As of 4/26/2018, we've received some reports that the Charting Element isn't displaying properly in the EDR Ability. This issue seems to only impact users on macOS High Sierra.
Our engineers are hard at work investigating the issue, but currently we don't have a workaround. You can still access your Dental Charts via the Patient Ability > Dental Tab.
This article will be updated with more information as necessary. If you have any questions or concerns, don't hesitate to contact MacPractice Support.
