Evaluation of biomechanical behavior of all-ceramic cantilever resin-bonded fixed dental prostheses: a finite element analysis.
Article in BMC oral health, 2025. 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
backgroundResin-bonded fixed dental prostheses (RBFDPs) offer a minimally invasive approach while delivering excellent aesthetics and functionality. This study aimed to examine the stress distribution in RBFDPs.
methodsTwo intact natural teeth (#11 and #13) were selected and mounted into a dental model using a silicone mold, with tooth #12 removed to simulate the absence of a maxillary lateral incisor. Four cantilever RBFDP models were created: Model 1, #11 abutment, made of zirconia; Model 2, #13 abutment, made of zirconia; Model 3, #11 abutment, made of lithium disilicate; and Model 4, #13 abutment, made of lithium disilicate. A 200 N occlusal force was applied to the pontic. Finite element analysis (FEA) was performed to quantify the maximum von Mises stress distribution in the framework, cement layer, and periodontal ligament (PDL).
resultsThe maximum von Mises stress in the framework was highest in the zirconia RBFDP with #11 as the abutment (model 1), and lowest in the lithium disilicate RBFDP with #13 as the abutment (model 4). Regarding the cement layer, the maximum von Mises stress was greatest in the lithium disilicate RBFDP with #11 as the abutment (model 3), and lowest in the zirconia RBFDP with #13 as the abutment (model 2).
conclusionsThe canine is a more efficient abutment than the central incisor in terms of maximum von Mises stress in the framework, cement layer, and on the PDL. Regarding the materials used, zirconia showed lower von Mises stress on the cement layer. Therefore, a zirconia cantilever RBFDP with the canine as the abutment is recommended as the preferred choice for all-ceramic cantilever RBFDPs.
