dealers. It’s a universal prep technique<br />

that works for all materials, although<br />

as the next letter in this section points<br />

out, the strength of BruxZir ® Solid<br />

Zirconia is starting to change how<br />

much we have to reduce, especially at<br />

the margin.<br />

– Mike<br />

Dear Dr. DiTolla,<br />

First, thank you very much for your<br />

educational support and updated dental<br />

market information. The latest issue of<br />

<strong>Chairside</strong> (Vol. 7, Issue 1) includes your<br />

very interesting and helpful article “BruxZir ®<br />

Solid Zirconia Anterior Esthetic Challenge.”<br />

I would appreciate it if you could give me<br />

information about labial and palatal crown<br />

thickness (Figs. 31–34). I wonder why you<br />

used a shoulder preparation technique<br />

when the BruxZir website says that feather<br />

edge is acceptable?<br />

Cordially,<br />

– Alex Zavyalov, DDS<br />

New York, N.Y.<br />

Dear Alex,<br />

Good question! I guess the best<br />

answer is that having spent the last<br />

20 years prepping all-ceramic crown<br />

preps at a certain thickness, old habits<br />

die hard. My Reverse Preparation<br />

Technique uses a round bur to ensure<br />

that I get 1 mm of reduction in the<br />

gingival third to help the esthetics and<br />

the emergence profile. As you pointed<br />

out, BruxZir ® Solid Zirconia is the<br />

one monolithic material (besides cast<br />

gold) that can handle a feather-edge<br />

margin, and we are just getting started<br />

with a Minimal Prep Crown Project to<br />

see just how little we can reduce an<br />

anterior tooth and still have a decentlooking<br />

BruxZir crown. Imagine if we<br />

could prep a tooth and stay within the<br />

enamel, yet be able to cement a highstrength<br />

all-ceramic crown, rather<br />

than bonding a veneer. So, yes, even<br />

though I did not prep conservative<br />

margins on those teeth, you certainly<br />

can prep those types of margins with<br />

BruxZir crowns. Even if you were<br />

worried about esthetics on the facial,<br />

you could still prep a conservative<br />

margin on the lingual.<br />

Dear Dr. DiTolla,<br />

Regarding Dr. Ellis Neiburger’s article<br />

in the last issue of <strong>Chairside</strong>, “Is It Time<br />

to Do Routine Adult Pulpotomies?”<br />

(Vol. 7, Issue 1), there should have been<br />

more discussion about using lasers to sterilize<br />

the pulp instead of formocresol, and<br />

other options instead of IRM, like MTA.<br />

– Brian Danielsson, DDS<br />

Ridgecrest, Calif.<br />

Response from Dr. Neiburger:<br />

Dear Brian,<br />

The article focused on time-tested<br />

pulpotomy techniques that, in light of<br />

the world’s poor economic situation,<br />

can be done easily, quickly and<br />

inexpensively. Laser sterilization of<br />

the pulp chamber is relatively new,<br />

has only a small amount of research<br />

to establish efficacy and requires laser<br />

equipment more costly than a $10<br />

bottle of formocresol. It holds promise<br />

and should be further investigated.<br />
