Which design principle ensures that the prepared cavity resists displacement or fracture when the restoration is loaded during chewing?
Show answer and explanation
Correct answer: Retention and resistance forms
Retention form helps keep the restoration in place; resistance form ensures the tooth-restoration complex can withstand occlusal and functional forces without fracture. Both are core principles of cavity design.
