PassADC is an online study platform for the Australian Dental Council (ADC) Part 1 written exam. It includes 1,390 verified MCQs across all 10 subjects, 87 lessons, 33 OSCE clinical case walkthroughs, 3 full-length timed readiness trials and a 24/7 AI tutor - built for overseas-trained dentists.

How much does PassADC cost?

There's a free tier with all 87 lessons, 50 practice MCQs per day and one full 140-question readiness trial. Pro costs $49 AUD/month or $199 AUD per 6 months (about $33/month). Subscriptions cancel anytime and come with a 7-day money-back guarantee.

Does PassADC include full-length ADC-style mock exams?

Yes. PassADC includes 3 Practice-Readiness Trials that mirror the real ADC Part 1 format: 140 questions, a 4-hour timer and official blueprint subject weighting, with a full answer review after submission. Trial 1 is free.

What happens if I don't pass the ADC Part 1?

Members who complete the program and don't pass receive free Pro access until their next attempt - no forms, no questions.

How is PassADC different from cohort coaching courses?

There are no enrolment dates or cohorts to wait for - you start immediately, pay a fraction of the typical ~US$1,050 cohort price, and get a 24/7 AI tutor that explains any question in plain English instead of scheduled Zoom calls.

ADC Part 1 Prosthodontics: High-Yield Topics, Example Questions & Study Tips

Prosthodontics carries roughly 12% of the ADC Part 1 written exam - ≈34 of 280 questions. Below: the high-yield topics to master, the classic traps that cost candidates marks, an ADC-style example question, and how to study this subject efficiently.

High-yield topics for Prosthodontics

Topic	What to focus on
RPD design & Kennedy classification	class determination with modifications, support/retention/stability logic
Complete denture problems	looseness, pain, gagging - cause vs correction tables are exam gold
Jaw relations & occlusion	vertical dimension errors and their clinical signs, balanced occlusion principles
Crown & bridge fundamentals	preparation principles, ferrule effect, taper, finish lines and material choice
Post-and-core	when a post is needed (it retains the core, not strengthens the tooth)
Impression materials & techniques	material selection, border moulding, common defects
Implant-supported prostheses basics	screw vs cement retention trade-offs

Common areas candidates struggle with

Kennedy classification with modifications - the rule that classification is decided by the most posterior edentulous saddle, and mods exclude it
Diagnosing vertical dimension errors from clinical signs (cheek biting, angular cheilitis, closed appearance) instead of measuring
Choosing the right connector for RPD distal extensions - support and stress-breaking considerations
Ferrule effect and its clinical implications for crown-lengthening decisions
Post-and-core myths - a post retains the core, it does not strengthen the tooth

Classic exam traps

"A post strengthens the root" - it doesn't; it retains the core and can increase fracture risk
Mixing up increased vs decreased vertical dimension symptoms (cheek biting vs angular cheilitis patterns)
Kennedy classification after extractions - always classify from the most posterior saddle, mods exclude it
Choosing rigid connectors where stress-breaking is required in distal extension cases

Example ADC-style question

Question

A 68-year-old with a maxillary complete denture complains of angular cheilitis and cheek biting bilaterally. Which occlusal vertical dimension change is most likely?

Increased vertical dimension
Decreased vertical dimension
Correct vertical dimension
Increased freeway space

Answer: B

Decreased OVD causes over-closure - the corners of the mouth fold, trapping saliva (angular cheilitis) and the buccal mucosa is drawn between the occluding surfaces (cheek biting). Increased OVD would cause difficulty closing lips, tooth clicking and muscle fatigue.

This is one worked example. There are hundreds more scenario-based prosthodontics MCQs inside the PassADC question bank - with per-option explanations on the ones that matter most.

Key concepts to revise

Kennedy classification rules (including modifications)
Signs of increased vs decreased OVD
RPD design principles (support, retention, stability, bracing)
Ferrule effect - 1.5-2 mm of sound tooth structure required
Impression material selection by clinical scenario
Common denture complaints - cause-symptom-fix tables
Fixed prosthodontics preparation principles (taper, finish lines)

How to study Prosthodontics for the ADC Part 1

Make cause→symptom→fix tables for denture complaints; most pros questions are written exactly that way
Sketch RPD designs for each Kennedy class - visual memory beats rote lists

How to test your readiness in Prosthodontics

The exam tests this subject through clinical vignettes, so practise it the same way - scenario-based MCQs with explanations, not isolated fact recall. The fastest way to know whether prosthodontics is a strength or a gap is to take a diagnostic across all 10 subjects and compare your accuracy in this subject against the exam weighting.

Once you know where you stand, target the weak areas above with daily practice, review every wrong answer's explanation the same day, and sit at least two full-length timed mocks before booking the real exam.

Frequently asked questions

How is prosthodontics weighted in ADC Part 1?

Approximately 12% - about 34 of 280 questions. It has broad sub-topic coverage (removable, fixed, occlusion, implants) which makes it a big swing subject.

Does a post strengthen a root canal treated tooth?

No. A post retains the core, which retains the crown. Posts do not strengthen the tooth and can increase root fracture risk. The strength comes from ferrule (1.5-2 mm of sound tooth around the crown margin) and remaining coronal dentine.

What are the signs of decreased vertical dimension?

Angular cheilitis (folded lip commissures trapping saliva), cheek biting, over-closed facial appearance, reduced lower face height, and complaints of dentures 'not fitting' despite good extension.

What is the Kennedy classification for RPDs?

A classification of partially edentulous arches based on the location of edentulous areas. Class I = bilateral distal extension; Class II = unilateral distal extension; Class III = bounded unilateral; Class IV = anterior only. Always classify from the most posterior saddle; modifications describe additional edentulous areas.

Where do you actually stand?

30 questions weighted to the official ADC blueprint. Free, instant, no credit card.
