Replacing Crowns on Teeth #7-10 With BruxZir® Anterior


okay so let's go over the case of the

week for this week and I want to present

a case that was actually completed by

dr. Anna Maria Mears on she is one of

our in-house dentists and she's also a

certified dental technician so an

extremely talented individual and this

case this patient presented for the need

to have for anterior crowns replaced a

seven through ten so dr. Mears and after

getting the patient numb went ahead and

removed the old crowns and now she's

prepping the margins and making sure

that any recurrent decay is cleaned up

from around the margins of these teeth

obviously you want to go through and

make sure that you clean everything up

after removal of the old crowns and

certainly there was some leakage around

these where they had to be removed this

technique in terms of the crown

preparation is the reverse technique I

like it because it gives you a set of

birds to go through in order to get a

final prep it gives you certain

guidelines so it's very helpful

clinicians have their own technique and

obviously if you're comfortable with the

way you're prepping teeth and you're

doing it right that's based on your

comfort level so again the reverse prep

technique works quite well and we like

it because it's a standardized way of

prepping the teeth so once the teeth are

prepared the laboratory actually has

fabricated a tooth prep guide that you

can seat on top of the preps to make

sure that you have enough reduction now

for the topic of our discussion we're

talking about Brookes interior and

because it's a brookster we can have

minimal reduction in order to fabricate

these crowns you want to go ahead and

check the bite and like I said before

the reduction guide is seated on top of

the teeth to make sure that you do have

enough reduction one little trick is

that you can always place a

through now the different areas of the

reduction guide and using your

periodontal probe you can check to see

how much reduction you have through the

actual reduction guide so once we know

we have enough reduction we can go ahead

and realign our bio temps and the

patient can actually go home with a set

of temporaries when the patient comes

back to have the final impression visit

if you don't do it at the same day of

the prep that bio temps are removed what

I like to use on what dr. Mears on use

in this video is ultrasonic to get rid

of the temporary cement it's very

helpful so you don't have to scrape away

at the temporary cement and then the

cod2 core technique is utilized so that

we can go ahead and capture the margins

so once the first chord is placed we'll

go ahead and refine our margins and make

sure that we have nice clean visible

margins and then the second chord is

placed along with some cotton rolls or

copper caps I really like using these

comp recaps because the the pressure on

the tissue helps the retraction and also

helps with the hemostasis around those

teeth so after a period of three to four

minutes we can go ahead and remove that

second cord that was placed and inject

the Lightbody and and the medium body or

actually in this scenario this is medium

body capture material along with heavy

body capture and pressure material so

once the impression material is set we

can go ahead and remove the impression

tray from the patient's mouth and we can

visualize the the margins that are

captured within the impression and

utilizing a triple tray I believe this

is a clinicians choice triple tray and I

like these because they're very rigid

you can go ahead and capture the area

where you want to impress one important

aspect of the Brooks or anterior is that

there is a bit of translucency in this

restoration and it's very important to

capture the stump shade and relay that

information to the dental technician so

that they know what they're working with

underneath the the final restoration so

once the sump shade is selected the

information is sent to the laboratory

and a technician can design and produce

the brucks from an interior restoration

and as you can see here they are very

well integrated into the patient's mouth

so I'm very excited about this product

it's a very good product and it brings a

little more translucency to the original

brookster line of restorations and I

hope that you get a chance to use it in

the near future
