Titanium implant samples in each group were maintained in 75% ethanol for 7 days. After dehydration through a graded series of ethanol and 100% acetone, the samples were embedded in polyester resin. We obtained 200 μm undecalcified sections with a sawing microtome (Leica SP 1600; Leica Microsystems, Wetzlar, Germany), and then polished these sections until a thickness of 100 μm. Images were captured using a fluorescence microscope (Leica Microsystems). After the fluorescence observation, the sections were stained with methylene blue/acid fuchsin and analyzed with a digitized image-analysis system (Leica Microsystems) coupled to a light microscope (Olympus Corporation) with a high-resolution video camera (card digital camera/red green blue color video camera; Sony) and a Trinitron monitor (Sony). BIC was calculated as the linear percentage of direct BIC to the total implant interface in the cancellous bone.
Trinitron monitor
Manufactured by Sony
Sourced in Japan
The Trinitron monitor is a type of cathode-ray tube (CRT) display technology developed by Sony. It features a unique in-line electron gun design and aperture grille construction, which provides a high-quality, high-resolution image. The Trinitron monitor is primarily used as a display device for various electronic equipment, including computers, televisions, and video game consoles.

The experiments were carried out in parallel on different subjects (see later) in two different locations, one in City University and the other in the Max-Planck Institute for Metabolism Research, Cologne. In both cases, eye recording was carried out using the same model of the EYELINK 1000 system (see later). Also in both cases, stimuli were generated by identical scripts in Matlab on the same model of MacBookPro computer, running MATLAB and using the PSYCHTOOLBOX PTB3 software (Brainard, 1997 (link)). In Cologne, stimuli were presented on the screen of SONY Trinitron monitor with resolution 1400 × 1050 pixels and viewed at 75 cm so that 45 pixels subtended 1° of visual angle. The background screen luminance was 16 cd/m2, with average luminance of the stimulus components being 49 cd/m2. In London, stimuli were presented on a vertically oriented Protouch 17-in. TFT flat-screen display. On-screen pixel size was 0.36 mm, and average background luminance was 55 cd/m2, while average luminance of the stimulus components was 130 cd/m2. The difference in geometry between the two displays was taken account of in the eye movement analysis.

All experiments were conducted in a quiet and dimly lit environment. Visual stimuli were generated using MATLAB 7.0 (MathWorks, Natick, MA) with Psychotoolbox-3 extensions (Brainard, 1997 (link); Pelli, 1997 (link)). All stimuli were presented on a 21-inch Trinitron monitor (1024 × 768 spatial resolution, 60-Hz refresh rate; Sony, Tokyo, Japan) with a gray background (mean luminance, 49.98 or 40.65 cd/m2). The output luminance of the monitor was linearized using a look-up table in conjunction with photometric readings from a colorCAL colorimeter (Cambridge Research System, Kent, UK). Subjects viewed the stimuli from a fixed distance of 68 cm. Their head position was stabilized with a chin rest and a forehead bar.

Stimuli were presented on a 60-Hz frame-rate Sony Trinitron monitor in a darkened room, viewed from 0.75 m, so that one pixel subtended 1.275 arcmin at the observer’s eye. Viewing was binocular through natural pupils, with observers wearing their normal correcting lens for the viewing distance if necessary. A total of five observers participated in the experiments, comprising the two authors and three other experienced psychophysical observers from City, University of London, who were naïve as to the purpose of the experiment. Note that we report only within-observer statistics. Our five observers’ performances need not and should not be considered representative of the population at large.

In all three experiments, visual stimuli were displayed on a Sony Trinitron monitor (refresh rate: 100 Hz; spatial resolution: 1024 × 768; size: 19 inch) with a gray background (luminance: 47.59 cd/m2). Particularly, visual stimuli used in experiment 3 were rendered with a video card with an 8-bit input resolution and a 14-bit output resolution using Cambridge Research System Bits++. The output luminance of the monitor was linearized using a look-up table in conjunction with photometric readings from a colorCAL colorimeter (Cambridge Research System). The viewing distance was 70 cm, and we used a head and chin rest to stabilize subjects’ head position. Subjects were asked to maintain fixation on a black dot at the center of the display and their eye positions were monitored with an Eyelink 1000 Plus eye-tracking system during the experiments. Subjects could maintain their fixation very well across experiments and stimulation conditions.

Ten samples in each group were maintained in 75% ethanol for 7 days. After dehydration through a graded series of ethanol and 100% acetone, the samples were embedded in polyester resin. We obtained 100 μm-thick undecalcified sections with a sawing microtome (Leica SP 1600; Leica Microsystems, Wetzlar, Germany), and then images were captured using a fluorescence microscope (Leica Microsystems).
After the fluorescence observation, the sections were stained with methylene blue/acid fuchsin and analyzed with a digitized image-analysis system (Leica Microsystems) coupled to a light microscope (Olympus Corporation, Tokyo, Japan) with a high-resolution video camera (CDC/RGB color video camera; Sony) and a Trinitron monitor (Sony). Bone–implant contact (BIC) was calculated as the linear percentage of direct BIC to the total implant interface in the cancellous bone.

Stimuli were presented on a 60-Hz frame-rate Sony Trinitron monitor in a darkened room, viewed from 0.75 m, so that one pixel subtended 1.275 arcmin at the observer's eye. Viewing was binocular through natural pupils, with observers wearing their normal correcting lens for the viewing distance if necessary. A total of 12 observers participated in the experiments, comprising the two authors and a number of postgraduates/undergraduate students from City, University of London and the Max-Planck Institute for Metabolism Research at Cologne, all of whom were naïve to the purpose of the experiment. Two of the participants were paid volunteers.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
