Correlation between abutment angulation and off-axial stresses on biomechanical behavior of titanium and zirconium implants in the anterior maxilla: A three-dimensional finite element analysis study.

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
aimThe aim of the present study was to evaluate the stress distribution around the titanium and zirconium implant with different abutment angulations in the anterior maxilla to off-axial load. SETTING AND
designMATERIALS AND
methodsTwo models of titanium and zirconium implants (4 mm × 13 mm) and abutment with at 0°, 15°, 25° angulations were modeled to replace missing right central incisor using three-dimensional finite element analysis. A bite force of 178 N was applied on the lingual fossa of crowns at an angle of 120° off-axial to the long axis of implant. STATISTICAL ANALYSIS USED: Nil.
resultsVon Misses stresses observed are as follows: (1) at the implant-bone interface Ti 0 (8.31 MPa), Zr 0 (8.57 MPa), Ti 15 (83.59 MPa), Zr 15 (98.07 MPa), Ti 25 (197.8 MPa), and Zr 25 (265.77 MPa); (2) at the implant-abutment interface Ti 0 (5.90 MPa), Zr 0 (6.45 MPa), Ti 15 (19.13 MPa), Zr 15 (19.32 MPa), Ti 25 (38.65 MPa), and Zr 25 (38.26 MPa); and (3) within superstructure Ti 0 (3.11 MPa), Zr 0 (5.02 MPa), Ti 15 (6.17 MPa), Zr 15 (5.02 MPa), Ti 25 (8.15 MPa), and Zr 25 (6.131 Mpa).
conclusionStress behavior of titanium and zirconium implant with tested abutment angulation at implant-abutment interface and within the superstructure was similar, except at implant-bone interface.
