The need for a Sinus Lift Procedure (Sinus Augmentation) is dependent upon the anatomy of the maxillary jaw bone. To ensure the success of a dental implant in the maxillary arch, it is necessary to have at least 5mm of bone width and at least 7mm of bone height. A Sinus Lift Procedure aids in an attempt to provide the bone mass needed. The healing time of at least six months is required. After the area has healed, the implant process may begin.
