Raising the bottom of the maxillary sinus
Implantological treatment is the most similar to nature when it comes to supplementing dental deficiencies. Unfortunately, in order to be able to implant a tooth implant, the patient must have adequate width and height of sphery. One of the limitations of implantation surgery in the lateral section of the upper jaw is often the low-falling maxillary sinus. This is because every year after the removal of the lateral teeth, the vertical dimension of the bone in the lateral section occurs. This process is very slow, but it proceeds continuously. When the thickness of the bone in the vertical dimension decreases below 8~10 mm, the procedure for raising the bottom of the maxillary sinus becomes necessary. This procedure allows to increase the vertical dimension of the bone and implant implantation. Depending on the size of bone tissue loss, the procedure to raise the bottom of the maxillary sinus is divided into open and closed:
- Closed sinus lift – we use it when the thickness of the existing bone is more than 6~7 mm, the application of bone-forming biomaterial is carried out through a hole drilled to implant the implant. Special tools – osteotomes we lift the mucous membrane of the sinus in order to create a free space between the membrane and the bone of the appendicitis. Then we place a bone-forming biomaterial or platelet-rich fibrin A-PRF in this space and implant the implant at the same visit. The course of the closed sinus lift procedure is illustrated by animation.
- Open sinus lift – we use it when the thickness of the existing bone is less than 6~7 mm. The procedure begins drilling the window in the lateral wall of the bay. After lifting the mucous membrane, through the created window we apply bioplastic material or a rich platelet fibrillation A-PRF. The implantation procedure, depending on the indications, is carried out on the same visit or only after the period necessary to produce new bone tissue.
- Is lifting the bottom of the maxillary sinus painful? – In modern dentistry there is no place for pain. In our office we have several types of anesthesia – this allows us full and accurate anesthesia and thanks to this we carry out all treatments painlessly.
- Is it possible to return to work normally after the procedure? – after the sinus lift surgery, you should refrain from heavy physical activities for a few days, and you should not fly during this period. After the procedure, the dentist prescribes appropriate medicines to facilitate healing and provides written instructions on post-treatment procedures, any indications and post-treatment contraindications.
- Are implants implanted at the same visit as sinus lift? – the decision to implant implants immediately when raising the maxillary sinus or after some time is made by the doctor when planning the procedure and depends on several factors. Among other things, from bone thickness at the site of the planned implantation.
- After what time can treatment be completed after raising the floor of the maxillary sinus? – the time for implant healing is the same as with standard implantation in the upper jaw and is 6 months. After this period, the final crowns can be performed and treatment can be completed. In exceptional cases, this period may require an extension. It depends on the anatomical conditions of the patient and the scope of the sinus lift procedure.
