My frames are designed from a full contour cutback.
For us we are doing less and less copings... full contour or full contour with backup... are the big majority of our work... We tried to work it that way with the multi plate i mean when we use to make more copings but the thing is that it has to be simple copings with no need for support for the ceramic... also when we had tight occluion in anteriors we had to put a high lingual zirconia band we had no choice but to scan the whole situation... that doesnt leave you alot of cases that you can do this way..As much as I prefer 3Shape I have to disagree. If your main workflow is single units (frameworks not full contour),then DW is so much better in this area.
Sure I wouldn't mind. First reason: DW multi die plate is simply better design then on 3Shape, calibration and cleaning is much easier with DW than with 3Shape because DW doesnt have multi die arm, just a plate. Second and more important reason: in DW you can start designing your first coping as soon as first die scan is finished, no need to wait for rest of the units on the plate to scan, where in 3Shape you have to wait for all 6 units to scan. Also if I remember correctly you can now use 12 unit plate with DW3, so you can scan double the amount in one go. 3Shape is superior to DW in many ways but not in multi die scanning.Would you mind describing more specifically how you see DW as preferable for this application. I (we) can design a great framework in 3Shape in about 2-3 minutes a unit.
thanks
I agree 100%, as I mentioned before it is only multi die scanning where DW3 shines. Designing multi unit, full contour and implant cases is much better and easier on 3Shape. We are comparing 2 scanners here and it is only fair to mention all advantages and disadvantages of both, regardless personal preference.For us we are doing less and less copings... full contour or full contour with backup... are the big majority of our work...

From our point of view the way things are going forward its not a thing that would be used alot..
on the other hand the advantages that 3shape offer are stuff that would be needed.
We work with dental wings for a long time and we liked it at some point but it seems that its not folowing the evolution that is happening in the way laboratories are working...
while that works and i won't knock it, its not necessary for every single frame. unless you need full contour lingual, or are making metal contacts, or some strange thing, full anatomical cutback isnt that necessary.
but Luke, you ask, how do you gauge distance and cusp heights?
is very simple. use the morphing tool. the circle is a diameter of 3 mm. pull the edges of the coping to where you have just over 1 radius of the circle in clearance.
no mucking about with pointy cusps, no messing around with runny opaquer. best of all no need to retrim. create easy mushroomoid shapes in 50 fewer clicks.
Good luck with the free trial- let us know if you find one.
I have a version of DW ($traumann). Buggy as compost pile. Swapping files from a DW scan to Exo crossed my mind as well, but remember you will have to work out parameter bugs when they crop up. Truly the best thing they have going is the multi die scan. Anyone know if the 3shape 900 series does it?
