Maybe I read your first suggestion wrong. Do you favor cementable or
screw-retained implant prostheses?

If you angle a screw-retained implant towards the labial in the anterior
region, you'll have a screw hole coming out the facial. This is an
indication for a cementable crown and abutment. An indication for a
screw-retained crown is where the gingiva cuff is so deep that you'd never
be able to get all of the cement out of the sulcus.

I never do this. I let the lab do it for me.

It takes less than 30 minutes to snap an implant impression...and another
20-30 to deliver it. The lab bill is a little bit more ($100-200 or so),
but you more than make up for it on the time savings.

I really like Branemark's new Replace Select, but if I'm concerned about
placement/alignment, I avoid the Easy Abutment and have the lab fabricate a
custom abutment.
ITI's system is nice in the posterior region, but the surgeon's don't like
it as much because they have to be extremely precise with the depth of
placement (crown margin is on the implant, not the abutment).
Calcitek/Sulzer/Centerpulse/Zimmer is the one I learned on. Good system,
but a couple of more steps than the other two. And I seem to see bone loss
to the first or second thread...but then it stops.
I've only restored 3i and Biohorizons one time each.

Ho!!! I wrote that bass-ackwards.... Sorry... must be the ADD...

100% correct. I got this bass-ackwards... You want to angle the implant
toward the palatine and the crown towards the labial so you can hide the
crew and covering on the palatine (lingual) side.

100% correct: the Local Implant Guy says that there is NEVER a situation
where you can control the cement. Remember you don't have a periodontal
ligamnet nor a sulcus to limit the penetration of the cement. There will
always be traces of cement around the collar and this causes
inflammation. The hydraulic forces placed on the cement as you push the
crown down onto the abuttment is enough to damage this fragile area.

Up here, as soon as you mention implants, the lab fee practically
doubles.

This is good to know. Most of the young upstart generalists who are
advertising that they will place implants for the dentists are pushing
this system. The Sudimplant (France) may put and end to this loss ( it
has a zircon collar that apparently forms a better 'attachment' to the
gingiva).

Living in Florida, I get to see dentistry from all over the world. What's
really interesting is that I get to see so many different techniques to
tackle the same problems. I saw an implant-retained spark erosion denture
the other day that was absolutely rock solid 10 years after placement. It
was made so well, that I called the dentist in Indiana who made it to get
the lab's name and number...and then had the dentist give me a crash course
on its fabrication.
I get to see what works, and what doesn't...without having to go through the
trial and error process myself. The down side? I have to keep basic parts
in stock for about 20 different precision attachment systems, and at least 5
different implant systems...and I still get patients coming in weekly with
something I haven't seen before.
