Article in Technology and health care : official journal of the European Society for Engineering and Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It carries an expression of concern. Cited by 3 papers.
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
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
BackgroundThe increasing demand for dental implants necessitates the exploration of advanced materials and manufacturing techniques. Three-dimensional (3D) printing has emerged as a viable method for producing custom dental implants, allowing for intricate designs and improved patient-specific fits. This study focuses on the design and structural deformation assessment of 3D-printed dental implants using Finite Element Analysis (FEA). By simulating the mechanical behavior of these implants under realistic loading conditions, we aim to evaluate their performance and predict potential failure points, ultimately enhancing their reliability and longevity in clinical applications.ObjectiveThe primary objective of this study is to conduct a comprehensive design and structural deformation assessment of three-dimensional (3D) printed dental implants using Finite Element Analysis (FEA). Specifically, the study aims to: Evaluate stress distribution and deformation patterns in three 3D-printed dental implant designs under simulated physiological loading.Compare the stiffness, strength, and elastic behavior of PEEK and CFR-PEEK under occlusal forces.Identify failure points in implants and bone-implant interfaces by analyzing high stress concentrations.Predict the biomechanical behavior of a novel dental implant by determining its elastic modulus through finite element analysis (FEA).MethodsThree models 3D were designed to understand stress distribution with different structures using PEEK as biomaterial, with 4 test conditions modeled and compared. An occlusal load was applied (230 N at 90˚ and 30˚) on the implants. Isotropic, linear elastic, and homogeneous were considerate as properties of the components.ResultsUnder axial loads, all models stayed within physiological stress limits, while under 30° oblique loading, Model 3 showed the lowest stress, strain, and pressure.ConclusionsFEA results indicate that 3D-printed dental implants, particularly the optimized Model 3, maintain safe stress levels under axial and oblique loads, supporting their potential for immediate loading. However, due to numerical limitations, experimental validation remains necessary to advance implant designs that optimize bone regeneration and material efficiency.
