Medit Link

Medit Link is an integrated dental platform which allows clinics and labs to connect and do business with each other. It provides cloud storage and simple sharing of cases and scan data, as well as easy integration of CAD software. Additionally, contracts, orders, and payments can be completed on Medit Link.


It is designed to provide different services according to your business needs as a clinic or lab. Access to specific functionalities can also be controlled by the account type of administrator or member. Medit Link helps users systematically manage a series of digital dentistry workflows including the scanning process with the DiOS 4.0 (i500) intraoral scanner, the ordering of prostheses and the manufacturing process for dental prostheses using our user-friendly menu system which is composed of Case Box, Order Box, In Box, and Work Box.

Medit Link & iScan

Medit Link helps you manage scan data from the DiOS 4.0 (i500), ensuring a smooth scanning process using the iScan. In addition, you can easily place orders by generating information from iScan. Once the scan is complete, it automatically uploads the scan files to the cloud and facilitates the order and payment process with the partnered or contracted dental labs.

Order

It streamlines your order process based on the data generated by Medit Link while allowing you to negotiate order items and prices with dental labs in advance by processing contracts.

Cloud Service

Medit Link supports automatic upload/download of database and files through AWS (Amazon Web Services). As a result, data is automatically synchronized to the computers of multiple users in the organization, so they can access the data anytime from any computer which has the Medit Link software installed.

Security

All patient data is encrypted for secure storage and transmission to ensure compliance with HIPAA and GDPR, as well as applicable medical laws.


There is no limit to the number of computers you can connect and use the DiOS 4.0 (i500) with. You can log in to the Medit Link software to operate the scanner in multiple workstations if the Medit Link application has been installed on the computer.


No, you do not have to continuously hold down the button while scanning. Press once to begin scanning and press again to end the process.


The DiOS 4.0 (i500) has a sleep mode feature which switches the scanner off automatically after 30 seconds of inactivity. The DiOS (i500)’s projector will automatically be switched off after it has been left idle for 30 seconds in order to preserve the lamp’s lifespan.


The Medit Link application supports the offline mode in cases where your network is unstable or unavailable. Only clinic accounts can access this feature. While using the offline mode, the user will be able to use almost all the iScan features required for scanning, except for making orders, deleting cases, and modifying patient information.


1. Start the Medit Link application.


2. Click My Information at the bottom-left corner to open the My Information window.


3. Turn on the Work Offline option.

  • When the PC gets connected to an online network while in offline mode, or when you manually switch back to the online mode, the off-line mode will be terminated, and the file synchronization process will be reinitiated.
  • There is no time limit to use the Medit Link application in offline mode; however, there is a 30-days limit for iScan.
  • The off-line mode is available only for accounts that have previously logged in to the Medit Link website at least once. If a user has never logged in to the website, the off-line mode option will not be made available.

Offline mode is now available for lab accounts.

 ⚠️ The cases created in online mode can not deleted in offline mode.


1. Click the Network Status icon in the title bar.


2. Enable/disable Work Offline.

(1) Network status: Good, Fair, Poor, and Disconnected.

  • Depending on the network performance, the upload speed may alter.

(2) Indication of sync status

(3) Enable/disable offline mode.


When you scan while connected to the internet, the scan data will be stored locally and automatically uploaded onto the cloud. When scanning in offline mode, however, the data will only be stored locally. However, the scan data will be uploaded onto the cloud when the device is connected to the internet.


All scan data captured with the iScan is stored locally on your computer as a “.medit” mesh format. If you wish to store files in STL or OBJ formats, you will need to export them from Medit Link.


Since the Medit Link v2.0 release, the way that iScan displays scan data has been changed; some users may feel that the scan images displayed on iScan seem to be a bit blur compared with those shown on Medit Link. The compensating merit of this change is a highly increased scan speed without losing any scan data quality. The mesh data, which is created after post-processing and saved in the case details of Medit Link, looks crisper than the scan images seen on iScan. As we know, the mesh data is the actual data used for designing dental prostheses. Therefore, if the mesh data is satisfactory, there is nothing to worry about. In case you’re concerned about the reliability of the scan data due to the images being slightly blurry on iScan, you can examine the data by using either the reliability map feature or the result preview function.



The calibration process is essential in producing precise 3D models. It is recommended to perform the calibration process periodically.


Calibration is required when:

  • The quality of the 3D model is not reliable or accurate as compared to previous results.
  • Environmental conditions such as temperature have changed.
  • Calibration period has expired.
  • You can set the calibration period as detailed in Menu > Settings > Calibration Period (Days). The default calibration period is 14 days.

Precautions:

  • The calibration panel is a delicate component. Do not touch the panel directly. When the calibration process is not performing properly, check the panel. If the calibration panel is contaminated, please contact your service provider.

How to Calibrate the DiOS 4.0:

  • Turn on the DiOS 4.0 and connect the device to the software.
  • Run Calibration Wizard from Menu > Settings > Calibration.
  • Prepare the calibration tool and the DiOS 4.0.
  • If the scanner tip is attached, please remove it from the handpiece.

  • Turn the dial of the calibration tool to the position (1).

  • Remove the cover from the calibration tool and put the DiOS 4.0 handpiece into the calibration tool.

  • Click Next to start the calibration process.

  • When the handpiece is mounted in the correct position, the system will automatically acquire the data at position (1).

  • Repeat the same for position (2) to position (8) and finally, (LAST).

  • When data acquisition is completed at the (LAST) position, the system will automatically calculate and show the calibration results.
1. Scanner Tip

The DiOS 4.0 (i500) scanner tip is the part of the scanner that is inserted into a patient’s mouth during scanning. The tip can be reused for a limited number of times but must be cleaned and sterilized between patients to avoid cross-contamination.


– Clean the tip using soapy water and a brush and inspect the mirror found in the tip. If the mirror appears stained, smudged or has a milky haze, repeat the cleaning process using a soft dish brush and soapy water. Carefully dry the mirror with a paper towel.


– Put the tip in a paper sterilization pouch and seal it. Make sure the pouch is airtight by using either a self-adhesive pouch or a heat-sealed pouch.


– Sterilize the wrapped tip in an autoclave with the following conditions:

  • At 121℃(249.8°F) for 30 minutes, and dry for 15 minutes

– Use an autoclave program that dries the wrapped tip before opening the autoclave.

  • Using any other method besides autoclaving does not guarantee the sterilization of the tips.

⚠️ Caution


  • The mirror in the tip is a delicate optical component and should be handled with care. The mirror needs to be clean and free from damage to ensure scan quality. Be careful not to scratch or smudge it before scanning.
  • Do not use disinfectants other than Ethanol or Ethyl alcohol to clean the mirror in the scanner tip or the surface of the scanner body. Chemical cracks may appear if improper disinfectants are used for cleaning.
  • Never autoclave a tip which has not been wrapped as this will leave stains on the mirror which cannot be removed. Check the autoclave manual for more information.
  • New tips must be cleaned and sterilized/autoclaved before using.
  • Each scanner tip can be re-sterilized up to 20 times, after which it should be disposed of properly as described in the section on Disposal.
  • Medit will not be responsible for any damage arising from improper handling.
2. Mirror

If the mirror in your scanner tip is contaminated, it may result in a bad scanning experience or poor scan quality. To clean the mirror, follow the recommended steps below.


– Remove the scanner tip.


– Apply alcohol to a clean cloth or cotton-tipped swab and wipe the tip mirror until it is clean. Make sure to use only alcohol that is free of impurities such as ethanol or propanol (ethyl-/propyl alcohol) to avoid staining the mirror.


– Wipe the mirror dry with a dry, lint-free cloth to avoid leaving dust and fiber on the mirror.


– Make sure the mirror is free from dust or fibers. Repeat the above process as necessary.


⚠️ Caution

  • Do not use disinfectants other than Ethanol or Ethyl alcohol to clean the mirror in the scanner tip or the surface of the scanner body. Chemical cracks may appear if improper disinfectants are used for cleaning.
3. Handpiece

After treatment, clean and disinfect all other surfaces of the handpiece except for the front of the scanner (optical window) as well as the end (air vent hole). Make sure the device is switched off before cleaning and disinfecting. Use the device only after it is completely dry.


– Recommended disinfection solution:

  • Denatured alcohol (e.g. ethyl alcohol or ethanol) – typically 60-70% Alco/Vol.

– The general cleaning and disinfecting procedure are as follows:

  • Switch off the device using the power button.
  • Unplug all cables from the power hub.
  • Attach the handpiece cover to the front of the scanner.
  • Apply the disinfection solution to a soft lint-free, non-abrasive cloth.
  • Wipe the scanner surface with a cloth which has been dampened with disinfectant.
  • Remove liquid with a clean, lint-free, dry, non-abrasive cloth.

⚠️ Caution

  • Do not clean the handpiece when the device is turned on as the fluid may seep into the scanner and cause a malfunction.
  • Do not use disinfectants other than Ethanol or Ethyl alcohol to clean the mirror in the scanner tip or the surface of the scanner body. Chemical cracks may appear if improper disinfectants are used for cleaning.
  • Only use the device after it is completely dry.
4. Other Components

– Apply the disinfection solution to a soft, lint-free, non-abrasive cloth.


– Wipe the component surface with a cloth which has been dampened with disinfectant.


– Remove liquid with a clean, lint-free, dry, non-abrasive cloth.


⚠️ Caution

  • Do not use disinfectants other than Ethanol or Ethyl alcohol to clean the other scanner components. Chemical cracks may appear if improper disinfectants are used for cleaning.
5. Disposal

– The scanner tip needs to be sterilized before disposal. Sterilize the tip as described above.


– Dispose of the scanner tip as you would other clinical waste.


– The other components are designed to conform with the following Directives.

  • RoHS, Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment. (2011/65/EU)
  • WEEE, Waste Electrical and Electronic Equipment Directive. (2012/19/EU)

The scanner tip can be re-sterilized up to 20 times and must then be disposed of properly.


The iScan software provides a fully automated alignment feature. When you scan the bite occlusion, the software will look for reference points of the maxilla and mandible scan data and align them automatically. Alternatively, you can also choose to align them manually by marking the same points onto the scan data where you identify aligning points in the occlusion scan with the maxilla and the mandible. 


How to Align Manually

1. Go to the Tools section and click Manual Alignment.


2. Mark a point on the maxilla or the mandible and mark the same point on the occlusion scan data appearing in grey colour to align them based on the points marked.


3. Scan data has been aligned.

 

Command Option Detail

 Remove Marker Point: Removes the point you recently marked.

 Move Maxilla: Moved maxilla to a non-overlapping position from the 3D model for occlusion alignment.

 Move Mandible: Moved mandible to a non-overlapping position from the 3D model for occlusion alignment.

 Undo: Undoes the previous action.

 Redo: Redoes the previous action.

 


If you have scanned the wrong jaw by mistake, you can easily swap the maxilla and the mandible data.


1. Go to the Tools section and click the Swap Maxilla & Mandible button.


2. Scan data of the maxilla and the mandible have been switched.


Since the iScan software has an intelligent scan detection algorithm, the DiOS 4.0 (i500) can easily fill in blank spots in the scan data at any point of the scanning process. This means that even if you have already reached the occlusion scanning stage, you can still choose to go back to the maxilla or mandible scanning stage and simply cut out the unsatisfactory data to rescan it.


The Lock Area feature allows you to lock a specific area chosen by the Selection tools. Once the data area is locked, further scanning will not affect the shape of the locked area, but the color. This feature is useful when you need to preserve the retracted gingiva data scanned after cord removal.

  1. Go to the Tools section and click the Lock Area button.

  2. Mark the area to lock by using the Selection tools.
    Brush: Selects all entities on a freehand-drawn path on the screen. The brush comes in 3 different sizes.
     Polyline: Selects all entities within a polyline shape drawn on the screen.
     Circle: Selects all entities within a circular area.
     Clear Selected Area: Clears areas selected by a drawn path. The brush comes in 3 different sizes.
     Clear All Areas: Clears all selected areas.


  3. The selected area will be locked and indicated by a different colour.


  4. To unlock the area, follow the following steps:
    – Click the Clear Selected Area button.
    – Select the areas to unlock.
    – If you want to unlock all the areas, click the Clear All button.

The iScan software has an Undercut Analysis feature which you can use to calculate the undercut region by setting the insertion direction or by using the Auto Direction function.

  1. Go to the Tools section and click the Undercut Analysis button.


  2. In the Command Option area, you will see the following selection tools.
    Brush: Selects all entities on a freehand-drawn path on the screen. The brush comes in 3 different sizes.
     Polyline: Selects all entities within a polyline shape drawn on the screen.
     Circle: Selects all entities within a circular area.
     Clear Selected Area: Clears areas selected by a drawn path. The brush comes in 3 different sizes.
     Clear All Areas: Clears all selected areas.


  3. Set the region of interest to calculate the undercut area using the selection tools.


  4. Once you’ve selected the area, click Auto Direction or Manual Direction. These are the two different methods to set the insertion direction.
     Auto Direction: The system automatically calculates the direction in which the undercut area is minimized, then displays the undercut area on the View screen.
     Manual Direction: The system calculates the undercut area based on the direction specified by the user, then displays the undercut area on the View screen.

In general, it is recommended to maintain an optimal speed and distance between the scanner tip and the teeth.

  • In general, it is recommended to set the scan depth between 15mm and 17mm which allows you to acquire the necessary scan data comfortably for most cases. You can adjust the maximum distance of the scan depth between 12mm and 21mm by using the scan depth selector.

  • The live view will show some areas masked in blue when the fields are out of the focus range, which means that the DiOS 4.0 cannot capture scan data from those areas. For an easier and smoother scanning experience, it is always better to position the scanner tip close enough to the surface of the teeth during scanning rather than trying to maintain a certain distance. However, you need to be careful not to cause discomfort to a patient by the tip meeting the teeth.
