Compensation of dental bones

Compensation of dental bone allows the installation of dental implants for patients whose jaw bone does not have sufficient height and / or thickness to support the implants.

This type of bone compensation or the addition of artificial bone differs from the compensation around the teeth during periodontal flap surgery as a treatment of periodontal surgical procedures. For this kind of purposes remuneration will be limited, which involves adding a little artificial bone around the tooth, because of its strengthening and lifetime duration.

Compensation of the bone for implant surgery is among serious and complex procedures. Patient’s bone mass is needed for this kind of procedure which was largely inferred by removing a small amount of bone from the hip, ribs or head, but today this procedure is abandoned and the bone from the jaw itself is used mixed with artificial bone mass and then returned to the patient’s jaw in a very large amount. New research shows that the best result, ie the best quality of new bone is achieved by combining 50% of the bone of the patient and 50% of artificial bone. Such a mixture is always covered by a membrane in order to create a barrier between the compesated soft tissue and the bone, and thus ensure a smooth regeneration of the bone tissue.

Not all bone compesations in dental implantology are the same, so depending on the needs of the patient some of the following four types of fees can be done:

– It often happens that after installation of the implant there is part a of the implant that comes out from the bone, so the necessary compensation bone around the implant must be implanted. This type of compensation is generally the easiest and mostly involves the use of a combination of artificial bone and membrane around the implant.

– Enlarged sinuses are very common after the loss of teeth in the lateral regions of the upper jaw, which makes it impossible to incorporate implant without raising the mucous membranes of the sinuses and providing support to future bone implants, because otherwise they would floated in the sinus cavity. The sinus cavity is fed a mixture of artificial bones and bone of the patient, after which it can be accessed to installing of implants.

– Bifurcated reefs can be very thin and therefore suitable for installation of dental implants. The thinnest dental implant has a diameter of 3.5mm, and for it to be incorporated into the bone, the bone thickness is required of at least 5-6mm. If the bone is narrower than 5mm it is necessary to perform compensation of bones and increase its thickness. There are many techniques for this type of compensation – from removing the bones from another place and transfer to the region to the exclusive use of artificial materials, as well as the combination of artificial materials and the bones of the patient.
Based on the views and 3D panoramic orthopans the best treatment is brought for each patient.

– In the lateral regions of the lower jaw is a common phenomenon that an important nerve is located shallow in the bone, so his position prevents installation of implants. In such cases, greater bone height is achieved by compensating, although it is possible, though far less frequently for the dentist to decides to move the nerve.

Procedure of compesation of bones can be quite invasive than the installation of implants and generally prolong the procedure of installing the implants itself, especially when incorporation of implants and compesation of bones can not be done during the same session, so it is necessary to compensate the bone first then wait a few months. Also, every surgery carries potential complications, although they are not common.

One way of overcoming the problem of the lack of bones, especially in recent times, is the use of shorter and narrower implants, which can be an alternative for reimbursement of bones. Of course, this option has its drawbacks, so that a specific treatment plan depends on the situation of the patient.
