How to Prepare for the Dental Bench Test

Bench Test Guide · Advanced Standing Applicants

Bench test preparation is motor-skill training, not revision. You cannot cram it in the last week the way you can cram a written paper, because hands do not learn that way. This page has two halves: first, exactly how we train students in the Bench Test Course with Dr. Kaur, and then the preparation plan to run around it, including the build order, the criteria that quietly cost marks, and the tips that make the difference on the day.

Mastering Bench Test Preparation with Dr. Kaur

Before the plan, here is the course itself: seven live days on Zoom, one preparation at a time, preparations only, and then a practice week with unlimited evaluations. It is built around the one thing you cannot do alone, which is having your own work judged against the criteria US programmes grade on.

$1,100Course fee
7 daysLive sessions on Zoom, one preparation at a time
1 weekPractice and evaluation week afterwards, unlimited submissions
2Certificates: participation, and competency on clearing the exam

What enrolment includes

Demo

A live demonstration before every preparationDr. Kaur takes the full sequence on Zoom, start to finish, before you cut anything. You then perform the same preparation yourself.

Feedback

Individual feedback on your own workThis is the core of it. Your preparation is critiqued against the criteria US programmes grade on, you are told exactly what to change, and you cut it again.

Pacing

A fixed sequence, a flexible calendarThe order of the preparations does not change, but the dates can. Take extra practice days between sessions whenever you need them.

Practice

A full practice and evaluation weekAfter the live sessions you get a dedicated week to practise, with no limit on the number of preparations you may submit for evaluation during it.

Exam

A competency exam at the endSet to bench-test standards rather than to a classroom standard, so passing it means something on the day.

Certificates

Participation and competency certificatesEvery student receives a Participation Certificate. Clearing the competency exam adds a Competency Certificate.

Photos

Bench-test photo evaluationsPhotograph your preparations and submit them for review by US-licensed faculty. Evaluations are included with enrolment, and more can be requested afterwards for an additional charge.

Materials

Study materials and checklists providedYou arrange your own armamentarium: handpieces, burs, a typodont, mounted teeth and a mounting pole. Everything you study from, we give you.

Who teaches itDr. Kaur, faculty at The Study Boards and a US bench-test specialist, with mentoring alongside Dr. Stevenson, Dr. Trehan and Dr. Duggan. Every programme grades a little differently, so the teaching is built on structured sequence plus deliberate practice rather than on one school paper.

The sequence, session by session

Each session is a live demonstration, then your own guided attempt, then practice guidance before the next one.

Day 1Mandibular molar, Class II amalgamOutline form, depth control, proximal box design, and the grading checklist you will be marked against from here on.
Day 2Maxillary molar, Class II amalgamOcclusal anatomy considerations, box extension strategy, and the errors that most often get a preparation rejected.
Day 3Premolar, Class II amalgamDovetail principles, contact preservation, proximal refinement, and holding the outline on a smaller tooth.
Day 4Full gold crownOcclusal reduction sequence, functional cusp bevels, taper control, axial wall height and finish line continuity.
Day 5PFM crownMetal-ceramic design, shoulder to chamfer transitions, porcelain support, thickness planning and margin execution.
Day 6All-ceramic crownMaterial-specific reduction, rounded internal line angles, and margin design that resists fracture.
Day 7Bridge, plus Class II and III compositeAbutment alignment, path of insertion and parallelism strategy, then how composite preparations differ from amalgam.

If the group needs it, a revision and doubt-clearing session is run at the end of the seven days.

What the course does not coverPreparations only. We do not teach wax-ups, wax carving or temporary crown fabrication, and we will not pretend otherwise: if a school on your list sets one of those, that practice sits with you. The one reported exercise outside the set, the USC onlay, has its own add-on on the USC ASPID bench exam page.

The full curriculum, written out session by session, is in the bench test course blueprint, and the current cohort arrangements are on the course page. The rest of this guide is the preparation plan to run around it, and it is useful whether or not you train with us.

Step one, before you cut anything

Find out exactly what your schools set

This decides everything else you do. Exercises differ between programmes, and practising the wrong preparation well is still the wrong preparation.

Our school-by-school breakdown lists what candidates have reported at 24 programmes. Some are operative heavy, some are crown heavy, and some include a wax carving or a removable partial denture design, which are different skills from a crown preparation and need their own practice time. Treat that list as a starting point, then confirm with each programme once your invitation arrives.

Six things to ask the programme in writingWhich teeth and which preparations. How long you get in total. What you bring and what they provide. Whether a temporary crown or a wax exercise is included. Which typodont and mounting they expect. Whether the preparations are graded separately or as one exercise.

Write the answers down. Candidates lose weeks practising what a forum post said a school asked three cycles ago.

Where are you starting from?

Your runway depends on how recently your hands did fixed preparations. Pick the line closest to the truth.

Choose the line that describes you.
Shortest runway

Your problem is the criteria, not your hands

Daily clinical work keeps your hand steady, but clinical habits and bench test criteria are not the same thing. In the clinic you finish a margin where the tooth and the patient allow. On a typodont you are marked against a standard, and on most schools criteria that margin is expected to sit about 0.5 to 1 mm above the gingival contour.

Start with the criteria, a timer and the exercises your schools actually set. Cut each one, have it assessed, and fix one named fault at a time. Weeks of short sessions will usually do it, but do not skip the assessment step, because the faults that cost you marks are the ones you have stopped noticing.

Rebuild control first

Expect the first preparations to feel slower than you remember

Hand control comes back quickly, but not instantly, and the first few preparations usually show it in wall smoothness and taper. Work in short sessions two or three times a week rather than one long weekend session. The gap between sessions is part of how the skill consolidates.

Spend the first stretch on operative preparations only. Move up to crowns when your walls, boxes and margins come out the same way twice in a row, not the first time one attempt looks good.

Longest runway, start now

Build from the simplest preparation upwards

Give yourself the most time and the plainest sequence. One Class II amalgam, assessed, repeated until it is consistent. Then the rest of the operative set. Then single crowns. Bridge work only if a school on your list actually sets it.

The mistake here is jumping to the hardest exercise because it feels like serious practice. It teaches you to manage complexity you do not yet have the control for, and those habits are hard to undo later.

Triage

Practise only what that school sets, and practise it under time

With an invitation in hand, general practice stops. Write down the exact exercises, then rehearse them end to end under exam conditions, more than once. Time the whole thing, including setting up, not just the cutting.

Get at least two of those rehearsals assessed by someone who grades to US criteria. And sort your travel so you arrive the day before. Candidates who fly in on the morning are the ones who feel rushed, and rushed hands show on the typodont.

Stop adding volume

Repetition without correction makes a fault permanent

More repetitions will not fix this, because you cannot see your own work the way a grader does. Practising a fault carefully is still practising a fault, and it is the quiet ones, a fading finish line or a wall a couple of degrees out, that decide results.

Photograph your next preparation from the same three angles, mark it yourself against the criteria, then have it assessed and compare the two lists. The gap between your reading and the grader reading is your actual study plan.

The order that works

Build in sequence, simple to complex

Each stage teaches control that the next one needs. This is the same direction of travel the course follows, and it is the opposite of practising whatever you feel like that evening.

Stage 1A baseline you can be honest aboutCut one preparation, timed, with no help. Photograph it and have it assessed. You cannot plan a runway without knowing where you are starting, and a baseline that embarrasses you is more useful than an estimate that flatters you.
Stage 2Operative preparationsClass II amalgam on a mandibular molar, a maxillary molar and a premolar, then Class II and Class III composite. This is where outline form, depth control, proximal box design and smooth walls get built, and all of it carries into crown work.
Stage 3Single crowns, in this orderFull gold crown, then PFM, then all-ceramic. Occlusal reduction, functional cusp bevels, taper, axial wall height and finish line continuity are easier to learn in that order, because each preparation adds roughly one new demand to the last.
Stage 4Bridge work, only if a school sets itAbutment alignment and path of insertion are a different problem from a single crown. This is where candidates chase a perfect parallel look and end up with walls too parallel to pass.
Stage 5Full rehearsals under exam conditionsSet out exactly what you will have on the day, start the clock and do the whole exercise without pausing. Do it more than once. The first rehearsal tells you about your timing. The second tells you whether you actually fixed it.
The test for moving onTwo consecutive attempts that meet the criteria, not one attempt that looked good. Consistency is what the exam samples, because you only get one try on the day.
Make the hours count

What one good practice session looks like

Short and frequent beats long and occasional. A session with one aim and a record at the end teaches more than three unstructured hours.

1Name the one thing you are fixing this session, and write it at the top of the page.
2Set the timer before you pick up the handpiece. Every session, including the early ones.
3Cut the preparation straight through, without stopping to tidy as you go.
4Stop when the time is up, in whatever state the preparation is in. That information is the point.
5Photograph it from the same three angles every time, so you can actually compare week to week.
6Mark it yourself against the criteria before anyone else sees it.
7Have it assessed by someone who grades to US criteria.
8Write down the single fault you will carry into the next session.

Two or three of these a week will take you further than one long Sunday. The rest days are not wasted time; the gap between sessions is doing part of the work.

Where the marks actually go

The faults that cost marks, and why they happen

These are the ones our faculty see again and again on submitted preparations. Each one has a cause you can practise against.

Margin

Polishing the margin smooth at the endMargins have to be smooth and well finished, but the common habit is to keep polishing at the very end until it looks right. Repeated polishing over-reduces, drives the margin closer to the gingiva and leaves it rougher, not smoother. With most schools wanting it about 0.5 to 1 mm above the gingival contour, one habit loses marks twice: once for the margin, once for the gingival damage.

Depth

Occlusal reduction, over or underOne of the most common reasons candidates fail, usually because the reduction guidelines were not known or not followed. And graders do not only read the index you cut: they can judge your depth by comparing with the adjacent tooth. Learn the numbers for the preparation, then verify them two ways before you move on.

Taper

Over-tapered, or too parallelBoth come from the same root cause: not knowing the correct handpiece angulation, or working without a reference point. In bridge preparations candidates often go too parallel while chasing a perfect looking result, and that fails as surely as over-taper does.

Adjacent

Nicking the adjacent tooth, then hiding itIt happens, and on its own it is survivable. What turns it into a bigger loss is quietly polishing it away, which usually damages it further. Tell the examiner. Identifying your own mistake is acceptable. Concealing it is not.

Finish

A finish line that disappearsFinish lines have to stay continuous and readable all the way round, including at the line angles, which is exactly where they fade out. If you cannot see it under good light, do not expect a grader to credit it.

Time

Losing the middle, rushing the finishMost candidates lose time in the middle of an exercise and then rush the last few minutes, which is where the visible marks are. That is a timing fault, not a hand skill fault, and it only ever shows up in timed rehearsals.

If you want the full marking picture before you plan your practice, read how the bench test is graded and why candidates fail.

Tips and tricks

Twelve things that quietly make the difference

Small habits, most of them free. Build them into practice now so they are automatic when it counts.

Lay your tray out the same way every single time.On the day you want your hand to find the instrument without your eyes leaving the tooth. This is free marks, and it costs nothing to practise.
Rehearse the first five minutes until they are automatic.Setting up, orienting the typodont and making the first cut is where nerves do the most damage. Make that part muscle memory and the rest settles.
Fix your reference point before you start, not halfway through.Taper goes wrong when the handpiece angle drifts because there was never a reference to hold it against. Decide what you are referencing, then keep your eye on it.
Check reduction twice, and in two different ways.Your own index, then a straight comparison against the adjacent tooth. A grader can do the second one, so you should too.
Get the margin smooth as you cut, not by polishing at the end.The end-of-exercise polish is the habit that over-reduces and pushes the margin into the gingiva. Smooth early, then leave it alone.
Look at the clock at the halfway point, not at the end.Every candidate who runs out of time found out too late. Halfway is when you can still change the pace.
Plan the proximal box path before the bur touches the tooth.Most adjacent tooth damage happens in the first seconds of the box, when the bur is moving before the path is decided.
If you do nick the adjacent tooth, say so.Tell the examiner rather than quietly polishing it. Concealing it usually means more damage, and it is the concealment that costs you.
Photograph every preparation from the same three angles.Memory flatters your work. Photographs do not, and they let you compare this week against last week honestly.
Practise in the position and clothing you will work in.Loupes, gloves, stool height, elbow position. Change any of those on the day and your hand is doing something slightly new.
Carry spare burs, and know which bur did which job.A worn bur changes your feel and your timing. Running out or switching blind in the middle of an exercise is an avoidable loss.
Travel the day before, and sleep.Candidates who fly in on the morning are the ones who feel rushed, and tired hands are slower and less steady. It shows on the typodont.

What to do with the time you actually have

Pick your runway. The shorter it is, the narrower your practice should get.

1Confirm the exercises at every school on your list, in writing.
2Baseline one preparation, assessed, in the first week.
3Operative set until two consecutive attempts match the criteria.
4Single crowns in order: full gold, then PFM, then all-ceramic.
5Bring in the clock well before you feel ready for it.
6Finish with two full rehearsals under exam conditions.
The point of this phaseUse the early weeks on the exercises you are worst at, not the ones you enjoy. The enjoyable ones are usually the ones you are already good at.
1Practise only the preparations your school has set. Nothing else.
2Time every session from the first one, setup included.
3Get at least two full rehearsals assessed, not just single preparations.
4Fix one named fault per session instead of everything at once.
5Book travel so you arrive the day before, not on the morning.
The point of this phaseNarrow is the whole strategy here. Two preparations rehearsed properly beat six practised loosely.
1No new technique this week. Five days is not enough to learn one.
2Two complete rehearsals, both timed, both end to end.
3Check your kit against the school list and pack spare burs.
4Rehearse the first five minutes until setting up is automatic.
5Sleep. Tired hands are slower and less steady, and it shows on the typodont.
The point of this phaseIf something is still not working in the last week, change the plan rather than the technique: slow the middle of the exercise down and protect the finish, because that is where the visible marks are.
Your setup

Practise on the setup you will be graded on

Students arrange their own armamentarium: handpieces, burs, a typodont, mounted teeth and a mounting pole.

Practise with the bur set you will actually bring. A different bur changes your reference points, your feel and your timing, and the morning of the exam is a poor time to find that out. If a programme names a specific typodont or mounting, practise on that one.

Mount it the way the exam mounts it, too. A preparation that is comfortable at your own angle on your own desk can be a noticeably harder exercise in a fixed position, and access is half of control.

Preparations only, and what that means for youThe Bench Test Course with Dr. Kaur covers preparations. We do not teach wax-ups, wax carving or temporary crown fabrication. If a school on your list sets one of those, give it separate practice time and ask the programme exactly what it expects. Temporary crown work is the skill most candidates have practised least, and it shows immediately in fit, shaping and timing.
The part you cannot do alone

Everything above is practisable alone, except the assessment

That is the step that decides whether repetition helps you or quietly hardens a fault, and it is what the course with Dr. Kaur is built around. The full breakdown is at the top of this page.

Quick answers

Frequently asked questions

How long does bench test preparation take?
It depends entirely on what your hands have been doing. A dentist cutting restorations most days can be ready in weeks of focused, assessed sessions. Someone several years out of clinical work should plan in months. The number that matters is not weeks on a calendar but consistency: two preparations in a row that meet the criteria, rather than one attempt that came out well.
Can I prepare properly without anyone assessing my work?
You can practise, but you will not see what a grader sees, and repetition makes a fault permanent rather than fixing it. At a minimum, get the specific preparations your school sets assessed by someone who grades to US criteria before you spend weeks repeating them.
Which preparation should I start with?
A Class II amalgam on a molar. Outline form, depth control, proximal box design and smooth walls all transfer into the crown preparations that come later, and the exercise is simple enough that faults are easy to see.
How much does timing really matter?
Enough that you should practise against the clock long before you feel ready. Most candidates lose time in the middle of an exercise and then rush the finish, which is exactly where the visible marks are. Untimed practice hides that completely.
What if my school sets a wax carving or an RPD design?
Some programmes do report those, and they are separate skills from preparations, with their own material and their own practice time. Plan for them separately and ask the programme precisely what it expects. Our course covers preparations only.
Do I need a particular typodont?
Some programmes name one, so ask. Practise on what they name, and mount it the way the exam mounts it. Access and angle change the exercise more than candidates expect.
Is the course built around one school?
No. It teaches the preparations schools most commonly grade, and candidates come in with different school lists. The one reported exercise outside that set is the USC onlay, which has its own add-on.
