The threaded implant is the most common type of implant design today. There are different configurations of implant threads along with the requisite manufacturer's claims of supperiority... they all work essentially the same.

1. They stabilize the implant when it is initially placed.
2. They increase surface area.
3. They provide a great means of proprioception for the dentist placing the implant giving lots of information about the implant site.

Require pre-tapping for placement into very dense bone.

My choice as the most versatile and effective implant in the group.
