Dexis Digital X-Ray: Should I Make the Transition?

November 19, 2008

Dr. K. asks:
x-ray_img.gif
I am computer illiterate. I am in my sixties and am such a dinosaur about digital products that I shudder at the thought of having to bring even more high-tech into my practice. I am looking at digital x-ray systems now. I know nothing about the high-tech aspects of the different systems. I am considering buying the Dexis Digital X-Ray System. The system is supposed to be user-friendly and they are supposed to have a lot of tech-support. I am looking for feedback from people in my position that have installed these digital x-ray systems in their practice. What has been your experience? Should I make the transition?

PhysioStar NFC: Better than Conventional Acrylic Dentures?

November 19, 2008

Dr. O. asks:

PhysioStar NFC has recently come out with a new kind of denture tooth made partly out of polyethyl methacrylate (PMMA) and composite. The cervical half the denture tooth will bond well to acrylic denture base materials because of the polyethyl methacrylate. The coronal half of the tooth is made up of two layers of NanoFilled composite. These teeth are designed for lingualized contact occlusion. Has anybody tried these? What was your experience like? Are these that much better than conventional acrylic denture teeth?

Editor’s Note: According to Candulor, the manufacturer,

“With the new anterior tooth line, we didn’t want to create denture teeth but teeth
which come as close as possible to the real thing…

Up to now, the usual practice in the dental market has been to use 1–3 different layering schemes per tooth line. For the PhysioStar® anterior tooth line, Candulor has developed and patented a special layering pattern for each mould which is typical of the tooth, just as we find in nature. Bright interdental flanks avoid shadows in the areas between the teeth.

To enable bonding with the denture base, half of the tooth body is made of PMMA material.
PhysioStar® NFC is a 4-layer tooth. Two of these layers are made of NanoFilledComposite (NFC), which ensures the particular, abrasion-resistant characteristics. The other two layers are formed from PMMA material, which provides good bonding with the denture base acrylic. The layering of enamel and dentin has been specially selected to ensure that the chromaticity of the teeth is retained after grinding.
