Dental Implants Implant Anatomy & Components 3

Question 1

The macro-design feature of implant threads primarily serves to:

Accepted Answer

Increase initial stability and distribute occlusal load

Answer

Thread design affects primary stability and load distribution; aggressive threads provide better purchase in softer bone types.

Question 2

What distinguishes a one-piece implant from a two-piece implant system?

Accepted Answer

The abutment is integrated into the fixture with no separate component

Answer

One-piece implants combine the fixture and abutment in a single unit, eliminating the micro-gap at the connection but limiting prosthetic versatility.

Question 3

Which implant diameter is typically classified as a 'narrow diameter implant' (NDI)?

Accepted Answer

Less than 3.5 mm

Answer

Narrow diameter implants are generally defined as those with a diameter less than 3.5 mm and are used in sites with limited bone width.

Question 4

The implant collar (also called the neck) refers to:

Accepted Answer

The coronal smooth portion just below the platform

Answer

The implant collar is the smooth or micro-threaded coronal section that interfaces with crestal bone and soft tissue.

Question 5

What is the purpose of micro-threads in the coronal portion of some implant designs?

Accepted Answer

Preserve crestal bone by transferring functional stress

Answer

Micro-threads at the implant neck help transfer functional stresses to the crestal bone, stimulating bone maintenance and reducing marginal bone loss.
