Bone formation for dental implants
In case the height of the bone under the sinus floor does not allow the implant to be inserted without penetrating the sinus cavity, a sinus lift should be considered, a treatment in which the height of the jaw is thickened by adding bone substitute (material that over time becomes bone) to this area.
Sinus lift
Due to the anatomical limitations in the back of the upper jaw, in many cases performing implants in this area will require a complementary treatment called sinus lift.
The goal of this treatment is to create a sufficient bone height for the support of the implant.
The maxillary sinus (or nasal cavity) is an air bubble within the face located between the upper end of the teeth and the lower border of the eye orbit (socket).
When the height of the bone below the floor of the sinus does not allow the implant to be inserted without penetrating the sinus cavity, a sinus lift should be considered. In this treatment the height of the jaw is thickened by adding a bone substitute (a substance that over time becomes bone) to the area where it is required.
The treatment is performed under local anesthesia or with the help of intravenous sedation , and in many cases the insertion of the implants can be combined with the surgery to lift the sinus, which will shorten the waiting time between the surgery and the construction of the teeth on them.
In some cases, a high concentration of platelets produced from the blood can be combined to improve the recovery process from the treatment.
If you have been told that a sinus lift is needed to perform transplants - there is no reason to worry. This is a treatment performed daily by oral and maxillofacial surgeons, and with the help of a strict surgical technique the likelihood of complications is not high.
Bone graft
Whether due to an infection that has absorbed the jaw, a missing tooth for a long time, or the natural anatomy, it is sometimes not possible to perform an implant without reshaping the jaw by bone grafting.
And
There are different categories of bone grafts that differ in the type of implant material:
And
Autogenous bone : A self-bone taken from another area of the body (pelvis, skull, lower or upper jaw). This type of bone graft has an advantage as it uses living cells that have been present in the patient's body for many years, so the chances of absorption and success are the best.
Bone Substitutes (or "Artificial Bone") : Bone substitutes come from different manufacturers and are based on a variety of materials. What is common to all is the creation of a kind of matrix in the required area into which a new bone is built. The big advantage of using bone substitutes is that it is a off-the-shelf product that does not require additional surgical site. The downside however is that this type of bone graft is not suitable for every case.
And
It is important to remember that every site that needs a bone graft is unique and requires different treatment.
In order to plan the appropriate surgery, appropriate X-rays are needed, a decision about the type of rehabilitation planned, and an assessment of additional factors that affect the treatment plan.
