• Yes

• No

What are the most widely used systems of dental implants in clinical practice?

• internal friction connection

  &

  non-conical connection

• hex-type connection

  &

  internal friction connection

• hex-type connection

  &

  non-conical connection

Match the following

• The connection is done via frictional force

• Internal Friction Connection

• A butt joint interface

• external hex-type connections

• The abutment is connected to the implant by an abutment screw

• Other name for Hex-Type connection

Instability in the connection between the implant and the abutment lead to the disruption of the soft tissue seal

• Incorrect

• correct

Select the causes of abutment mobility

• loosening of the abutment screw

• Elongation and loosening of the screw

• Instability in the connection between the implant and the abutment

• Fracture of the abutment or implant

Less screw loosening occurs in this type of implant:

• External

  connection-type implants

• internal connection-type implants
