I got an interesting request from a Dentist, she wanted a Pendulum with removable activation arms. On top of that, she wanted 4 of them! We discussed the case a bit over the phone and she said she will send along some information with the case. When I got the case and the information, I was very impressed, these are how all pendulums should be made from now on! It has removable activation arms that the doctors can activate outside the mouth. no more awkward in-mouth activations! It was easy to do, it is just basically imbedding tubes into the palatal acrylic, but you can see the rest from the pictures. THe 4 armed one turned out good, I think for my first try. We will see how it goes in the patients mouth…
