That is a very nice gold crown preparation. I was an assistant professor in fixed prosthodontics at USC, and you pretty much matched our ideal standard. Your tooth reduction was conservative, and your actual walls fairly parallel. The only thing I used to do differently was to reduce all four axial walls before reducing the occlusal surfaces. I found it easier to avoid nicking the adjacent tooth during occlusal reduction. Nice work!👍👍👍
I can not describe how happy i am, to see this video listed as a guidance for helping people doing ORE EXAM and to see that this was done by my university and my professor dr tamer hamza!
Dear doc thanks for taking out time to make this video on very basic steps of tooth preparation for the benefit of those at college and just out of it to be able to grasp the essentials, especially for those who get to see mostly the back of the head of the peers standing ahead of them . It's a real refresher for the others .
Thank you for your comment, it really help us to make more videos.
It would be better if you write more information about what bur are you using for each side preparation and the amount of reductions you did
Occlusal surface from functional cusp (1.5mm)
From non functional (1mm)
Used fissure bur
.
.
.
Buccal surface
Use round end tapered fissure bur(chamfer finishing line )
Depth (1mm)
.
.
Lingual surface same buccal surface
.
.
.
Proximal surface
Very thin pointed long tapered diamond bur(long needle)

He used one type bur for cutting which is taper stone with rounded end and for the finish line he used the stone with flat end

It helped me a lot thank you
Mash Allah
Jazakallah for d entire team☺
Jazana wa iyakom
Thank you
Nice demonstration. Preparation looks great. But believe me my friend it's easy to do it on a jaw set with ivorine teeth. The same maneuver is extremely difficult to do intraorally and enamel is not that easy to reduce.
At beginning its difficult however it become easier with time.
Excellent Video!
God bless all of you doctors.
Dr Abdelrahman, It is pride to be my instructor in crown section 2nd year.

Good job doctor. but how to know you've cut the right amount and how to measure occlusal clearance
+Ghada A if I got your question right, we use the periodontal prop
Thank you..,
+Abdelmoaty El Refaie or rubber index .... :)
Depth cuts with a bur of known size/diameter.
Beginner hu SIR...Burs selection ka bhi bta de...plss🙏🏻🙏🏻
Great video, but it would be better that the criteria are explained while the tooth is being prepared.
great demonstration doctor .. i do have few comments or questions that you may kindely answer
1) i noticed that you did the preparation with high speed .. is it better to use it or low speed ?
2) was the distal cusp removed during preparation or should i preserve it ?
thanks my doctor :)
جزاكم الله خيرا
جزانا واياكم ، شكرا جزيلا
water lol.. Anyway good demonstartion none the less :)
how was the finishing and polishing done ?
We work carefully on the sharp lines, line angles, point angles, and transitional lines.
In order for you to have a well-finished and -polished preparation, you have to pay attention to both the parts you finish and round, and to the instruments you use to do so.
Follow a systematic approach in this step (as with all the other steps) to make sure you round and finish every single part of your preparation not missing a sharp line or point.
You can do this using your regular blue-color-coded diamond stone with a slower speed (just a lighter touch on the foot controller). There are some specific polishing kits for finishing and polishing your preparation. Check your local dental suppliers for them.
Got mine today (gold one)
Thanks but I think the occlusal surface is not so clear under bright light.
wich dental bur do you use please?
ممكن نوع stone المستخدمه ومقاس كم
اي نوع Burs
رقمها ..ايه؟
ينفع نستخدم
878_ 012
what is the choice of margin of this preparation? is it shoulder or chamfer? sorry for my bad english
chamfer; it provides appropriate thickness for metal (0.3 to 0.5ml), it's easy to make and it's more conservative than shoulder... shoulder is used with ceramic restoration as it provides thicker finish line and thus more space for porcelain ( porcelain is brittle so requires thicker section(~ 1ml) to withstand forces.
Omar El-Telbany thanks for the information. :)
Lydia Kurnia it depends on what type of crown are you going to do
what's the first\bur ?
c'est quelle fraise s'il vous plait ? conique21?

At beginning its difficult however it become easier with time.

Use half of stone (0.5mm) as thickness of finish line and leave at least 1mm of tooth structure unprepared from the gingival border.
In the buccal (MCR) half of the preparation, you can use flat end tapered stone with a tip diameter (1.0-1.2 mm ) . And for the lingual (full metal) part, you can use tapered stone with round tip and tip diameter ( 0.6-1.0 mm ). You can measure the tip diameter using any measuring devices ( such as a digital caliper ). When using a flat tip stone you can prepare the finish line with the full thickness of the diamond tip, therefore, if you use stone with a tip 1,0 mm in diameter, you can accurately obtain 1,0 mm finishline thickness. On the other hand, if you use a rounded tip stone, you can only prepare the finishline with half the diameter of the tip, thereby, if you want to obtain a finishline (Chamfer) of 0.5 mm, you should use diamond stone with a total diameter of 1,0 mm.
Regarding the distance between the finishline and the gingival margin , you should leave (0.5 - 1,0 mm) coronal to the gingival margin according to the situation. Ofcourse , some situations nessissitate to go below the gingival margin (sub-gingival preparation). you can review this information in any text book.
Thanks, tell the bur sizes please
The bur type is tapered stone with round end, The bur size is # 11 ( o.5 mm ) in diameter at the tip
thx
Azhar CBD I shouldn't have watched this. If I have to get this done now, I'm going to be picturing your demonstration. NUTS.

That’s a minimal reduction at the occlusal.
1. 0mm for the non-functional cusp
1.5 mm for the functional cusp
All you want for this type of restoration
Thank you
😍❤😍
good
Thanks
Overall prep is okay, but wrong bur for facial and lingual reduction should be corse grid tapered torpedo diamond, your prep will lead for enamel lipping..
really? i tend to use a fissure more, instead of diamond. makes it smooth.
there's no set rule on what you can use. Whatever works works.
كبير يا كبير
رائع
شكرا جزيلا
I hear the Azaan
👌👍👍
and now in the phantom dummie head with a cheek mask...thats the real deal!
Patients are the real deal 😊
Heyy Madhura
Loadrite ki cutting 7
Too much reduction for a metal crown.
No, it's the optimal tooth reduction, please go back and review the criteria of tooth prepation mentioned in a several textbooks.
Disliked for no annotations and measurements
Like Those who hate the sound of this machine
No one like the sound of a Turbine
it sounds terrible
To me it sounds perfect
Thank you
this work done by my doc. really I proud of him..
