If you are designing any implant restoration in 3shape, then there could be chances that you have received the error message “Abutment Top Cap Angle Violated” when trying to finalize your design.

We see this question come up on a weekly basis and there are lots of 3shape users out there who receive this message.

Solution to Fix Abutment Top Cap Angle Violated in 3shape:

Alright! Now let’s take a look at how we solve this issue. Just follow the steps below or the ones found in the infographic above and you’ll be well on your way.

Note: This solution involves modifying material files and may corrupt your order and make it unusable if not properly edited. We take no responsibility for any problems this may cause to your dental system and it is advisable to make a backup of your order before proceeding

Step 1: Firstly you’ll see an error saying Abutment Top Cap Angle Violated

Error: Angle between implant direction and abutment top cap direction is more than the maximum limitation (30°) Message code [1:25]

This generally happens because there’s an error with how the implant insertion direction detects the transformation during the design. No actual limitation has been violated.

Step 2: Close The Case and Explore in Windows

You’re going to want to close the case, save the design to speed up the redesign process later if you’re prompted to do so. Once the case is closed, go to Dental Manager and highlight the case, right click and advanced > explore order, or simply press F4 on the keyboard as a shortcut to open the case folder in Windows Explorer

Step 3: Locate & Open Materials.xml File

Locate the Materials.xml file in the Explorer folder and right click on the materials file > Open With > Notepad. (Alternatively you can use a dedicated xml editor, the one I use is XML Copy Editor)

Step 4: Edit Materials.xml File

In Notepad, press ctrl+f to open up the search dialog box. In the search field type Maxtilt and press enter. (Note: For a simple single implant case, you will have one result, for multiple abutments or multiple arches, you will have multiple results that you will need to modify). Once the result is found, simply change the value from “30” to “70”

After the changes have been made, go to file > save, or hit ctrl+s to save your changes and close notepad.

Finally, re-open the case and proceed with the design!

Problem Solved!
