In this article, the Healthsoothe team provides 25 crown prep tray set-up. These are the tools used during the procedure.
There are lots of sorts of crowns which may be utilized, such as ceramic, porcelain, resin, and stainless steel (cosmetic crowns are usually made from ceramic or porcelain). Before I list crown prep tray set-up, let’s take a look at steps to posterior crown prep.
9 Steps to Posterior Crown Prep
First of all, you need to think about the materials your crown we are made of. Can it be layered or monolithic? Gold, PFM, e.max or zirconia?
Why should you consider this first? Since each material demands different decrease quantities and prep design — and you need to decide which will make it possible for you to achieve or surpass your individual’s patient closing desirable end result.
As soon as you’ve determined what’s best for your individual patient and their scenario, where do you begin?
- Eliminate outdated restorative material and rust to confirm restorability in its existing state and demand for potential root canal treatment or crown lengthening. In addition, I decide whether a crown restoration will be the most conservative and most lasting or will the tooth and individual patient be better served when performing an inlay or onlay restoration?
- Isolate the tooth for appropriate bonding and glue protocol to put the build-up materials of choice (personally, I enjoy light-cured resin or double cured resin in regions that light penetration might be challenging. Make sure your build-up materials and bonding agent are compatible). Do not overbuild the tooth because this waste substance but can also impact the ease of the following step.
- Today we’ve prepared for the crown prep (when a tooth will surely require a crown, e.g. root canal posterior molar with big filling, then I will start with this measure ). First thing: I begin with deep cuts onto the occlusal table using a known length bur (you will find particular depth-cutting burs too) that for the desired decrease of the restoration of choice. I take this bur down the central groove, across the cusps and out the grooves to depth. Now, there’s absolutely no confusion about just how much to remove.
- I shall then put a tiny diameter bur (KS0 is my bur of option ) to eliminate the bits of tooth which are glued up between the depth cuts. I basically set the bur from the groove and push or pull, which cuts or”amputates” which segment of the tooth off rather quickly and efficiently.
- I shall then take the identical bur on the facial and do thickness cuts two planes: at the incisal 1/3 then to an approximate region of perimeter area across the gingival height. This bur is 1mm in diameter, so adjust as needed for material choice. Make sure your accounts for facial/lingual region in which you want added thickness to your functional cuspal location.
- Put the bur back into the thickness cuts and pull/push again to eliminate the sections of tooth remaining depth cuts quickly. It’s more effective to cut these parts away vs. milling the tooth back and forth at this phase. When the enamel is decreased, then you can readily smooth and refine the margins.
- Take the bur carefully involving the interproximal regions to break contact and stick to the gingival contours and/or restorative material.
- Complete the margins with this particular bur and rounded off any important edges or ledges.
- Switch into a bigger, finer diamond bur to enhance and smooth margins and preparation overall.
- Done. It is very important to know how to set up your instruments. CROWN PREP TRAY SET-UP

What should I expect at my crown prep appointments?
- To begin with, the dental assistant is going to take a mold of your tooth before any work is completed. This mold will allow your temporary crown to be produced. If the tooth is broken, then do not worry! We’ve got pre-made crowns available, but the dental assistant can definitely work a little magic to make a great temporary crown if the tooth is broken. The assistant will take this opportunity to assess your medical history, the treatment program and have a blood pressure reading until the physician comes in. The doctor will get that tooth numb, just like they do for fillings.
- Then, the physician will trim the surface and sides of your tooth to allow sufficient space for the laboratory to make a crown to fit correctly within your current tooth. Based on why your enamel requires the crown, the physician might have to perform what’s referred to as a build-up. This implies material has been inserted into the tooth to get enough good arrangement for the crown to be cemented on. Following the doctor is pleased with the form of the tooth, he’ll put some exceptional cable just beneath the gum line. You will feel some pressure while the cable has been put, but this guarantees a fantastic impression for the laboratory and will be eliminated after the impression is completed.
- The impression is ready next. This is what the dental lab needs to make the custom-fit crown for your mouth. Thankfully we can utilize our scanner to take these impressions digitally and send the scans directly to the lab. Now the dentist is done! The dental assistant will take over and create your temporary crown and also discuss any necessary after-care instructions.
When you come back for the permanent crown, it’s ordinarily a much briefer appointment. On top of that, rarely does the physician need to numb tooth up! The assistant will remove the temporary crown and try in the permanent crown. The health care provider will check it on making certain the match is ideal before cementing it into position. The doctor recommends that you should not drink or eat for 1 hour after your appointment, but you’re great to use it just like a normal tooth!
