What are difference between sinus lift techniques?

Sinus-liftingModern dental implants in dentistry are available in a full range of different techniques. One of these techniques is a sinus lift procedure. It is a pre-implant surgery with the necessary indications. The aim of the sinus lift procedure is to graft extra bone into the posterior maxilla (upper jaw bone), as it is required for dental implants. This surgery is performed when the floor of the sinus is too close to the roots of posterior teeth where dental implants are to be placed.

Anodontia is characterized by bone resorption leading to the reduction in the size of bone, which is not enough for dental implants in the upper jaw. Restoration of the required amount of bone tissue directly affects the healing of the implant and the success of the entire dental implant procedure.

The preparation for sinus lift surgery is just as important as the preparation for placing dental implants. You need to have the initial dental consultation, to undergo diagnostic examination and visit allied medical specialists. And only then it is possible to take the decision about the techniques of the sinus lift procedure: there are two techniques of maxillary sinus floor augmentation: direct and indirect.

The indirect technique is used if the bone height is at least 7-8 mm and the direct one is used if the height is less. Both processes consist of three stages. With the indirect techniques firstly the bone is made thinner with the use of osteotomes, then soft tissues are exfoliated and bone graft material is placed into the newly created space.

The direct sinus lift involves a large amount of surgical procedures. In the direct sinus lift a small window is opened on the outside of the sinus wall and a small opening is created in the bone, which is also filled with bone material.

Each of the techniques has its indications and contraindications, and must performed strictly in accordance with them. Dental implants can be placed while performing the sinus lift surgery or after it. If the height of the bone is minimal, it requires from 4 to 6 months for healing and bone regeneration after the sinus lift procedure. If implants are placed simultaneously with the sinus lift procedure and the process of loading should be increased gradually. It will allow the bone to recover and regenerate after grafting. The patient should under the regular medical supervision in the postoperative period.

Complications are possible, regardless of the technique, but as a result of poor dental implant hygiene or non-observance of certain restrictions after the sinus lift procedure. The specialists of the company Bio3 Implants remind that it is important to refuse from air travel, sports, heavy lifting, climbing stairs, trips to the mountains for a month during the adaptation period after the sinus lift surgery. You also need to cough, sneeze, clear nasal cavities very carefully in order not to disrupt the restoration of bone tissue.
