Onlay bone grafting to the anterior maxilla: preparation for placement of implants.

Placement of implants in the dental alveolus of the maxilla is limited by bone width and the height of bone between the alveolar crest, the maxillary sinus, and the floor of the nose. In the anterior maxilla, the thin cortices can be split and grafted, or an onlay graft can be positioned on the labial/buccal cortex. This paper and presentation discuss the onlay bone graft to the anterior maxilla. This surgical procedure enables implant placement in previously deficient bone within the maxilla.
