Buccal Fat Pad vs. Palatal Rotation Scarf Grafts for Soft Tissue Management Around Zygomatic Implants

Plain-language summary
Over the past 20 years, the demand for oral rehabilitation among edentulous patients has steadily increased. Traditionally, individuals with edentulous maxillae were treated using removable complete dentures. However, these often result in poor patient satisfaction due to instability and functional limitations. Dental rehabilitation with implants in the maxillary arch presents unique challenges, primarily due to the anatomical complexity of the maxilla and the need for adequate residual ridge dimensions for successful implant placement.
Following the extraction of maxillary teeth, patients experience rapid and progressive alveolar bone loss in both vertical and horizontal dimensions. This resorption is largely attributed to the absence of teeth and periodontal ligament fibers support, which are essential for transmitting mechanical forces that maintain bone homeostasis. In addition, the loss of maxillary molars accelerates pneumatization/expansion of the maxillary sinus, further reducing available bone volume. Contributing factors such as ill-fitting dentures and systemic health conditions can exacerbate this process, complicating implant placement even further.
To overcome these limitations, oral and maxillofacial surgeons have developed a range of advanced techniques, including tilted implants, sinus floor elevation, short implants, pterygoid implants, and most notably, zygomatic implants. Zygomatic implants bypass the atrophic alveolar ridge entirely by anchoring into the dense zygomatic bone, offering a reliable solution for patients with severely resorbed maxillae who are not candidates for conventional implant therapy.
