What is dental bone grafting?

Sometimes a dental implant  cannot be used  because there is not enough bone to support it. In reality, this lack of bone can be compensated for by an advanced surgical technique: dental bone grafting (or bone regeneration). This technique consists of bone augmentation through the patient’s own bone transplant or using biocompatible external bone .

In the first case we speak of an “autologous” dental bone graft ; here the bone is taken from the mandible and from the patient’s jaw, but it may also be necessary to take it out of the oral cavity, for example from the pelvis. In this case it is necessary to admit the patient who must undergo general anesthesia and must therefore be hospitalized.

In the second case we are talking about a “heterologous” dental bone graft , that is bone not taken from the patient. The most used is the deproteinized bovine bone. The advantage of the latter is that it avoids intervention for bone removal from the patient.

How to perform dental bone grafting

There are several techniques to perform dental bone grafting, but the most widespread is that which consists in applying a special membrane , below which to insert the material that will form the new bone. The resorbable or non-resorbable membrane is inserted to protect the filling material positioned below it, thus facilitating the maintenance of the clot in situ, the starting point for the formation of new bone .

In the case of dental bone grafting with autologous bone, that is the patient’s own, the operation is very complex and requires two separate surgical procedures, while that performed with external bone (bovine bone) is simpler but can lead to poor blood circulation of the bone. In the case of external bone, we use one of the safest and most reliable materials bovine bone deprived of the organic component, extremely biocompatible. Once sprayed with blood, it allows the formation of new natural bone in the patient.

Bone graft and dental implant 

Inserting a dental implant to replace a missing tooth requires a certain amount of bone. In several cases the bone may be missing and the causes may be natural or incorrect extractions. One of these is the extraction itself, which in fact, can cause a pronounced bone resorption especially if a lot of time is allowed to pass.

In the event that the height of the alveolar ridge of the upper arch is reduced, the maxillary sinus is raised , an operation performed under local anesthesia. This operation causes an increase in bone volume in the upper arch which allows the insertion of implants of adequate length and diameter. With the restoration of bone volumes the floor of the maxillary sinus is moved upwards.
