"Awesome work. I have been doing CAD-CAM dentistry myself for a few years and couldn't imagine not doing it now. It will take a long time for dentists to adopt it, for some reason, but I can't wait to see what happens when critical mass I reached!"
"Don, Thank you for your comments. While those E4D clinical examples were from earlier this year my skills have developed. Just yesterday I was able to perform single visit Empress CAD restorations on teeth 7,8,9,10 in just 4.5 hours. Prepared,…"
"That's great! I am doing eMax single units in 1 appointment of about 1:20, from start to finish. And it "all depends" on multiple units. Tuesday I completed 3 eMax in under 2 hours, #12-14. Also, because I am using a "punch" approach to most…"
"After having received training in Botox and dermal fillers I was disappointed to find out from the MA. Dental Society that only educationally trained specialists in oral surgery are recognized by our state and able to acquire malpractice insurance."
"Julian, Thank you for your comments on this topic. Just to clarify: it will be a long time before any of us will discontinue our usage of elastomeric impression systems. I often use them in conjunction with the E4D system when the digitally scanned…"
"Giovanni, Thank you. The beauty of the chairside E4D cad cam digital technology is that often you can avoid the sometimes messy and always unpleasant elastomeric impression. I am still learning with each procedure but know that soon the elimination…"
"Nice cases Jim.
I presume you are are scanning vs. taking impression as well.
The patients must love not having all that goop in their mouths.
You should present your work at one of our study club meetings."
"Do you know about the 4th CAD/CAM & Computerized Dentistry Int'l Conference in Dubai 13-14 May 2010?Two hours Open Discussion Forum "Zirconia - The Truth"will put on the stage resurchers, clinicians and manifacturers to answer all your questions."
"I agree with Jim. It isn't a matter of if but when. However that when is not here yet, in my opinion. On the data capturing side, even though the technology is quite remarkable, I can not use it in 100% of my cases so I am not willing to invest and…"
"Giovanni, The history behind your concern is important. The early Branemark studies on biomechanics by Rangert et al indicated that abument screw loosening was simply due to mechanical overload. This load was either from excessive occlusal forces or…"
"Cary, This is a great service for those patient's demanding an immediate implant supported fixed bridge prosthesis. While it is "simple" in expert hands like yours and Giovanni's , there are many diagnostic considerations. Some of these are the…"
"I agree in concept with your comments but the reality in daily practice is different. As a user of the E4D digital scanner and CAD/CAM milling machine for single unit milled ceramic restorations the traditional relationship with the dental…"
The one concern I have with the All-on-4 is the fact that the fixed prosthesis is secured to the angled correcting (stock) abutments on the fixtures, via small retaining screws similar to the ones used for prostheses attached to stock abutments 20+ years ago. They were known to loosen and fracture. One of the reasons custom abutments came into being. This may result in problems we would like to avoid in the first place.
