Dear Sirs, I am trying the Sato posterior oclusal plane (POP), between palatal plane (Ans-Pns) and cuspid of upper 5-upper 7, I am getting wrong measurements. Look on the picture attached to the yellowlines, I am obtaining an extremely high angle value. I am posting in a next post the print screen of the angle construction on the software, since this forum does no allow to publish more then one image per post (..by the way, that is a simple issue that could be sorted shortly). I have the same issue with another measurement, the Sato´s anterior occlusal plane (angle between palatal plane and upper 5 - upper 1). But let focus on sorting the POP right value.
Can anyone help me so I can f…

Thank you for the question. Doctor. Looking at the custom measurement you made, we confirmed that you defined them using extra additional landmark functions as well. We see that as a high-difficulty function, and it seems to be used properly by you, so I think it is surprising and wonderful. It seems to be the correct way to basically define custom measurement using extra landmakrs. However, it seems that it can be used correctly if you understand the way of defining measurement of the angle between line segments composed of four points.

I will explain by referring to the picture above. Assume that upper5 is defined as Extra2 and upper7 is defined as Extra3. In that case, the POP measurement value you want to measure must be defined as follows so that the angle can be output correctly.

Point A: PNS / Point B: ANS / Point C: Extra3 / Point D: Extra2

As shown in the figure above, the angle between line AB and line CD is developed to measure the clockwise direction in the + direction, and the order of each point is also an important factor. I hope this explanation is helpful to you. If you have any further questions, feel free to contact us. Many thanks. Doctor.

POP it's not related to palatal plane. It's related to Frankfurt Plane
Dear Sirs,
Would like to suggest adding models analysis with AI to the premium package.
Many thanks
WebCeph Manager
Dear Doctor. Thanks for your opinion. The model analysis feature is included in the development plan. We will focus on research and development to add that function. Thanks for using WebCeph.
Dear Sirs,
PA Rx, frontal photo and lateral photos analysis with AI don´t became saved. So if you go out after doing the analysis you have to click to analyse all over again. For example, on Lateral Rx analysis, that does not happen, and if I como back to the program after go out, the analysis I did is saved. Can you check please?
Many thanks

Dear Doctor. Thanks for the question. Premium users are provided with the features to save PA cephalometric landmarks. However, the function of saving landmark points is not yet provided in the lateral face analysis and frontal face analysis tab. Saving functions in the lateral face analysis and frontal face analysis functions will be developed and provided in the future. Thanks for using WebCeph.
Dear Sir,
When I align my analysis with FH plane some of the measuremnts change value, because the extra points does not acompain the rotation of the xray, when th system does the alignment of the Xray with FH plane

Cannot place either more than 1 image on the posts. Would be nice if it allows to upload mor than 1 image.. I have the image with the values changed afyet align to FH plane but I am unable to upload it on this post..even the coments does not have an option to upload images. Can you have a look please?
WebCeph Manager
Dear Doctor. Thanks for reporting the problem. We will review the issue and try to fix it. We will also improve the ability to upload multiple images to a post. Thanks for using WebCeph.

Hello. On the analysis assistant I can't find the angle Oclusal Plane - Frankfurt plane. Can you help? Many thanks
WebCeph Manager
Dear doctor. Thanks for the question. The measurement corresponding to the angle of the occlusal plane with respect to the Frankfurt horizontal plane is the 'Cant of occlusion plane' of the Downs analysis method. If you select and add 'Cant of occlusion plane' from the measurement library of the analysis wizard page, you can check that desired angle is added in your custom analysis method in the analysis tab. If you want to specify or change the name of the measurement, we recommend that you create it yourself using the custom measurement wizard. Thank you for using WebCeph. Doctor.

Dear doctor. Thanks for the question. If we modify the reference value for the APDI, it would affect all the other users who are currently using it. So, we recommend that you create your APDI value in Measurement Wizard following the image I attached below, and modify the reference data for that measurement. If you have any difficulty creating the custom measurement, please contact admin@assemblecircle.com. Thank you very much.
