If you just came from my reel, welcome. And if you have a bench exam coming up please read every word of this before you buy a single bur, watch a single YouTube video, or tell yourself you will figure it out when the time comes.
Because that is exactly what I said. And it cost me six months.
The Moment I Realised I Was Not Ready š
When I got my UNMC interview I genuinely thought I was prepared. I am a dentist. I trained for years. I know what a Class II preparation should look like. I know the depth of the axial wall. I know you need to break the proximal contact without touching the adjacent tooth. I know what a proper PFM finish line feels like. I know what occlusal reduction should measure.
I knew all of it in my head.
But when I sat down at that bench with the clock running and the pressure on I could not replicate it.
And that is the thing nobody warns you about. Knowing and doing are two completely different things under exam conditions.
What the Bench Exam Actually Looks Like š¬
Every school is different but here is the reality across most CAAPID bench exams:
You walk in. The school provides the equipment, the handpieces, the setup. You are not bringing your compressor from home. You are not using the same burs you practiced with for three months. You are working with what they give you and what they give you works very differently than your home setup.
At home your compressor pressure is lower. Your handpiece runs slower. You get used to a pace. You build muscle memory around that pace.
At UNMC I had to do a Class II preparation and a PFM crown. They evaluate your preparation on everything, your margins, your reduction, your wall depth, your finish line, your occlusal clearance, your proximal contacts. Every single detail is assessed.
And the handpiece at the school? It cuts fast. Faster than you are used to. Faster than you practiced. And if you are not ready for that you will remove too much. Or too little. Or your finish line will be inconsistent. And you will not even realise it until it is too late.
Time is everything. If you are used to spending 45 minutes on a prep at home because your setup is slower you will panic when the same prep takes 15 minutes at school and you have no idea if you did it right.
The Setup Mistake That Costs People Thousands šø
I have seen people spend $2,000 building a home setup before they even understand what schools actually provide.
Fancy handpieces. Expensive burs. Full phantom head setups that cost more than a flight to the exam location.
And then they walk in on exam day and realise the school provides everything. Half of what they bought was completely unnecessary.
Here is what I tell every student now:
Start simple. Buy second hand. Build smart.
You do not need the most expensive setup. You need a functional setup that mimics exam conditions closely enough to build real muscle memory. A decent phantom head, a basic compressor, and the right burs ā that is it.
Speaking of burs ā this is where I see students overthink it the most.
You do not need fancy burs. For a Class II you are working with a 245, an 330 bur, and that is essentially it. For crowns you need a shoulder bur, a thin tapered diamond, and a football bur for occlusal reduction.
That is your whole bur kit. That is what you will actually have access to in most bench exams. Everything else is noise.
I spent money on burs I never used. I bought things I saw in videos that looked impressive and turned out to be completely irrelevant to actual exam conditions. I am telling you this so you do not do the same.
Why Watching YouTube Was Not Enough For Me š±
I watched Stevenson. I watched Duggan. I watched every single video I could find.
And I want to be clear those resources are not bad. They are genuinely helpful for understanding the concept of what a preparation should look like.
But here is the problem.
In those videos you see beautifully set up phantom heads, perfect lighting, premium burs, and techniques that are polished and refined. And what you walk into at a bench exam is nothing like that. The burs you see in those videos you will not have access to 80% of them on exam day. The setup looks different. The pressure is different. The time is different.
Watching a perfect prep being done by someone in a controlled environment does not prepare you for doing your own prep under pressure for the first time.
I know this because I watched every video available and still walked into UNMC unprepared.
What I needed was not more videos. What I needed was someone to look at MY prep and tell me specifically what I was doing wrong and exactly how to fix it.
Not just "this margin is off." But WHY it was off. What I did in my hand movement that caused it. And what I needed to change to make sure I never did it again.
That did not exist anywhere. So I built it.
Why I Did Not Do Stevenson or Duggan's Course š¤
I want to be honest about this because I know a lot of students go straight to these courses and spend $5000 to $10,000 for five to ten days of in-person training.
I did not do it. And here is why.
I already knew the theory. I already knew what the prep should look like. Five days of being taught what a Class II should look like was not going to fix the fact that I could not replicate it consistently on my own.
The only thing that was going to fix that was sitting at home and prepping 100 plus teeth myself. Repetition. Building real muscle memory. And having someone evaluate what I was doing wrong along the way.
That is what actually works. Not one week of theory you already know. Repetition plus targeted feedback.
I spent months prepping teeth at home. Slowly. Obsessively. Fixing the same mistakes over and over again until they stopped being mistakes. And by the time I was ready I knew every single thing that could go wrong in a Class II or a PFM prep and exactly how to prevent it.
What I Look For When I Evaluate a Prep š
When a student sends me their prep I am not looking to criticise. I am looking to diagnose.
There is a difference.
Most evaluation services out there will tell you "your margin is inconsistent" or "your axial wall depth is insufficient." Great. You already knew something was wrong. That is why you sent it.
What you actually need to know is: what did you do that caused this, and what do you change to make sure it never happens again?
That is what I do.
For a Class II preparation I am looking at:
ā Isthmus width ā is it one third of the intercuspal distance, no more ā Axial wall depth ā minimum 1.5mm into dentin ā Proximal box ā have you broken the contact without touching the adjacent tooth ā Cavosurface margins ā are they clearly defined, no feathered edges ā Pulpal floor ā is it flat and at the right depth ā Overall outline form ā does it follow the anatomy or has it gone outside
For a PFM crown preparation I am looking at:
ā Occlusal reduction ā minimum 1.5 to 2mm, uniform across the surface ā Finish line ā is it a clear, consistent shoulder or chamfer all the way around ā Axial wall taper ā 6 degrees total convergence, no undercuts ā Facial reduction ā enough space for the porcelain ā Surface texture ā smooth walls, no ledges, no steps ā Margin placement ā is it supragingival, at the margin, or subgingival as required
When I look at your prep I am not just checking boxes. I am watching your pattern. Where does the error start. What is the root cause. And what is the one thing you need to fix that will correct three problems at once.
That is what nobody else is telling you.
What Most Students Get Wrong and Why They Never Figure It Out šØ
Here is the honest truth.
Most students who fail bench exams or get waitlisted do not fail because they do not know dentistry. They fail because they practiced alone, identified that something was wrong, but never figured out why and kept repeating the same mistake 100 times thinking repetition alone would fix it.
Repetition without feedback just reinforces bad habits.
I know this because I did it. I prepped tooth after tooth at home thinking I was getting better. And in some ways I was. But there were specific errors in my technique that I could not see myself because I had no external eye on my work.
If I had had someone evaluating my preps every two weeks during those months of practice ā someone who could tell me exactly what I was doing and why I would have walked into UNMC ready. I would not have been waitlisted until December. I would not have spent six months in uncertainty wondering if this cycle was over for me.
That six months cost me more than money. It cost me time, mental health, sleep, and so much anxiety that I would not wish on anyone.
That is why I built the bench prep evaluation program.
How I Went From Waitlisted to the Fastest in My Batch at NYU šŖ
I want to be honest with you about something before I tell you about the evaluation program.
I am not going to sit here and call myself an expert. I am a D3 student. I am not a professor. I am not a course director.
But I am someone who prepped 200 plus teeth with her own hands. Someone who sat at a phantom head for months, alone, frustrated, not knowing what was wrong, and slowly painfully slowly figured it out.
After UNMC I did not give up. I went home and I prepped. And prepped. And prepped. My compressor was barely working. My setup was basic. There were days I had very few shots left and I had to make every one count. I watched my own preps over and over trying to figure out what was wrong. And for a long time I could not figure it out.
It was not until I got to NYU that everything clicked.
At NYU I sat with professors. I studied their evaluation guides. And I realised something that changed everything for me the school has a specific guide. A specific criteria. And if your preparation is even 0.5mm off from that criteria, it does not pass. There is no grey area. There is no partial credit for a nice looking prep that does not meet the exact standard.
Once I understood exactly what they were looking for and why everything changed.
The prep that used to take me 60 minutes? I now do it in 15.
One PFM crown. 15 minutes. With confidence.
I am now the fastest in my entire batch at NYU. I pass every single practical exam we have Class II, build ups, PFM crowns, all ceramic crowns on the first attempt with the highest marks. Every time.
And I want to be very clear about something. That did not happen because I am naturally talented. It happened because I prepped 200 plus teeth, failed over and over again, figured out exactly what the mistakes were, figured out exactly why they happened, and built the muscle memory to avoid them permanently.
Today I can look at any preparation and within seconds tell you exactly what is wrong, why it happened, and what you need to change to fix it. Not because I read it in a textbook. Because I have done it hundreds of times and made every single mistake myself first.
If I had not gone through those traumatising bench experiences ā the waitlist, the uncertainty, the months of practicing alone I would not be the clinician I am today. The people around me who never had to prepare for bench the way I did? I can see the difference every single day in clinic.
That is why I built this program. Not to teach you what a prep should look like. You already know that. But to be the person I never had someone who looks at YOUR prep, tells you exactly what YOU are doing wrong, and shows you exactly how to fix it before you walk into that exam room.
The Dental Sprint Bench Prep Evaluation Program šÆ
This is a six month program built around one thing: getting your hands ready before you walk into that exam room.
Here is exactly what you get:
ā Prep evaluations every 15 days you send me your preps, I evaluate them with specific targeted feedback not just what is wrong but why it is wrong and exactly how to fix it
ā A 1:1 session with me ā we go through your setup, your technique, your problem areas, and build a specific practice plan around where you are right now
ā A 1:1 session when you receive your bench invite so that in the final weeks before your exam you are fully prepared for exactly what that school is looking for
ā School specific guidance because every school is different. What UNMC evaluates is not identical to what Temple or UAB or Midwestern looks for. You will know exactly what your school wants before you walk in.
This is not a course that teaches you what a Class II should look like. You already know that. You went to dental school.
This is a program that takes where you are right now and gets you to where you need to be with someone watching your work every step of the way.

One Last Thing š¤
I got waitlisted until December.
December. While everyone around me was getting acceptance calls and planning their move to their new city, I was sitting at home not knowing if my cycle was over. Not knowing if I had to wait another full year. Not knowing if all of that work the INBDE, the CAAPID application, the KIRA, the candidate day was going to count for anything.
That feeling is something I would not wish on anyone.
And the worst part? It was completely preventable. If I had started earlier. If I had gotten proper feedback on my preps. If I had known what I know now.
You do not have to go through what I went through.
If you have a bench exam coming up or even if you think you might have one in the next six months ā start now. Not when the invite comes. Now.
