Crowns made of metal and ceramic are also referred to as "Porcelain Fused to Metal" (PFM) crowns. Additional reduction is required where porcelain is required to provide room for both metal and ceramic. The permanent teeth between your canine teeth, or cuspids, in the front of your mouth and your molars in the back of your mouth are called premolars, also known as bicuspids. In this video, Dr. Richard Stevenson demonstrates about PFM Premolar T-PREP - a different way to approach reduction. Works well, even without prep guides or stents.

Great video, as always! Maybe some time in the future you can do some tips and tricks videos on clinical scenarios we often face that stray from clinically ideal. Some potential examples... Deep sub gingival decay in the proximal box that makes getting a good seal with your matrix band very difficult. Adjacent class 2 restorations - the best way to restore to get good contours and contacts. Working on the distal most tooth in the arch when you have a rubber dam on, and the clamp is in the way of your matrix or operative field. I’ll try to think of more!

This is such a small video with one simple preparation of a tooth, but make no mistake, this is truly a pillar for dentistry. It's free, very effective in its teaching, all high-yield information and shows every step you need to take and why. If you are a university teacher reading this please, PLEASE look into this video and remember yourself why you teach. If you refuse to simplify or show all the steps and why we do it, it's not only the students that pay the price, it's also the patients they have in the future. People teach to make the world better. It shocks me how bad some professors were in my dental school. Bad teachers shouldn't teach. Dental schools are full of them.

Thank you for sharing this technique doctor. If we are doing a PFM on tooth number 5, do we still make 1.5-2 mm occlusal reduction because there is some pre-existing clearance before we attempt occlusal reduction especially in Columbia typodont. I end up with lot of clearance . Please try to make a video on it doctor. That would help us immensely. Thanks..

@StevensonDentalSolutions 5 жыл бұрын

Good question. If the final restoration will be identical in contour and occlusion to the pre-op, then perform the procedure with the T-prep design, and you'll be in good shape. However, if the graders are looking for the amount of clearance from the prep to the opposing, you'll need to prep more conservatively and then adjust after closing the typodont. If you make a provisional stent from the pre-op tooth and use just clearance as your goal, your temp will be thin in some areas. Hopefully, the graders understand that this is a flawed approach. Always base your prep design on the desired final restoration.

Dear Dr. Stevenson, Is there any way to judge the buccal and lingual taper of #5 PFM? Also, instead of chamfer bur like the one in the video, is it alright to use a 856016 for the lingual chamfer? I have noticed that controlling the bur 887709 is a little challenging and makes the margin pointy and scratchy for me. Could you also please share about the transition zone for shoulder and chamfer interproximally for #5 ? Thank you. Best regards, Adi

@StevensonDentalSolutions Жыл бұрын

Look at the prep from the facial view and each wall should be leaning inward at about 1 second on a clock - this would give 12 degrees of total occlusal convergence. The 856-016 would be fine, although the margin will not technically be a chamfer, it will be a fillet, which is designed for ceramics and not metal. The majority of dental schools don't understand this...so using it and calling it a chamfer won't cause any issues.

@Adi-jj5ih Жыл бұрын

Dear Dr. Stevenson, I have a couple of questions. 1) Sometimes when trying to get Interproximal clearance going from the occlusal to gingival I get like a heap of material and it wastes a lot of time to cut down and then make a margin there. Any suggestions on how I can avoid this step? 2) If the typodont can be brought to occlusion, what is a good reference point during exams to check if there's adequate occlusal clearance? Constraints - There's neither putty nor RGS to measure. Thank you. Best, Adi

@StevensonDentalSolutions Жыл бұрын

Reduce the facial and lingual axial walls first, then the IP clearance will be a smaller job, and faster. 2. Use the shank of a friction grip bur and insert between at a 30 degree angle (parallel to the reduction planes on the facial) - all shanks for friction grip measure 1.6 mm. Also, you can use the 330 bur vertically at the marginal ridge areas of the prep - the bur can provide you with valuable reduction information (1.5 mm long bur)

Dear Dr. Stevenson, Thank you so much this incredibly informative video. I have a question.. Some universities don't provide appropriate burs for interproximal reduction. Mostly it's 016 or 018. In that case, is it possible to do a crown prep without over reducing the MD axially? Also, do you have any recommendation for using the fine burs towards the end in dry cutting? I struggle with getting mesiocclusal and distocclusal surface being somewhat sharp. Thank you in advance. 🙏

@StevensonDentalSolutions Жыл бұрын

It's unfortunate that some Universities don't re-exam their bur sequences. You are 100% correct, the 106 and 108 burs will not fit between the IP areas without causing over-reduction. You'll need to find a thinner bur - even a carbide, like a 169L or 699...Dry cutting is a secret of master clinicians and has been known to be the best mode for refinement for many decades. Unfortunately, a poorly executed study over 50 years ago scared the dental world into the over-use of water to "protect" the pulp. The over-use of water coolant leads to over-prepping! A light touch, new burs and air coolant have been very safely used with no pulpal consequences by thousands of experts. Use the side of the tip to round off the mesial and distoocclusal line angles, or even use an abrasive point (something that you might use for polishing composite).

When you have a proximal resto subgingival, how do you approach the interproximal area to crown prep on sound tooth. I place a thick retraction cord, yet it bleeds and get a notch on the margin. It becomes extremely time consuming. Is there a better and a faster way especially in upper premolars.

if i were to prep number 29 for a metal crown are these the same steps you would take? how much reduction do you want on the buccal or lingual side? is it 1.5mm on the buccal and 1.0mm on the lingual like you would do for a molar such as 30? how does this prep differ from doing it on a premolar? THANK YOIU

@StevensonDentalSolutions 4 жыл бұрын

Premolars and molars are the same with respect to dimensions for cast gold: 0.5 mm chamfer 360 degrees and 1.5 occlusal clearance. The axial wall reduction will simply result naturally as you follow the taper desired and the secondary planes. For PFM, it's usually best to reduce about 1.0 mm on the lingual finish line - this allows a minimal collar. The facial finish line is 1-1-5 - ideal is 1.2 or so.

Look at the prep from the facial and hold the tapered diamond along the long access of the prep - use the adjacent contact areas as a guide, then move the bur to the mesial and see that it should not touch any area above the internal of the axial-finish line - if it does, th=is is your under cut area - use the bur as positioned to remove it, then repeat øn the distal. For buccal lingual undercuts, look at the tooth from the occlusal with one eye closed - make sure that you can visualize the entire chamfer/shoulder without any of the axial wall restricting the view. IF you find a tight spot, remove the upper portion of the axial wall in this area first and re-evaluate. If it's still undercut, take the bur all the way to the finish line and lean the bur towards the center of the tooth (perpendicular to the undercut) - this should help...

Use a coarse finishing disc on the walls to eradicate undercuts. More conservative than using a bur.

Excuse me my inglish is verry bad. How do you push the finish line to inder gingival ? Do you excercise a strenght for préparation teeth ? Pouvez vous me montrer une photo d' une latérale préparée (j'ai l'habitude d'avoir une latérale très petite).

insérez d'abord la corde de rétraction dans le sulcus, puis préparez doucement la ligne d'arrivée. Utilisez une fraise de coupe pour affiner la marge.

Please define all planes?

@StevensonDentalSolutions 2 жыл бұрын

C plane = the non-functional cusp reduction. B plane = the central facing reduction and A plane = the functional cusp bevel.

I live 7 minutes from your San Dimas location. Do you see patients there at all? I need a good dentist for an upper denture or partial. I doubt I can afford implants. Blue shield 65÷ Dental plan.

Excellent technique for dental students who start learning principles of crown prep. In a real world teeth that need crowns are usually Broken down , are not wholesome and you cannot measure your reduction. Many teeth are smaller than ideal in size and form and in respect To gingiva. If a practicing dentist does not know how to do a prep by now, he should quit dentistry and sell watermelon for a living . Also the question is what type of crown this prep is for. I mean what material. Crown prep is the function of material the crown is made of.

PFM. Unfortunately the vast majority of dentists prep teeth very substandardly, and take even worse scans and impressions. Where do they learn to be better after dental school? CE courses, sitting in a lecture room? Not possible! You need many years of mentoring by a master clinician to become an excellent clinician. I recommend to dentists, many of whom have many years of experience or are faculty or prosthodontists (in my study club for example) to engage themselves in learning more, opening their minds and eyes. and joining me in Chicago each year at the American Academy of Restorative Dentistry for example - such a great group to be a member of - they are the best of the best, and no-one even knows their names for the most part. I ask my mentees to try to be humble, for they don't know what they don't know. All dentists can become better if they have a passion for it. Preparations in the mouth can be glorious and even more ideal than this demo. Thank you for being so honest about your attitudes towards our profession - it is quite revealing. Sincerely, Rich Stevenson

I can't see why a student could not close the typodont bite in order to check prep clearance. This sounds like the typical university bullshit and another unnecessary stress for the student. BTW with the materials we have these days PFM's seem redundant. I have not done one in over 10 years. These types of preps are really just testing dexterity and bur control.
