Dental implants may achieve predictable and high success rates when placed in sites with adequate bone. When bone deficiencies are present, various techniques and materials have been used to augment the maxilla and the mandible for implant placement. A number of systematic reviews have been performed to examine implant survival in augmented sites. It appears that implants placed when horizontal augmentation has been performed achieve survival rates similar to those of implants placed in native bone. The augmentation of vertical bone defects is more challenging, and implant survival rates reflect this difficulty. The use of mictotextured implant surfaces and staged implant placement appears to provide improved results. This presentation will review implant survival rates in onlay augmentations and discuss methods to improve outcomes.
