Which statement is true about Type 14 impressions compared to Type 4 in terms of speed and impression quality?

• A. Type 4 is faster and higher quality
• B. Type 14 is faster and generally higher quality
• C. Type 14 is slower and lower quality
• D. Type 4 is faster but lower quality

Answer: (B)

Impression materials are judged by how quickly they set and how accurately they reproduce detail. Type 14 is designed to cure faster than Type 4 while also maintaining, and often improving, detail reproduction and dimensional stability. That combination means you can complete impressions more quickly and with fewer distortions or remakes, leading to generally higher quality results. So, Type 14 being faster and generally higher quality is the best description.
