% CCFR-PEEK), and titanium in a full-arch fixed implant restoration for the edentulous maxilla.

methodsA three-dimensional finite element model of an edentulous maxilla was constructed from Cone-Beam Computed Tomography (CBCT) data. The bone was modeled with a 2 mm cortical layer surrounding a cancellous core. Four implants supporting a full-arch prosthesis were simulated. Implants materials were assigned properties from literature (PEEK: 4.1 GPa; 30% SCFR-PEEK: 18 GPa; 60% CCFR-PEEK: 150 GPa; titanium: 110 GPa). Three occlusal loading conditions (centric, lateral, protrusive) were applied. The maximum von Mises stress values and stress distribution in the implants, cortical bone, and cancellous bone was analyzed.

resultsImplant stress was highest in 60% CCFR-PEEK, followed by titanium, 30% SCFR-PEEK, and PEEK. Cortical bone stress was lowest around stiff implants (60% CCFR-PEEK, titanium) and highest around PEEK and 30% SCFR-PEEK. The 30% SCFR-PEEK group showed the smallest implant-bone stress gradient and the most uniform stress distribution.

conclusionThe 30% SCFR-PEEK implant exhibited superior biomechanical compatibility for maxillary complete-arch rehabilitation. Its intermediate stiffness promoted physiological stress transfer to peri-implant bone.
