rpd guide plane index

[twaite]

Hello,

My doctor is asking me to make a guide plane index. He wants a guide to plane so he can adjust the teeth perfectly parellel. Has anyone made this before?

Is this for a future partial or for preparing for a c&b restoration? If for partial I would think you could create your guide planes on the specific teeth involved then take some light cured tray material and make a jig incoporating those guide planes. The Dr. will then adjust those teeth till the jig seats. Anyone else feel free to break my idea down.

Does this question make sense? He wants to adjust the teeth perfectly parellel for the guide plane of the rpd during the rest prep appointment.

Oh, forgot to mention prepping the guide planes and making the jig on a preoperative model.

One way to do this, is after you survey and design the framework, selected the path of insertion and removal, tripod the cast (or duplicate preferably) first.
Then you lubricate/apply separating media around that one or 2 (hopefully not that many) surfaces before mixing up your Duralay or Pattern resin around the distal/mesial surfaces completely, cover the occl even for stability. Then you use your trusted milling machine to mill into that Duralay with a acrylic milling bur until you reach the stone part of the desired guideplane. Continue till you have the desired 2mm vertical surface, etc and created a resin jig for the DDS to 'perfectly' line up his burs to remove the part of the tooth that extends beyond your planned guideplane.
I am not being sarcastic, but everything is only as good as you can do without creating it in wax on a cast restoration (or milled restoration) for a surveyed crown/retainer.
If your DDS is a prosthodontist who is willing to show you, you might want to ask him/her how he/she want it done . . .
Just my 2 cents' worth.
