them: no incisions, immediate temporization, excellent success rates.
The only complaints I have received are when the general dentist likes
ceramic crowns instead of porcelain/metal(PFM). The metal of the
implant affects the translucent appearance of the final crown so you
either use PFM or a 2 piece system.

My partner and I have been placing them since FDA approval about three
years ago. Some studies suggest higher crestal bone loss but so far we
havent seen that. These one piece systems make the job for the general
dentist ridiculously easy. Pretend it is a built up tooth and prep it
the way you want.

I am not a fan of Zimmer implants simply because we were running into
big problems with back orders and customer support. Their bone graft
materials on the other hand are good.

Dave:

No incision? Is there some kind of coring drill? I suppose by "one
piece" that means an integral fixture/abutment. I also think you might
not want to use these in cases that need grafting, or the grafting is
already done?

Yep, no incision but percutaneous. The initial pilot drill goes
through mucosa and to depth in bone, taking into account the thickness
of the mucosa. The bottom half looks like any other implant but the
abutment continues up from the threads in one piece. You can place
these with open flaps in certain cases like other implants but I
seldom do. If your questioning the width then graft first. After the
initial pilot hole is made, you insert an attachment that will allow
you to excise (like a cookie cutter) and appropriate diameter of skin
to finish implant placement.

I can imagine a problem if the fixture is put in too far off-line for
the axial inclination of the crown and the "abutment" portion has to be
reduced too much.

I dont think these are any harder from that standpoint. Ofcourse
angulation is important but you can prep these to your liking. I tell
the dentist to pretend this is a built-up RTC treated tooth. Just prep
the sucker. Take your impression if you like then make the temp. That
simple.
