I'm considering purchasing a 3 shape scanner soon. I've been evaluating various workflows and was wondering...See more how many different ways current users are putting the scans to work. Such as; anyone splitting the files for SLM copings or zirconia coping with milled or printed wax ups for press-to restorations? Milled gold crowns with Strategic Milling? Any good or bad experiences with CAP or CMC? I've been milling in house with in-lab and have decided not to pursue another milling machine at this time. So I'm looking to partner with others to provide the mills. Thanks. — tagged 4 users
Our 2008 Digital Technology survey found that CAD/CAM-milled restorations made up 19% of respondents'...See more C&B workloads. We asked respondents to predict what their CAD/CAM caseload would look like by 2013, and they predicted it would more than double in those five years, rising to 42%.
So how did their predictions pan out? According to LMT's 2013 Digital Technology survey, CAD/CAM-milled restorations made up 41% of their C&B caseloads! Pretty spot on!
For more statistics on the growth of CAD/CAM, watch for our May issue.
When the controversy over the possibility of lead in PFM restorations arose in 2008, the ADA conducted...See more an independent study to determine the degree to which lead may be present in crowns. In 2009, it released the results of this study, which found only trace amounts of the naturally occurring element in 44 different porcelain powders and 102 finished porcelain-metal crowns produced by domestic and foreign dental laboratories. The results ranged from below detectable to 113 parts per million (ppm) in the 44 porcelain powders, and an average of 46ppm in the crowns.
"Based on all the information to date, both from our own testing as well as reports of other analyses, we are confident that no measurable levels of lead are released from dental crowns made from dental porcelain typical of available sources," said Clifton Carey, PhD, administrative director, ADA's Paffenbarger Research Center (PRC), which conducted the study with the ADA's Division of Science laboratory.

New DOCERAM Product Line: Teeth like Pearls - Tuesday, November 05, 2013
The trend towards monolithic...See more restorations made from full zirconia is unbroken.
As one of the pioneers of dental CAD / CAM, DOCERAM Medical Ceramics sets a further milestone: pre-colored zirconia in dentine shades: NACERA Pearl.
This dentine shade pre-colored blanks made from zirconia ease the technician's job significantly for preparation of full-contour restorations, the manual work is reduced to a minimum.
The complete elimination is possible within the molar area.
This was achieved by the new PCR-color concept that allows a completely free choice of colors in the range of dentin shades.
New colors are available within the entire spectrum of the VITA© Classic colors, also in the area of previously impossible VITA C and D colors.
Dan O' Rourke put out a challenge to our industry and the LMT editorial team and I are intrigued by his...See more suggestion for a "Man vs. Machine" challenge and are discussing its possibilities. At present we're somewhat stuck on the logistics and would love to invite input from others in the community. Since there's a ready-made CAD/CAM group, we will post the idea for a challenge in that group. Please join us in inviting dialogue that would help us form a plan of action.
One thing that strikes us with regard to the "which is better" question, are the comments from Don Cornell, printed in our April LAB DAY coverage:
Automation and the 25-30% market contraction caused by the recession are helping to fuel what Cornell calls a move toward "good enough" dentistry for posterior restorations which is, in turn, driving the growth of full contour restorations. "Full contour is not just about something that's cheap-it's good enough in this application, in this space, at this price point. It's shaped like a tooth, it blends in and margins are good. When it comes to full contour, there are those labs that don't want to participate. They say "that's not who I am," but can you really afford not to participate?"
This concept of "good enough" is one to be reckoned with IF the integrity of the patient's restoration and oral health are not comprised.
For everyone who offers suggestions, please keep in mind LMT's necessarily unbiased role as "information disseminators" which means we need to be sure, as non-technical facilitators, that we aren't condemning any restorative option. — tagged Dan O'Rourke, CDT and Milling

Just participated in a digital forum at Whip Mix where Dr. Russell Giordano discussed the material science...See more and dynamics of Zirconia and Zirconia layering ceramics.... lots of "i's" and "t's" to dot and cross if you really want to ensure a scientifically sound interface between your Zr substrate and the Zr core... one thing he advocated in particular, and I know we have heard different variations on this from a variety of Zr and Zr layering mfg.s, but he stated quite emphatically, that anytime one introduces stress (grinding and/or finishing of Zr frames and full-contour Zr restorations) that a 'conditioning firing' is imperative! This conditioning firing consists of running the Zr frame up to 1000 C and holding it for a minimum of 15-20 mins., then a slow cool coming down- not 1-2 mins., but a REAL slow cool down to a min. temp of 600 C... then bench cool down to room temp. If one doesn't observe this conditioning cycle, the Zr will remain in a Monoclinic 'stressed' state and not return to a tetragonal/metastable state! That is to say, if a crack starts to propagate, it will not necessarily force the crack together, thus stopping it or encapsulating it. What this could spell for us is short-term, false-sensed "success..." OR LONGTERM Failure, depending upon one's mindset... Noritake & Vita were proponents of this necessary cycle long before others joined the band wagon... — tagged Whip Mix Corp.

I'm not...See more a big fan of these kind of restorations, but OK, I took the case and send it to the milling lab for a full Zirconia bridge. Turns out that the computer program doesnt know how to scan multible connected units. LOL. I got the case back and I constructed a PFM overlay bridge in NP. It looked great and I saved myself about $ 300. plus felt great that human craftmanship still counts for something :0)

Interesting facts to think about. 30 years ago, all the porcelain manufactures began to think about how...See more to make porcelain powders which through a complicated and sophisticated build up technique would make it possible for the dental technician to create natural looking teeth. Twenty years later they began leaving out Opacious Dentin, then they began to manufacture a two powder build up, and today we are approached with the One powder "Do it all" porcelain. (Just add stains!). Personally I see a slow curve of downgrading the technical skills of the educated ceramist. It is truly a shame that we have come down to this. The artistry and sophistication of our work seem not to matter anymore. I bless the dentist who in spite of the trends in our industry still wants life like restorations and are willing to pay for it. Art which we as technicians have been educated to create doesn't come cheap, but the dentist gets what they pay for. — tagged Porcelain
This is just me venting.. (in hopes of gaining manufacturers attention). It really frustrates me to know...See more that all major implant companies and non associated milling centers are heavily advertising "Custom Abutments". We do 100% percent of our implant restorations using custom made prosthesis, with 90% of them being screw retained. What irritates me is that when I design my custom screw retained abutment and scan or send it out to be scan (depending on the implant), I sometimes get a message from the manufacturer saying unable to mill due to "milling limitations", "insufficient block size", "restoration does not fit within our milling parameters". Again Most implant companies are pushing custom made abutments and more so screw retained crowns. So why not make your milling blocks BIGGER?
I wouldn't probably get an explanation other that "We're working on it"...... — tagged Abutments

I think the solution to our changing laboratory world is to reinvent ourself as Marta Lizza so eloquently...See more put it in a post to me. I have taken her advice seriously and done two things. I have re kindled my interest in the I.C.O.I. Implant symposium program and I am taking training to mill my own Zirconia restorations manually. I have done a lot of re thinking on the Emax restorations and I am now playing a lot with layering the material. Love it!. I refuse to go on retirement as a bitter old man and chose to go out with fireworks when that time comes. :0)
I have been a lab technician for over 35 years now. Was educated in Denmark and made my career here in...See more the United States. I have always loved my work and still enjoy my days in my laboratory. However, lately I find myself being somewhat bored as my clients more and more go for full Zirconia Cad Cam or eMax restorations.

Does anyone feel the same way or is it just this old dinosaur sitting reminiscing :0) ???????

I know cad cam and milling are...See more the proposed substructures of the future, but I'd love to know how many labs out there are still filling the demand for alloy based restorations.
