Sinus lift open
SINUS L LIFT (Open Sinus Lift)
Difficult conditions for the insertion of implants are most often found in the posterior alveolar regions of the jaws : as a result of pneumatisation of the sinuses (with age) and when teeth are missing, the alveolar process atrophies.
One of the methods that allows us to use implants in this particular area is the sinus floor liftand the insertion of autogenous bone or biomaterials into the space created between the floor of the maxillary sinus cavity and the elevated mucosa lining this cavity.
The high success rate of this type of procedure and the possibility of a single-stage implant insertion have led to the rapid adoption of the sinus lift procedure in implant treatment planning.
The healing of implants, inserted with a sinus floor lift, usually proceeds without complications, although the time is significantly prolonged.
The elevation of the maxillary sinus floor opens up new possibilities for implant treatment, as it allows implants to be inserted in difficult anatomical conditions, especially in lateral sections within the jaw.
LATERAL APPROACH METHOD
With the lateral approach method, we can lift the sinus 5.0-8.0 mm more than with the closed method, which is why they are performed most often.
- First, a window of access to the sinus floor is created and then the sinus membrane is gently undermined.
- The area prepared in this way is filled with biomaterial and covered with a special barrier membrane and mucous membrane, before being carefully closed again.
- The healing time is approximately six months.
- In exceptional cases where the existing bone thickness provides primary implant stabilisation, it is possible to insert implants at the same time, but this does not shorten the healing period.
