Maryland Bridge in PMMA

[Francis1901]

I'm trying to make a Maryland bridge on posterior(45- wing, 46- full contour pontic, 47- wing). I'm using an updated version of 3shape and the computer didn't allow me to proceed on scanning. i put the details right in according to what i needed to do. is there any possibilities to make a CAD - CAM Maryland bridge??? anyone who have some idea??

try to make it 3/4 crowns and pontic all bridge, i am not so expert in 3shape but hopefully it will work

i have tried it already. i even use the Veneer, Inlay and Onlay as a selection but it didn't work.

use Frame (non anatomical) coping for wings, ensure all elements are connected as Bridge. really hope this case has retention.

thanks for the idea and the wisdom! i'll try it and hope it works!

I treated the adjacent teeth as crowns and placed the margins around the height of contour. I bulked up the connectors.

After milling , I would remove the pmma until I had the wing design I required complete with cement space.

Ditto's CoolHandLuke. We have done several Maryland bridges using the Frame coping, simple. We did them in metal and used the anatomical pontic with cutback and layered porcelain.

that is one ugly sucker rkm. but nice engineering.

That was before I knew what I was doing.

Is that lava ultimate or PMMA RKM?

Pmma from a few years ago , I posted it in another thread on pmma.

i do this with inlay for the wings,coping pontic and connect it as a bridge
