Why Sinus Lift Bone Grafting
is Not All That Big Of a Surgery
By Dr. Hamid Ryan Kazemi
Dentist
Some dentists discourage their patients from having sinus lift bone grafting to
get dental implants because they portray it as a ‘big surgery’ and instead offer a
conventional dental bridge which has its many problems. And some patients
simply avoid getting implants because of their anxiety or fear about bone
grafting. Lets face it- the name itself, ‘sinus lift’ does not exactly sound gentle!
Having performed sinus lift bone grafting now for almost twenty years, I thought
it would be helpful to review some facts about this procedure and what it really
is.
Sinus lift bone grafting is indicated in
patients who are missing their upper
back teeth and have inadequate
height of bone for implant placement.
This inadequacy is often due to the
position of the maxillary sinus which
lies right above the second premolars,
first molars, and the second molars.
With this technique, we can elevate
the sinus level and predictably
regenerate the necessary bone for a
successful and long term replacement
of teeth with dental implants.
To give some perspective, I often use the extraction of an impacted wisdom
tooth as comparison to sinus lift bone grafting. Almost everyone has their
wisdom teeth removed and there is hardly any hesitation about it. In fact,
dentists recommend it in almost every individual. So lets compare a sinus lift
graft procedure to extraction of an impacted wisdom tooth:

When we compare the two procedures, we see that patients have practically the
same experience. In fact, there is more swelling and pain associated with
extraction of a wisdom than a sinus lift procedure. In many ways, the sinus
lift procedure is gentler and less ‘traumatic’ than a tooth extraction.
Sinus lift bone grafting, while a sophisticated and highly skill-intensive
procedure, is nothing more than a pocket where some graft material is packed.
It is a delicate procedure and when done properly, it is a highly predictable and
successful procedure.
Many people have the wrong perception when it comes to the seriousness of
sinus lift bone grafting, which in reality is a gentle and minimally invasive
procedure. I think it is important to offer this procedure to patients who want to
replace their teeth more naturally with implants and avoid the many pitfalls of a
conventional bridge. Don't get intimated by the name nor the description by a
dentist who may not be well informed. It is a minor procedure and in my view, a
much safer and less traumatic surgery than getting a wisdom tooth out.
And that's a fact.
