even scanning a model and milling a crown, i make adjustments to contacts on the model. printing a model to verify contacts seems reasonable, no?I dont care how its made, I just care if its accurate. Dont pee on my leg and tell me its raining.. a printed model, is not as accurate or detailed as a stone model with pvs. That doesnt mean its not usable, its certainly detailed enough to work on, but if youre designing from a scan anyway, I dont see the point.. check your contacts and occlusion on a printed model? Why? Because the scan isnt accurate enough? Ive looked at enough dies under the scope to know that youre not going to get that detail in a printed model.. So whats new? Everyone has their shortcuts, doesnt make it better.
thats cool, until the standard pvs market dried up due to i/o camsyou know what would be cool?
imagine instead of pouring impressions or filling impressions with plaster/stone/resin/polydie you spraycoat the impression like a truck bed liner.
you'd get a skin instead of a solid. might be nifty.
to acheive this maybe fill a spray gun with resin and ash/fiber filler. spray on, let dry, pop out.
then how are people doing it effectively?Very reasonable, I kinda wanted someone else to admit that going model-less doesnt seem like a good idea... You cant judge path of insertion, or the software cant usually, in CAD..
i wouldnt hold cerec to commercial lab standards in any way shape or form. lets ignore their crap. there are still labs doing it. and being profitable is the goal. thats why we are in business. making teeth is secondary.Im not saying its impossible. Cerec Drs do it everyday apparently. One mans success is another mans remake. Thank God we dont all use the same definitions.
how can you be successful at closing margins with microscopic integrity, when you dont have the ability to do that without a model? .
Building a digital lab is a totally different beast than an analog lab. The problem with most dental labs trying to get into digital dentistry is that they think they can pull someone off the street and teach them how to design a crown in a couple of hours and then they are shocked when things start to go south on them. Also they have a porcelain tech grind, stain and glaze the crowns, thus negating the benefit of going digital. A weekend warrior tech is the Achilles heal of digital dentistry. Yeah they can design crowns, but you are going to be doing a LOT of finish work. I have worked in several places and trained under some very good technicians (both digital and analog) and have just celebrated the first anniversary of my own dental lab.then how are people doing it effectively?
actual question, not just trying to be an ass...there are labs doing it. and labs here on DLN. successfully.
If youre not fearful of technology and what it can do, you arent paying attention. Answer this: if technology eliminates your career, is it beneficial to you?It sounds like you might be a little fearful of technology and what it can do.
Cousin of mine became a daddy that way at the city 4th of july celebration.You got that backwards, go grab the chick then hit the portables.
If only he had been taught a mans guide to womenCousin of mine became a daddy that way at the city 4th of july celebration.
No offense, but get your eyes checked or raise your standards. I too do 95% of my work with Katana, but every one needs some tweeking with stain. Biggest problem is, two crowns from the same puck can have different color/value. Theyre good, but there not perfect.I use Katana Zirconia so for 95% of cases I don't have to worry about staining them. The only problem with that is that you need a large stock of zirconia on hand.
this kind of info is the stuff i need. theres no way im trying to pull a noob off the street and teach them how to churn out crappy crowns. i have little to no adjustments on my milled crowns (single to 3unit bridges). green state or post-sinter. there shouldnt be much if any adjustment needed. so that said, i dont buy all those green state tools you do. i use TD tools for milling and get significantly more units per tool for a fraction of the cost. thats not to say sierra tools are bad, they are not. TD tools are just as good if not better and are $100 less expensive lol. thats a no brainer. havent gotten to printing a model yet, but i am right on the cusp of pulling the trigger on some sort of system. the labor and time involved with creating an analog model, sectioning, and ditching, is just far too much. may start moving toward scanning impressions in the mean time and only pouring check models for contacts.Building a digital lab is a totally different beast than an analog lab.

I work solo and so I don't have the time for failures. I am able to easily scan, design, finish and glaze 10-12 crowns a day. The trick is that you have to print models and mill your own crowns. Also I use Katana Zirconia so for 95% of cases I don't have to worry about staining them. The only problem with that is that you need a large stock of zirconia on hand. I get on average 23 units per disc. I have doctors comment on how they look better than the emax crowns they used to get from their other labs. Waxing and pressing Emax used to be my forte. No more!
I buy Sierra Tools for my mill and only buy diamond. The burrs are $145 each but the last time I switched them out I had done over 900 crowns on the set, making the cost per unit on burrs to be around 35 cents. Printing models to check the contacts is also something I do and I have gotten the resin cost per model down to $.50. I do about 95% of my finish work while the zirconia is it's green state using Matrix Shapers I get from Henry Schein. Those are AWESOME, I trim sprues and thin margins. Just don't buy the green and white ones. They are green and I think a medium grit. The green and white ones include a fine white tip to them and they each cost as much as 5 of the green burs (around $35) and I have not found any benefit in using the fine tool on my crowns.
I am fully digital and lower my cost to dentists while still maintaining a good profit margin. I did a full lab costing for my business and have added the price of everything into my crowns down to the garbage bag that I replace every other week. I am able to have a significantly lower price than other labs in the area and still maintain a good profit. I also have a 3 day turnaround on my crowns which is very attractive to dentists. I could easily triple my output if I could find another tech who is trained well in digital design.
yall are sick hitting on the cute chicks in the portapotty. gross!You got that backwards, go grab the chick then hit the portables.
perfect doesnt exist in what we do. and while you, and me, and @Affinity strive for it in our work....its unreasonable and unobtainable. perfection is imperfect in what we do. want proof, go grab a "rule" book of tooth morphology and start looking at teeth in nature. perfection is imperfect. i started getting far better results when i accepted that fact.No offense, but get your eyes checked or raise your standards. I too do 95% of my work with Katana, but every one needs some tweeking with stain. Biggest problem is, two crowns from the same puck can have different color/value. Theyre good, but there not perfect.
