Match the following

• Osteosynthesis

• 1. the pathological destruction or disappearance of bone tissue.

• osteolysis

• It is a surgical procedure to treat bone fractures in which bone fragments are joined with screws, plates, nails or wires

• radiolucency

• is the black or darker area within a bone on a conventional radiograph

• biofilm

• 1. a thin, slimy film of bacteria that adheres to a surface.

What is the main advantage of PEEK over metal implants mentioned in the text? (multiple correct answers)

• Lower biocompatibility

• Closer elastic modulus to human bone

• Higher price

• Radiolucency in imaging

Which bacterial strain showed greater adhesion to titanium specimens than PEEK?

• E. coli

• E. faecalis

• S. aureus

• S. mutans

How was the bacterial adhesion on implants evaluated in the study?

• By studying the topography of the implants with SEM

• By measuring the weight of the implants

• By analyzing the chemical composition of the implants

• By using a computer simulation
