If an implant is not installed in time to replace the missing tooth, bone resorption occurs, or, in other words, the jawbone begins to settle in place of the missing tooth. Also, adjacent teeth begin to shift towards the missing tooth, and the tooth on the opposite jaw begins to shift outward and lengthen, which can cause traumatic and premature malocclusion, including disorders in the jaw joints.

Sinus lift is a bone regeneration, the purpose of which is to increase the volume of bone tissue by raising the paranasal cavity. This manipulation is performed only on the upper jaw.

OPEN SINUS LIFTING Is performed with insufficient amount of bone tissue on the sides of the upper jaw. First, the implantologist creates a small hole in the outer wall of the adjacent cavity. After that, the mucous membrane of the adjacent cavity is raised to the required height. The created free cavity is filled with augmentation material. A sinus lift also uses a membrane to obtain the maximum amount of bone possible. The previously layered bone tissue and part of the mucosa are laid back and sutured. After some time, the required amount of bone tissue is formed, after which implantation is performed. An open sinus lift is less traumatic for a patient than a closed one.

CLOSED SINUS LIFTING It is used in cases where the patient's bone is nearly sufficient for implant placement, but additional bone needs to be added. To insert the implant, a chisel is inserted into the drilled hole, which pushes the bottom of the cavity and raises the paranasal cavity. Then the osteoplastic material is poured into the cavity. The implant can be installed immediately, without even waiting for the

1. Titanium "screw" - an implant screwed into the jawbone. In accordance with the structure of the patient's jawbone, an implant of a certain length, width, with a certain number of threads and depth is selected. On the outside, the titanium implant is specially treated to increase the surface of contact with the bone and thus provide a better fusion of the dental implant with the bone (osseointegration). As a result of this process, an analogue of the tooth root is obtained so that the subsequent setting of the dental crown can be carried out.

2. Healing abutment. A specially shaped titanium abutment that is temporarily inserted into a dental implant above the gum level to create an aesthetically shaped gum around the dental implant, just like natural teeth.

3. Abutment. An analogue of the tooth shaft. After the Healing Abutment is removed, the abutment is placed and fixed in the dental implant. Depending on the choice of the patient, a metal or zirconium abutment is installed. The advantage of a metal abutment is the relatively lower price. It is suitable for patients with thick gums or in cases where the tooth is implanted deep in the mouth. On the other hand, a zirconia abutment is a more expensive but more esthetic solution if an incisor is implanted because the zirconia abutment does not show through thin gums. It is also used in cases where the patient plans to use a zirconia dental crown.

4. Dental crown. Depending on the choice of the patient, a metal-ceramic or zirconium crown is made, which is installed and fixed on the abutment. In appearance and functionality, a dental crown is identical to a natural tooth.
