Inadequate bone volume is a fundamental problem encountered in the rehabilitation of the edentulous posterior maxilla with implant-supported prostheses. The bone ready for implant placement may be limited by the presence of the maxillary sinus together with loss of alveolar bone height, and it may be increased by augmentation. With age or other different factors, the patient may lose the volume of the upper jaw bone in the molars. As soon as the surgeon is faced with such a situation, he is obliged to perform the filling of the sinus floor with a bone graft.
A result of implant success is the amount and quality of the bone where the implant is to be fixed. The upper back jaw has traditionally been one of the most challenging areas to actively place dental implants due to inadequate bone volume and quality and the close closeness to the sinus. If you’ve lost bone in that area due to reasons such as periodontal infection or tooth loss, you may be left without enough bone to place implants.
Sinus lift operation can help fix this problem by lifting the sinus floor and increasing bone for the placing of dental implants. Many techniques can be used to raise the sinus and support for new bone to form. In a straightforward method, a cut is made to expose the bone. Then a small circle is cut into the bone. This bony piece is lifted into the sinus cavity, much like a trap door, and space underneath is filled with bone graft element. Your periodontist can describe your options for graft materials, which can regenerate lost bone and tissue.
Knowing sinus lift surgery has been shown to significantly increase your chances for strong implants that can last for years to come. Several patients feel minimal trouble during this procedure.
