2. When we mention sinus lift procedure, this sinus surgery
does not refer to the treatment of sinusitis and its associated
symptoms.In truth, sinus lift is more linked to dentistry.
Sinus lift, also referred to as sinus augmentation, is
conducted in patients with bone mass deficiency in the
maxilla or with too close a distance between the maxillary
sinus and the jaw.
This is a well known procedure among patients who have lost
their teeth and opt for dental implants over the application of
dentures.
So, when is sinus lift surgery needed?
• For patients who don't have the upper molars or ample
bone mass in the upper jaw for implants.
Anatomy-wise, the back of the upper jaw has fewer bone
than the lower jaw.Tooth loss results in bone being
assimilated back into the body (a process known as
resorption).
• Patients whose teeth have been missing for an extended
time. (prolonged resorption has led to significantly
diminished bone)
• Patients who have lost bones due to periodontal disease
• Implants cannot be added in when a patient has
enlarged maxillary sinuses that are too close to the upper
jaw. It is vital to point out that sinuses become bigger with
age.
Sinus lift procedures are normally done by a dental specialist.
This surgery would fundamentally entail bone mass
enhancement in the rear of the maxilla or upper jaw,

3. particularly between the jaw and the maxillary sinuses
The bone that is utilized in the sinus lift may either be taken
from the patient's own body (autogenous bone), usually from
the iliac crest of the hip or the tibia, or from a cadavre
(allogeneic bone).
Bone from an animal contributor may also be employed.
Before the surgery, a patient must have his or her jaw and
maxillary sinus scanned first, with an x-ray or CT scan, for
the dentist to properly determine the size of the bone
structure and evaluate the sinus health.
The sinus lift can also be seen as gum graft surgery.
Initially, a cut is made in the gum tissue where the teeth
were once found.
The gum tissue is cautiously elevated to show the bone.
The surgeon will then create a small, oval window through
the bone.
Between the maxillary sinus and the jaw, a thin
membraneous wall will be shoved up and away from the
maxilla.
Bone-graft material is then crammed into the space where
the sinus was.
Using sutures, the surgeon will close up the cut, once the
bone has been fully filled in.
A wait time of about 4 to 9 months is needed for the grafted
material to stick with the bone, before implants are added in.

4. One can conveniently discover animation or video clips of this
procedure from various dentistry or dental surgery web sites.
Considered a day surgery, this type of surgery requires
around 7 to 10 days of recuperation time, though some mild
soreness may be felt after the procedure.
Some other problems that may develop are inflammation in
the operative site and bleeding from the mouth or nose.
There is also the probability of undoing of sutures and
shifting of bone graft material when blowing the nose or
sneezing vigorously.
By keeping the nasal lining wet with the use of saline sprays,
sneezing can be prevented.
For patients with allergies, it is recommended to have the
surgery conducted before or after known allergy seasons.
So as to induce fast recovery and prevent infection, the
dentist may suggest antibiotics and an antimicrobial
mouthwash.
There are a few complications that must be anticipated with
this procedure.
Some of these complications are the non-integration of bone
with the bone-graft material or the graft site does not grow
its own blood supply.
With the shortage of live bone for the dental implant to affix
to, the possibility of implant rejection is greater.

5. Sinusitis is another problem that may occur with sinus lift.
Sinusitis may occur if the sinus membrane is pierced or torn
during surgery.
For patients with chronic sinusitis due to a nasal polyp,
dentists are hesitant about undertaking the procedure.
Fortunately, sinus lift procedure can be conducted combined
with polyp removal surgery.
