ONE-WING MARYLAND BRIDGE - WITH TWO WINGS......
This is a very interesting case from cerecdoctors.com Mentor Mikkel Buchgreitz.
Hi One-wing Maryland bridge fangroup!
Here is a trick when cementing one-wing Maryland bridges.
Can be difficult because they like to rotate around the abutment tooth when lightcuring.
Design the bridge with a small antirotation wing, and remove it after cementation.

Hope this can help.
Maryland bridges with CERECÂ is really a nice tool as a final restauration and as a provisional when doing implants.

Thanks for the tip! Going to try adding this antirotational 'wing' for an implant temp this Saturday!
That is a great idea I like it. Â Obviously easier to remove if using enamic or other resin ceramic hybrid. Â With emax as a temp its a little more difficult but still doable. Â Great tip.Â

So assuming a patient with good hygiene and low caries risk, why take off that small extension? Floss will slip under, and with a bit of fluoride varnish applied at recall visits the risk of it decaying under the non-attached wing should be minimal.
Gary because as soon as the patient functions the teeth will move and hit the little wing cause to much torque on the other wing and result in a deboned.
If you bond it you have the same problem. Two wing Maryland bridges have a much higher debond rate.
I would agree except that on an upper tooth the occlusal forces push the lateral labially or apically, away from any torqueing of the other wing. I agree that having two wings *attached* have a higher rate of debonds because of the independent movement of the abutment teeth. But virtually all of the old style 2-wing bridges I have seen over the years only debond on one wing, and then stay bonded on the remaining side quite well. I think once the bond gets broken on the weakest side the stress from that movement is minimal. The problem with the half debond is that the bigger, non-attached wing becomes a food trap.
Awesome result and beautiful contours! I like the documentation too. The staining looks good. Guessing you used sunset instead of the body 1 shade?? That's the only nit picky thing I would say. Maybe use a more brown shade instead of yellow to match... Cameras are tough and guessing the patient would never notice. Love the craze line in it! This is a really nice case and not one that a lot of docs would think to do as a permanent restoration. Good work!
