FAQs for occlusion

1. Question

• How can I acquire the accurate occlusal scan data?

1.1. Answer

• Remove unnecessary soft tissues from the maxilla and mandible scan data by using the trimming tools.
• Acquire the occlusal scan data while the patient is seated in an upright position with the occlusal plane parallel to the floor.
• Start the occlusion scan using the rolling method: roll the tip up and down till you scan 3 to 4 teeth from the maxilla and the mandible respectively.
• If there is a missing posterior tooth, alternatively, you can scan the canine area.
• After the occlusal scan, click on Optimize if you wish to check the quick result which is close to the final result that you can view in Medit Link.

 

2. Question

• Why are the occlusal scan data not identical between Medit Scan for Clinics and Medit Link?

2.1. Answer

(A) Through the automatic or manual alignment process, the maxilla and the mandible are put into the initial position for further alignment, the occlusal accuracy of which is not adequate for analysis. If you wish to check the occlusal status before the Complete stage, click Optimize or Occlusion Analysis in the command options.

⚠︎ ENSURE NOT TO READ the occlusal status without performing Optimize or Occlusal Analysis.

(B) The Optimize and Occlusion Analysis feature performs the realignment process for the initially aligned maxilla and mandible scan data, and creates a quick result that is close to the final result.

(C) On the other hand, the Complete stage creates a fully processed result by performing various processes additionally: realignment, data merging, etc. You can check the final result in Medit Link.

 

3. Question

• Does repeating the optimization process improve the accuracy of scan data?

3.1. Answer

• Once the optimization process is properly done with realigning the scan data, repeating it does not affect the accuracy.

 

4. Question

• What should it be done when the maxilla and the mandible is not automatically aligned (The occlusal area doesn't turn green)?

4.1. Answer

• Depending on the scan area or a way to maneuver the scanner, the automatic alignment could sometimes be unsuccessful. In this case, it is required to perform the manual alignment by marking alignment points on the cusps or the area that is clear enough to be identified as different.

 

5. Question

• Is there any difference in the accuracy between the automatic and the manual occlusal alignment?

5.1. Answer

• Both methods are for the initial alignment of the occlusion, therefore there is no difference in terms of the accuracy once the scan data is properly aligned.
• The manual alignment is required when the automatic alignment fails, or can't be performed adequately.
• Through the automatic or the manual alignment process, the maxilla and the mandible are put into the initial position for the further alignment, the occlusal accuracy of which is not adequate for analysis. If you wish to check the occlusal status before Complete, click on Optimize or Occlusion Analysis in the command options.

⚠︎ In Medit Scan for Clinics > Occlusion scan stage, ENSURE NOT TO READ the occlusal status without performing Optimize or Occlusal Analysis.

 

6. Question

• Is there any difference in terms of the accuracy of the occlusion between the 1-point and 3-point manual alignment? 

6.1. Answer

• Both methods are for the initial alignment of scan data by manual. Regardless of the number of alignment points, there is no difference in the accuracy once the scan data is properly aligned.
• The 3-point alignment method is needed when the 1-point alignment method is unsuccessful due to lack of the cusps (or the area that is clear enough to be identified as different).

 

7. Question

• Is it necessary to click on Optimize every time before moving to the next scan stage?

7.1. Answer

• Through the Complete stage, all scan data will be automatically optimized. Therefore you don't need to perform the optimization process by each scan stage.

 

8. Question

• Does it affect the occlusal data if scanbodies are scanned after the maxilla, mandible, and occlusion stage?

8.1. Answer

• Even if scanbodies are scanned after the maxilla, mandible, and occlusion stage, it can't affect any of the occlusal data since the data acquired from the scanbody stage is not used for occlusion.
