FCZ adjustment in the mouth

[Martin Bubez]

Hi guys,

Can anyone recommend a high speed bur for dentists to adjust full zirconia in the mouth?
Our guys are using diamond burs and it causes heat which in turn can cause zirconia to crack.

Answers on a postcard please

Thanks

Say what...HS for adjusting occlusion?? How about slow and low with water, and HS for cutting them off?

i never advise high speed adjustments on zirconia. everything should be low speed under water. guarantee waived otherwise.

You guys dont use high speeds on zirconia? If it has water spray whats the problem? I use red-striper diamonds they work awesome and last a long time. Also flexi diamond disks are the money, a must for contacts.

I don't after it's sintered. If I need to touch up, I use HP inverted diamond cones or IC5/9s etc at a slow speed with water.
Maybe I'm just paranoid?

But remember, this thread is about Dr's adjusting in the mouth, and do you think they're
as careful as us in how aggressive they are, and in following up in taking the micro cracks
out with a HP at slow speed. HS will only polish the surface when they "polish" it, cp to
slow torque of a HP that will better get smoothed surface past the micro cracks. I don't
want to depend on zi being "self healing".

A.... I use SI-47 HS on zirc anatomy, living on the edge! It's the clinician aggressively adjusting that's the problem.
Have some red-striper HP also. Work great !

Does anyone really think Drs 'take care' of crowns?

Exactly, so why would we want to promote for the Dr's to grip it and rip it, with a HS Diamond,
unless they're willing to take the next steps in correctly polishing it?
