Maxillary sinus expansion and atrophy can be difficult to overcome for patients who require functional dental prostheses. One solution for this problem is sinus augmentation and implant placement. Patients are evaluated and diagnosis is ascertained, leading to development of a treatment plan and surgical strategy. The surgeon decides on a surgical technique and grafting material, based on ultimate success, stability, and function as they relate to the goals. Complications can occur during an operation or during the postoperative healing phase. Dealing with these complications can be challenging; however, solving these problems positively affects the overall outcome and success.
