Sinus lifting – is a procedure that may be required for implantation of the teeth in the upper jaw. In a situation where the volume of bone tissue for implantation is not enough, the bone needs to be increased. For this, the doctor raises the bottom of the laxative sinus and in the space that is formed introduces a special bone material. It takes several months to create a new bone of the desired thickness at this site, and the doctor was able to carry out implantation.
