Effect of different restorative design on stress concentration of lithium disilicate and monolithic zirconia endocrown on a mandibular molar - a finite element analysis.

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 purpose of this simulation study was to evaluate effect of different restorative design on stress concentration of endocrown. Different restorative materials were used on a mandibular molar using a finite element analysis.
methodsA 3D FEA model of mandibular molar was constructed using the average values and was used in this analysis. 2 materials were used which were lithium disilicate and zirconia and 2 different margin design of knife edge and shoulder margins were used in various combinations of material and margin design. A constant 12° of internal wall angulation was considered for all the 4 models and a uniform cement thicknes of 100 μm was considered. A uniform 2 mm of bulk fill composite was used as a base beneath the endocrowns. 300 N load was applied on the cusps for each model and linear static analysis was carried out.
resultsEndocrowns of lithium disilicate was found to exert a greater stress concentration in comparison to zirconia endocrowns in both the margin designs of knife edge and shoulder. Knife edge margins were seen to yield greater stress concentration on the remaining tooth structure in comparison to shoulder margins in endocrowns of both the materials used.
conclusionThere is a positive influence of margin design selection within the same material used for the fabrication of endocrown.
