Sinus augmentation for dental implants: The use of alloplastic materials

The ability to augment the sinus floor has dramatically expanded the scope of implant dentistry. Clinical and scientific studies abound as to the efficacy of this procedure. The debate still ensues as to the best material to use for this augmentation, with autogenous bone, freeze-dried bone, xenografts, and alloplasts all being advocated. This article will substantiate through scientific and clinical studies, how the use of allplastic materials in sinus augmentation techniques can greatly reduce the morbidity and the expense of the procedure while predictably producing bone that has been shown to support dental implants in function for extended periods of time.
