The sinus-lifting operation involves the build-up of bone tissue in the maxillary sinuses. They are located in the upper jaw on the left and right sides. Basically, in humans, the roots of the teeth are located in the maxillary sinuses. After their removal, there is an insufficient amount of bone tissue to install the implant. The sixth and seventh teeth are located near the maxillary sinuses.
The implant can be installed only if the bone has 10 mm to the maxillary sinus. If this is not enough, then the doctor should raise her bottom. The main indications for sinus lifting surgery:
- at a distance of 8-10 mm to the sinus, a closed operation is performed;
- with a bone tissue of 5-8 mm, an open operation is performed;
- at a distance of less than 5 mm, an open procedure is performed without the installation of implants.
It is worth noting that the sinus-lifting procedure is not suitable for everyone. Contraindications include: diabetes mellitus, recent surgeries, radiation therapy. Another limitation is the inflammation of the maxillary sinuses. To determine the focus of inflammation, you need to contact an ENT specialist.
