Thanks a lot.
I am very concerned about screwing around with my sinuses, and will be
making this very clear to the oral surgeon.

I read there is a type of implant specifically designed for people
that need sinus lifts, which , according to the article I read,


"...can be placed in as little as 5.0mm of bone. They are called
Endopore and Innova Corporation fabricates them. There surface is
composed of thousands of tiny titanium spheres. This is the same
technology used by many orthopedic surgeons for hip replacement. These
tiny spheres tremendously increase the surface area, they also allow
the bone to function under tension.



This is not a very good implant. The surface is not good it should have
the texture similar to a golf ball also you want to have a thread and a
microthread to stabilize the implant. After placing any implant there
is a risk of bone resorbtion this can be up to 3mm if you only have 5mm
of bone there will be nothing left to hold the implant. You need to
leave the technical aspects of the procedure up to the oral surgeon,
there is a lot of marketing claims out there for all sorts of implants
and gadgets and you need to go to somebody who is familiar with what
works and what the majority of the industry uses as a standard.

In 2.0-3.0mm of bone a properly trained skilled surgeon can create the
opening for the implant push the floor of the sinus up through this
opening, place the bone graft and then the implant. This procedure is
referred to as a sinus lift through crestal approach. It is much more
conservative than the sinus lift procedure you referred to."

This is the first type of sinus lift I described. Again 3mm does not
give you much room for healing, it has nothing to do with being a
skilled surgeon. Anybody who attempts a sinus lift unless they are a
complete idiot, has accumulated the necessary skill otherwise they
would not even attempt the procedure because of risk of failure.


Then the article goes on to say:


"Finally, a spark erosion precision partial denture is another option.
There is nothing on the roof of your mouth. It is virtually
undetectable. After you place it in your mouth a"jewelry like" clasp
is closed and it is extremely rigid."


Do you know about these alternatives?


Yes. there are many types of dentures including spark erosion that when
combined with implants can leave nothing on the roof of your mouth.
Spark erosion is a more ridgit type of prosthesis which depending on
how it is designed, may be too ridgit and work against you.



If what you are picking for yourself does not sound invasive now, wait
until it fails. Assuming your surgeon and dentist agree to your
proposal. Your surgeon may also not do osteopore implants. There are
other short implant systems other than Osteopore, such as Bicon this
does not mean that it is the best option for you. You need to consider
the size of the tooth the implant will be replacing and the load it
needs to carry. If you sinus expands further naturally after implant
surgery and you have a short implant and have not added bone for
aditional barrier your implant will get loose and fail.

Thank you so much for your answers.My student surgeon said what you
just said.

He said he will be giving me the - I'm not sure I wrote this down
right, but - a lateral, crestal approach type of sinus lift, and that
it was more conservative.

I hope I'm not his first one! I assume the prof will be there to do it
or supervise... (Am I playing with too much fire here? by letting a
student do a sinus lift?)

I was only somewhat comfortable with him doing the implant surgery -
he says he has done about 20 - but now a sinus lift? Should I run
screaming from this procedure being done by a student?

Problem is, it's either this or get it done in another country. I
cannot afford regular oral surgeon implant prices, here...

The school is charging me only $4700 for the 5 implants and sinus
lift.
Then the graduate student offic will charge me $850 each for the
crowns.
