During the occlusal scan, the maxilla and mandible data begin to align quickly with the occlusal data. When the maxilla and mandible are completely aligned to the optimal occlusal position, the occlusal scan data turns green.
We recommend a left and right occlusal scan for full arches. You can manually sort the occlusion if automatic occlusion alignment is not possible depending on the scan data.
Why Does Occlusal Data Need Compensation?
Occlusion compensation is essential to find the optimal occlusion when scanning a patient’s mouth.
When scanning the maxilla and mandible, there is no bite force applied to the antagonist; therefore, the periodontal ligament is relaxed during scanning.
However, during the occlusal scan, the position of the periodontal ligament changes depending on the patient’s bite intensity. Because of this, there may be slight differences in the maxilla, mandible, and occlusal scan data. This difference can vary depending on how strong the patient bites down or how shaky each tooth is.
For this reason, teeth from the maxilla and mandible may penetrate each other when occlusal alignment occurs. Additional processing algorithms are used in the "Completion Stage" to address these issues and help you find the optimal occlusal relationships. You can reduce chair time when setting prostheses by adjusting the occlusion alignment option while analyzing the scan data’s occlusion.
