Bone deficits can result from periodontitis, tooth loss, or following accidents. Bone reconstruction is therefore necessary, especially for treatment with implants. Bone reconstruction uses either bone grafts taken from jaw areas where there is “surplus” bone or proven bone replacement materials. The area from which the bone graft is collected will also regenerate to replace the removed bone. In some cases, bone replacement materials are a very successful option, but they are not suitable for all types of reconstruction.
The most common and successful reconstruction method takes place in the maxillary posterior region of the upper jaw; the procedure is known as a “sinus lift”, and bone replacement graft material is placed under the mucosal membrane of the maxillary sinus as a guide for the newly generated bone to grow.
We recommend low-dose 3D imaging of the maxillary sinus both before and after the sinus lift to enable mapping of the anatomy in the region and to plan the positioning of the implant. In France, not carrying out this imaging during the course of diagnostics is considered malpractice.
