Biomechanical Response Analysis of Scaffold Implantation in Mandibular Defects and Research on Scaffold Selection.
Article in ACS omega, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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
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
This study aims to optimize the structural design of porous titanium alloy scaffolds for mandibular defect repair. It investigates the impact of different scaffold structures on the biomechanical properties of both the scaffold and surrounding bone tissue. Finite element models of rabbit mandibular defects were first established. Custom porous titanium alloy scaffold models were subsequently designed using diamond (DI), cubic (C), and truncated cubic (TC) unit cell structures. Additionally, the structural design of the scaffold can be adjusted based on the mechanical properties of the cellular structure. A porous titanium alloy scaffold featuring a composite unit cell structure was developed. Finite element analysis was then performed to obtain the biomechanical response characteristics of both the scaffolds and the surrounding bone tissue at the defect sites. The unit cell structure significantly influences the stress, strain, and spatial distribution in both the scaffold and the surrounding bone tissue. Comparative analysis demonstrates that scaffolds with composite unit cell structures possess superior overall mechanical properties and deliver optimal biomechanical stimulation, thereby promoting new bone regeneration. These findings provide a theoretical basis for optimizing the scaffold's structural design.
