Preclinical preparation review

Describe a structured review of a typodont exercise.

Original teaching scenario / OSCE

Your practical station

You are asked to review a completed typodont exercise. Describe the observation sequence and give specific feedback rather than only a pass/fail judgement.

Recognise and interpret

Assessment compares the preparation with the specified exercise while preserving appropriate tooth structure.

1

Confirm exercise

State the tooth, surface and intended task.

2

Inspect

Assess outline, access, surfaces, margins and unintended damage.

3

Reflect

Relate each observed defect to function and the marking criteria.

At the viva table

Try answering aloud, then open the suggested answer. Examiner questions vary.

01 / Can one preparation shape suit every restorative material?

No. The design depends on the task and material.

02 / Why inspect adjacent surfaces?

Unintended damage is part of preparation assessment.

03 / Does a shiny surface prove correct geometry?

No. Evaluate all required features.

04 / Why use a rubric?

It makes feedback systematic and reproducible.
