Sinus augmentation complications: etiology and treatment.

Sinus augmentation, either osteotome or lateral window approach, is a predictable procedure to augment vertical height that allows for proper implant placement in areas with previous limited restorative options. Like any surgical procedures, there is always a risk of encountering either intrasurgical or postsurgical complications. A Medline literature search of articles published from 1984 to 2006 related to complications following sinus augmentation were selected and analyzed.

ABC sinus augmentation classification.

Edentulism in the posterior maxilla can present with compounding variables that make it a difficult region to restore with implants. Pneumatization of the sinus floor is typically accounted for during surgical treatment planning, but other factors such as horizontal ridge deficiency and vertical defects may be overlooked. This report reviews the different classifications used to treat the posterior maxilla and introduces a new system that incorporates all factors critical for implant success.

Cortical bone thickness in dentate and edentulous human cadavers.

Background: A critical component of treatment planning in dental implant therapy is the amount of available bone. Thick cortical plates have been the primary way to achieve primary implant stability. However, information about cortical bone thickness in various regions of the maxilla and mandible is largely missing.
