Question

What are Ceramicand Polymeric implant materials? Explain.

Answer 1

Answer:

Ceramic implants:

Ceramic implants were introduced to overwhelm some esthetic and biological problems that can arise from titanium. The first ceramic dental implant was made from alumina (i.e., aluminum oxide, Al2O3) between 1960s and 1970s, and that was the only ceramic material used until recently.

polymeric implant material :

Many polymers have been used in soft tissue implant sites. Materials that are widely used include silicone rubbers, polyethylene and Teflon.

Answer 2

Answer:

Therefore, when you are sitting beside a campfire, almost a hundred percent of the heat that you receive from the fire is transferred through thermal radiation. This is why the side of your body facing the fire gets hot while the side facing away from the fire stays cold.
