The macro-design feature of implant threads primarily serves to:
Answer: Increase initial stability and distribute occlusal load
Thread design affects primary stability and load distribution; aggressive threads provide better purchase in softer bone types.
What distinguishes a one-piece implant from a two-piece implant system?
Answer: The abutment is integrated into the fixture with no separate component
One-piece implants combine the fixture and abutment in a single unit, eliminating the micro-gap at the connection but limiting prosthetic versatility.
Which implant diameter is typically classified as a 'narrow diameter implant' (NDI)?
Answer: Less than 3.5 mm
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.
The implant collar (also called the neck) refers to:
Answer: The coronal smooth portion just below the platform
The implant collar is the smooth or micro-threaded coronal section that interfaces with crestal bone and soft tissue.
What is the purpose of micro-threads in the coronal portion of some implant designs?
Answer: Preserve crestal bone by transferring functional stress
Micro-threads at the implant neck help transfer functional stresses to the crestal bone, stimulating bone maintenance and reducing marginal bone loss.
A cemented crown on an implant compared to a screw-retained crown has which notable disadvantage?
Answer: Difficulty retrieving excess cement that can cause peri-implantitis
Excess cement extruded subgingivally during cementation can cause peri-implant inflammation and bone loss if not completely removed.
