Ive done one lower anterior job. Similar to this. I warned the dentist and he told me to build it out with thick wings. The patient is aware. That was 6 months ago and i saw it last week as i altered his full upper denture. Depends on the room you have to play with. My eyes are telling me no, or at least warn the dentist it will have zero warranty.
Like bumfrey, I have done a couple on loweer anteriors. both with the same client both times I said they are contraindicated, blah blah blah. Still in the mouth as far as I know. this is a couple of years ago now.
I like the design RKM showed. I cannot see that breaking . But are 2 wings better than 1 ??
I have one in my mouth on the lower insicor. Single wing on each side. It's been about 10 years I think. Only this last year, one wing has separated. I remember making it and the joins were kind of thin and I was thinking to thicken it up. It's still functional and flossing is a lot easier now with a single sided cantelivered Maryland.
Exam flexes with the teeth without debonding during mastication. When I had metal Maryland bridges I was going back to dentist to get recemented frequently. Ten years in with emax bridges and not one time have they popped off. I am terrible about chewing my nails which is problematic with Both laterals congenitally missing. Zirconia may be hard but it offers no give like emax.
Emax can be bonded to teeth, zirconia can not. Same problematic popping off will occur with zirconia as with metal. Yes I realize zircon is actually a metal, so is lithium.
I’ve never understood what people are eating that they need something harder than their natural dentition.
My argument is only for pressed emax, not milled as the molecular structure differs between the two.
As for the one wing versus two wing discussion. My opinion is if the preps are liberal go with two wings. If the peeps are conservative go with one wing. Why? The more material thickness there is will allow for the material to flex without fracturing while both sides are bonded.
single wing would have been a better idea. natural teeth are mobile and with little to no contact between 8/9 and 11/12 theres bound to be movement at some point. even if just during mastication. first thing to give will be the cement....or the wing itself additionally, looks like some significant incisal edge wear and down along the ligual marginal ridges. careful since thats where youre putting the wing!
What I have done, a couple times now, is one winged e.max "Maryland" restorations. Not an option for the OP, anymore, but flying a lateral incisor from a central, especially on the lower arch and with enough wing 'thickness', has worked well in the past.
