A new "platinum" standard for bone grafting: autogenous stem cells.

Autogenous bone has long been considered the gold standard of all bone grafting materials. However, complications have been associated with autogenous bone-harvesting procedures. This article suggests that an alternative approach, grafting with autogenous bone marrow aspirate, may become a new platinum standard. Bone marrow can be extracted from the large flat bones of the body with relative ease and safety, and it provides a rich source of adult stem cells as well as growth factors that facilitate osteogenesis. Mixed with a resorbable matrix or scaffold, bone marrow aspirate has the potential to reconstitute various bony defects in the mouth to reconstruct the severely atrophic maxilla and mandible. The potentiality and plasticity of stem cells have been well documented.

Antral membrane balloon elevation.

Many edentulous posterior maxilla are found to be encumbered by alveolar resorption and increased pneumatization of the sinus. These factors limit the quantity and quality of bone necessary for successful implant placement in these areas. One solution is to use shorter implants, but this often results in an unfavorable crown-root ratio. To create an improved environment in such regions, the classic sinus floor elevation with bone augmentation is a well-accepted technique. However, when the edentulous area is limited to a zone between 1 and 2 teeth, lifting the membrane becomes difficult and may subject it to iatrogenic injury. The antral membrane balloon elevation technique, which is introduced in this preliminary report, is a modification of the currently used sinus lift. It elevates the membrane easily and makes the antral floor accessible for augmentation with grafting materials.

Trephine bone core sinus elevation graft.

The sinus cavity often limits the amount of available bone for the placement of implants in the posterior maxilla. The sinus lift operation and graft is a technique that can add grafted bone in excess of 10 to 16 mm through a lateral wall quadrilateral osteotomy. However, when moderate alveolar atrophy is present, an osteotome technique can provide an average bone height in crease of 3.5 mm. This article presents the trephine bone core sinus elevation graft, which is intended to increase bone height 4 to 8 mm. This procedure is especially indicated when adjacent teeth are present and there is only moderate atrophy of the alveolus.
