Alternative to the gold standard for sinus augmentation: osteotome sinus elevation.

The development of sinus augmentation procedures has diminished the problem of proper implant placement in the posterior maxilla in patients that have a pneumatized maxillary sinus and reduced alveolar bone. The gold standard approach to augmentation--the external sinus augmentation--was developed years ago and is still touted as the best approach for creating maxillary posterior bone. However, external sinus augmentation procedures are often quite traumatic, time-consuming, and costly, and they have anatomical limitations and considerable documented morbidity.

Quantitative evaluation of extraction socket healing following the use of autologous platelet-rich fibrin matrix in humans.

Platelet-rich fibrin matrix (PRFM) is an autologous biologic material created by centrifugation of blood. This study quantified ridge changes associated with the healing of 21 extraction sites using PRFM alone as a graft. Standardized measurements of ridge width and height were recorded at extraction, after graft placement, and after 4 months of healing.

Alternative to the gold standard for alveolar ridge augmentation: tenting screw technology.

Studies have discussed the potential issues associated with the placement of implants in unfavorable locations. Today, it is possible to optimize implant placement despite the significant ridge resorption that often occurs after tooth extraction. This objective is achievable because techniques exist to augment resorbed alveolar ridges to prerequisite widths and heights for proper implant position.

Changes in alveolar bone height and width following post-extraction ridge augmentation using a fixed bioabsorbable membrane and demineralized freeze-dried bone osteoinductive graft.

Background: It has been shown that the amount of healed bone following guided bone regeneration (GBR) with demineralized freeze-dried bone allograft (DFDBA) and a bioabsorbable membrane is significantly less than the initial quantity. A study was designed to determine if the amount of GBR would be affected by using an osteoinductive DFDBA and bioabsorbable membrane and membrane stabilization.

Methods: Eleven extraction sites (10 patients) were treated with DFDBA and bioabsorbable membrane before placing endosseous implants.
