Custom-made 3D PEEK plates versus 3D titanium plates for mandibular angle fracture fixation: a randomized clinical trial.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07156812 (Custom-Made 3D PEEK Plates Versus 3D Titanium Plates in Mandibular Angle Fracture Fixation), which is not on this map. Not yet cited in PubMed.
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.
The trial behind it

Abstract
aimThis study aimed to determine the clinical and radiographic efficacy of custom-made 3D PEEK plates in comparison with 3D titanium plates for the management of mandibular angle fractures. PATIENTS AND
methodsEighteen patients with recent mandibular angle fractures indicated for open reduction and internal fixation were randomly allocated into two groups. The study group (n = 9) underwent fixation with custom-made 3D PEEK plates, while the control group (n = 9) received prebent 3D titanium plates adapted on virtually reduced models. Primary outcomes were bite-force recovery and bone-density (Hounsfield units, HU) at the fracture line measured on CT immediately post-op and at 12 weeks. Secondary outcomes included operative time, occlusion, interfragmentary stability and wound healing.
resultsBy the end of follow-up, Bite force increased significantly over time in both groups (p < 0.001) with no between-group differences at any time point. Mean bone density increased from 811.1 ± 68.2 HU to 1225.1 ± 111.7 HU in the PEEK group and from 809.0 ± 62.1 HU to 1248.3 ± 92.3 HU in the titanium group (p < 0.001); between-group differences were not significant. Operative time, occlusion outcomes and wound healing were similar between both groups.
conclusionCustom-made 3D PEEK plates achieved comparable clinical, radiographic, and functional outcomes to 3D titanium plates, suggesting that PEEK is a viable alternative for mandibular angle fracture fixation.
