What is the meaning of Maxillary Sinus Augmentation?
Maxillary Sinus Augmentation is widely used term in Dental Techniques.
Maxillary sinus augmentation, also known as sinus lift or sinus elevation, is a dental technique used to increase the amount of bone in the upper jaw, specifically the area of the maxillary sinus. This procedure is performed when there is insufficient bone height in the posterior maxilla, usually due to tooth loss or bone resorption.
During the procedure, a small incision is made in the gum tissue to expose the underlying bone. Then, a small window is created in the bone, accessing the sinus cavity. The sinus membrane is gently lifted and a bone graft material, such as synthetic bone or the patient’s own bone, is placed in the space created. This graft material promotes new bone growth in the area, increasing the bone volume in the posterior maxilla.
Maxillary sinus augmentation is typically performed prior to dental implant placement in cases where the existing bone height is inadequate to support the implants. By adding bone to the sinus area, the dental professional can create a more stable foundation for the implant, increasing the chances of successful implant integration and long-term stability.
This dental technique requires careful planning, as the proximity of the maxillary sinus makes it important to prevent any damage to the sinus membrane. Pre-operative imaging, such as a cone beam computed tomography (CBCT) scan, is often used to evaluate the anatomy of the sinus and plan the procedure accordingly.
Overall, Maxillary sinus augmentation is a valuable dental technique that allows for the successful placement of dental implants in cases with insufficient bone height in the posterior maxilla.
