Bone regeneration of the jaw bone with autologous three dimensional bone grafts (autotransplantation with bone blocks)
The atrophic jaws and the their bone defects do not allow the correct placement of dental implants. So the patients have no other choice but that of complete dentures.
This new method restores the anatomical morphology of the jaws, so that the patient is finally able to enjoy a perfect functional and aesthetic result.
The causes of bone atrophy vary. The most common are:
Advanced periodontical disease
Bone absorption after extractions
Removal of multiple incised teeth
Excision of endobone tumors
What are the bone blocks?
It is about compact three dimensional bone pieces, sometimes of different size than bone autograft which is obtained from the patient most commonly from the inferior of the mandible. Their purpose is to rebuild the defective area of the maxillary in order for it to be ready to receive the implants which are to be placed.
Why we prefer block from the patient himself?
It is not possible to create a bone without the existence of osteoblasts
It is not possible to create a bone from heterologous or alloplastic bone transplants without the deficit point to be surrounded by at least two bone walls.
The new bone should host the loaded dental implants
During the procedure the transplant is taken and it is placed in the defective area. In this new position it is immobilized with small screws of osteosynthesis, followed by a waiting period of 3 months. During that period the transplant is integrated into the existing one, and thus it increases the size of the jaw, where the implants will be placed. After the waiting period, the doctor is in a position to place the implants. It is a simple process that lasts half an hour and usually the patient is under local anesthesia.
