DPC materials can be classified into:
Discuss
Answer & Solution
Answer: Option A
Solution:
DPC materials can be classified into 3 categories. The categories are flexible materials, semi rigid materials and rigid materials.
22
DPC materials should ideally be flexible, where differential thermal movements occur.
Discuss
Answer & Solution
Answer: Option A
Solution:
Flexible materials are the best. DPC materials should ideally be flexible. Under differential thermal movements flexible material do not crack or puncture.
