Abstract: Sinus floor pneumatization following tooth extraction in the posterior maxilla commonly complicates the placement of dental implants. When feasible, short implants less than 8 mm in length have been shown to be successful in managing these cases. However, in the majority of cases, sinus lifting is required for placement of dental implants of a standard length or in combination with short implants. Common practice has been to utilize a lateral window approach when the residual bone height to the sinus floor was 5 mm or less. Crestal sinus lift is a minimally invasive procedure with lower complication rate compared to the lateral approach. Densah lift protocols utilizing the osseodensification method have revolutionized how we approach sinus floor elevation allowing easier treatment with far less complications. This presentation aims to present this modern technique, and highlight the guidelines and limitations of its use for optimal success.
Objectives: 1-Sinus floor elevation, when crestal and when lateral?
2-Densah lift as a paradigm shift in sinus floor elevation.
3-Common complications and how to manage them
