Hi everyone, recently I need to perform gingivoplasty to a patient with severe gingival hyperplasia. But the first thing I should do before the actual surgery is to mark the CEJ (cement-enamel-joint) on patient’s gingiva. As the image shows, I decide to measure the distance of tooth cusp to CEJ.
For each tooth, I measured 6 points (buccal and palatal, mesial/middle/distal).
But when I tried to used the above data to perform surgery, I found out for the posterior teeth, the actual distance between the tooth cusp to CEJ is greater(1~2mm) to what I measured in the slicer 3D software. I think it might be caused by the curved surface. So I wonder if there is a more accurate way of measuring this kind of distance.
