Basic classification of impression materials

Hi! I’m Adam, a 3rd-year dentistry student, and I’ve prepared this short educational summary to help fellow students better understand the different impression materials used in dentistry. This guide covers the classification of materials based on rigidity, reversibility, and setting mechanisms—along with brief overviews of their properties, uses, and commercial examples. Whether you’re revising for exams or refreshing your knowledge, I hope this helps make impression materials clearer and more approachable!
