After photographing the oral cavity with a camera, the plaque adhesion state was evaluated. Plaque adhesion was measured by using the O'Leary PCR. The crown was divided into six surfaces, i.e. the mesial, central, and distal regions of the labial/buccal and lingual/palatal sides, and the presence or absence of stained regions was confirmed. After calculating the PCR, the dentition was scanned with an IOS (TRIOS 3 Basic, 3Shape, Copenhagen, Denmark). The plaque adhesion state was observed on a 3D image, and PCR evaluations were again performed for the screen image. The evaluation time was not specified. These measurements were performed by a single dental hygienist with greater than 15 years of experience in dental hygiene.
Trios 3 basic
Manufactured by 3Shape
The TRIOS 3 Basic is a dental intraoral scanner designed for digital impressions. It captures highly accurate 3D images of the patient's oral cavity, which can be used for various dental procedures such as restorations, aligners, and implants. The scanner is lightweight, portable, and features intuitive software for easy operation.

The model of the upper arch was made of resin extending from half of the first molar to half of the first molar. The 18% gray color of resin was selected to reduce the scattering light around the samples. The space of the right central incisor (tooth number 11) was prepared to replace by milled restorations fabricated by CAD/CAM. To fabricate the central incisor, first, the model was scanned by an intraoral scanner (Trios 3 Basic, 3Shape®, Copenhagen, Denmark). Second, the STL files were used to fabricate 30 milled restorations. Vitablocs® mark II (VITA Zahnfabrik®, Bad Sackingen, Germany) which is a monochromic feldspar ceramic was utilized because of the various shade providence in the market. Nine possible VITA 3D-Master shades including 1M1, 1M2, 2M1, 2M2, 2M3, 3M1, 3M2, 3M3, and 4M2 were used to fabricate 30 teeth. The identical size and shape of those milled restorations were double-checked by the measurement from the vernier caliper. The tooth was retained in the model by friction to minimize the adjustment of the restoration and the referent points were marked. The cross-section of the imaginary lines, at the middle third of the tooth, was indicated as a shade measuring point (Figure 3 ).

Images of the models were captured using an intraoral scanner (TRIOS 3 Basic, 3Shape A/S, Copenhagen, Denmark) and saved in standard tessellation language (STL) format. Furthermore, a cone-beam computed tomography (CBCT) scan (Accuitomo 170; Morita Manufacturing Corp, Kyoto, Japan) of each model was obtained at 80KV and 6 mA using a voxel size of 250 μm and a field of view (FOV) of 10 × 10 cm. The CBCT images were exported in Digital Imaging and Communications in Medicine (DICOM) format for further planning.

The models were first scanned with the 3Shape TRIOS scanner (TRIOS 3 Basic, 3Shape, Copenhagen, Denmark) for the control group, following the manufacturer's scan strategy protocol [25 (link)]. The three-dimensional (3D) scan of the cast had to be transferred into a two-dimensional (2D) representation so that linear measurements could be compared between the scan and the photographs. To do so, a frontal view of the scan had to be chosen so that it matches the frontal view depicted on the photographs. A see-through 2D square with gridlines dividing the square into thirds was superimposed on the scan, and the frontal view was chosen when the edges of the scanned model fit in the square and the base of the model coincided with the lower horizontal line of the grid.

Digital impressions were taken by TRIOS 3 basic (3Shape, Copenhagen, Denmark) to mimic the clinical setting. Following the manufacturer’s recommendations, scanning of the reference model and opposing model and a buccal scan of the interarch relationship were carried out. Scans were exported to obtain the final virtual 3D master model as shown in Figure 1 , and they were used to fabricate the test models and design the provisional dental prosthesis using CAD/CAM technology [24 (link),40 (link)].
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.
