5.3 Scanning
Note:

• Pay attention to the guidance and notes in the software interface.
• If necessary, ask the patient to keep the tongue still and move it to the other side, so as to avoid unnecessary influences.
• Hold the scanner steady on the tooth surface and keep the scan tip window 15 mm away from the teeth.
• When scanning, slowly move the scanner along with the dental arches and simultaneously check the scan results on the screen to ensure high-quality scanning.
• To scan the occlusal surface of the teeth, hold the scanner parallel to it; to scan the buccal and lingual surfaces of the teeth, hold the scanner at a 45-degree angle.
• Please pay attention to the device and the patient’s status. If there are abnormalities or warning messages,
• please stop scanning immediately and consult the technical support.
• When scanning, change the scanning angle to 35-55 degrees to create overlaps. It is important to achieve an overlap of at least 30% between each acquisition. If the overlap is small, the jaws may fail to align.
• A complete scan data of a single area includes the surfaces of occlusal, lingual, buccal, interproximal contacts of the adjacent teeth, and 2-3 mm buccal gingiva.
• A complete scan data of a single case includes the lower jaw, upper jaw, and bites.

Scan upper jaw

1. Please ensure that the image of the camera window in the upper left corner of the software is displayed normally. Click or press the Space key or press the scanner body button to start scanning.

Function	Description
	Enabled during intraoral scanning. When it is enabled,  iscellaneous data, including buccolingual data and soft tissues data, will be deleted automatically. When you use the software for the first time, it takes 1~2 minutes to initialize this function. Left image: Function disabled. Right image: Function enabled.

Note:
The green box in the middle of the software interface indicates the data range of the current scanning. If he green box turns into red, the scanned position is incorrect. Please move the scanner tip to the position where displayed in the red frame.
When the scanning is paused or finished, areas which are not been scanned on the model will turn into green. Users can rescan the corresponding areas according to the demand.
When the scanning is paused, you can click to edit data.
Once enough data has been scanned, click or long press the Space key or press the scanner body button to process and save the data.
When it is completed, the upper jaw icon is green and ticked with a , indicating that the scanning process is finished.
Scan lower jaw
After the upper jaw scanning and the data processing are completed, the lower jaw scanning interface is automatically displayed. The procedure is the same as scanning the upper jaw.Scan bite
After the lower jaw scanning and the data processing are finished, the bite scanning interface is automatically displayed.
Click or press the Space key or press the scanner body button to start scanning. After scanning some data, the software automatically performs dynamic bite alignment.
After the upper jaw and the lower jaw are successfully aligned to the bite, click or press the Space key to pause the scanning and check the occlusion.Click or long press the Space key or the scanner body button for about 3 seconds to post-process the data.

To limit exposure to electromagnetic interference from nearby equipment that can degrade image quality or launch warning messages, it is necessary to position the scanner further from sources of electromagnetic interference or install electromagnetic shielding to block unwanted interference.
Customers or the users of the scanner should operate the device under EMI conditions that minimize power supply transients, mechanical interactions, vibration, and thermal, optical, and ionizing radiation.
Separation distances
The scanner is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. Based on the maximum output power of the communications equipment, the customers or the users of the scanner can prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the scanner, as recommended below.
The medical electrical equipment is suitable for the professional healthcare environment per IEC 60601-1-2. It is suitable for use in physician offices, clinics, hospitals, and other professional healthcare environments except near HF surgical equipment and the RF shielded room of an ME system for magnetic resonance imaging or other environments where the intensity of electromagnetic disturbances is high.
Warning:
Using cables or accessories other than those specified for use with the scanner might result in increased emissions or decreased immunity of the device.
Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of the scanner, including cables specified by the manufacturer. Otherwise, it could lead to degradation of the performance of this equipment.
If immunity test level is higher than those specified in IEC60601-1-2, the minimum separation distance may be lowered. Lower minimum separation distances shall be calculated using the equation specified in IEC60601-12 Chapter 8.10.
7.3 Biological safety
The scanner meets the following biological standard:

1. ISO10993-5: 2009 (Biological evaluation of medical devices — Part 5:Tests for in vitro cytotoxicity)
