While there may be a number of reasons for wanting a greater volume of bone in the posterior maxilla, the most common reason in contemporary dental treatment planning is to prepare the site for the future placement of dental implants.<unk>  augmentation<unk>  is performed when the floor of the<unk>  is too close to an area where dental implants are to be placed. This procedure is performed to ensure a secure place for the implants while protecting the<unk> . Lowering of the<unk>  can be caused by: Long-term tooth loss without the required treatment, periodontal disease, trauma. Patients who have the following may be good candidates for<unk>  augmentation. * Lost more than one tooth in the posterior maxilla. * Lost a significant amount of bone in the posterior maxilla. * Missing teeth due to genetics or birth defect. *<unk>  most of the maxillary teeth and need a strong<unk>  floor for multiple implants. It is not known if using<unk>  techniques is more successful than using short implants for reducing the number of artificial teeth or dental implant failures up to a year after teeth/implant placement.
