Sinus augmentation with intra- vs extraorally harvested bone grafts for the provision of dental implants: Clinical long-term results
Quintessence International , 05/04/2012Deppe H et al.
Sinus augmentation procedures using intra– and extraorally harvested bone grafts can provide implant stability in the long term. However, major preoperative discomfort and more bone loss was seen when bone was harvested from the iliac crest. If autogenous bone is mandatory in sinus elevation procedures, extraorally harvested bone grafts can still be recommended, especially when bilateral procedures are indicated.
