Spacing 2/5

Let's use a distance of 1.5mm as a rule of thumb.

We're going to keep our implants at least 1.5mm away from neighboring teeth.

It's useful to imagine a micro-crack radius around implants (illustrated by the green line)

Now how about adjacent implants? Remember, each implant creates micro cracks that radiate circumferentially.

What is the minimum inter-implant distance we should aim for?

In other words, we want our implants ____mm apart. (Fill in the blank)
