Internal sinus lift

In some patients, when planning implant surgery in the upper jaw, there is a problem of proximity of the implant's lining to the sinuses. In some patients, this is a developmental anatomical condition, while in some it is due to pneumonia of the sinuses after tooth extraction or long-term inactivity of the area. If we have a minimum of 6 millimeters of bone height, we approach the internal sinus lift, i.e. lifting the sinus chamber bottom through the implant's lining. After losing the mucous membrane at the bottom of the sinus cavity, the space is filled with an artificial bone preparation and an implant is placed, which requires 6 months to be osseointed and to create a new bone.


In the preparation of the procedure, the patient prepares an orthopantomographic footage and a cbc image, which together with the intraoral examination provides the basis for the therapy plan. During the examination at the clinic, the patient is familiarized with the procedure, filling out general health forms and signing the consent to the surgery. After determining the procedure for performing the procedure, the patient is also given the previous term for thoroughly cleaning the soft and hard deposits, at intervals of no more than 7 days. Also, the patient is introduced antiseptic therapy in the form of fluid for the lining of the oral cavity. Prior to the procedure the patient receives a standard premedication consisting of antibiotics, anxiolytics and analgesics.


Recovery after surgery occurs regularly without major problems, but with moderate to severe swelling. The patient may feel milder pain or tenderness because of stitches (if placed), which is alleviated by pain medications. The patient is advised to cool down the area of the procedure to reduce the pain and possible swelling. In all the operative interventions performed at our center, growth hormones isolated from the patient's blood are used, with the aim of faster healing and reduction of postoperative disorders.


By carrying out this procedure, the initial unacceptable region is transformed into a quality implant lining to ensure its long-term stability.


The most common complication of this procedure is perforation of Schneider's membrane (mucous membranes sinuses are coated with). Since its thickness is sometimes only 0.2 millimeters, and its elasticity decreases with age and in smokers, it is necessary to be very careful when manipulating. If perforation occurs, the procedure is delayed for 2 months, or the lateral window side elevation technique is used. In addition to this complication, infection, swelling and mild pain may also occur.
