Lateral Window Sinus Elevation Technique

If there is an advanced bone defect in the upper jaw during implant prosthesis planning, access to the bottom of the sinus is opened by a lateral window method. Oceotomy (removal of bones) at the lateral sinus part of the Schneider's membrane (sinus mucous membranes) is applied to it. The resulting space is filled with a mixture of artificial bones and growth hormones separated from the patient's blood. Depending on the thickness of the bones on the ridge, the desired number of implants can be set at the same time to bring the newborn bones together.


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 plan, filling out general health forms and signing the consent to the surgery. After determining the plan 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. In addition to this complication, infection, swelling and mild pain may also occur.
