My doctor says I need sinus lift procedure. What are the major risks I could face with a sinus lift procedure? And do I really need a sinus lift for implants?
Firstly, in the hands of an experienced surgeon a the sinus lift procedure is pretty predictable nowadays.
That being said, the conventional lateral wall sinus lift has the following risks:
a. Sinus perforation
b. Infection requiring additional treatment
d. Tenderness & stiffness with muscles of mastication, difficulty opening mouth & speaking
e. Prolonged, or heavy bleeding, hematoma formation, & bruising at surgical site
f. Damage or sensitivity to adjacent teeth
Once again it is vital to seek out an experienced surgeon, who will perform the sinus lift, so you can mitigate any risks.
Notwithstanding the above, you will most probably need a lift if there's insufficient bone to stabilize the implant and allow it to heal.
In terms of alternatives to a sinus lift, your surgeon may suggest a short, wide diameter implant(ie. Bicon, Endopore...etc.) if he/she is comfortable with this technique within the anatomical limitations.
In addition, some situations allow a mini-internal lift to be performed, This is much less invasive, but still has risk. You should discuss this with your surgeon
