Varying amounts of bone resorption can occur following tooth loss, and this can lead to implant placement problems due to a lack of an alveolar ridge with suitable osseous dimensions. There are many techniques for bone regeneration and many types of barriers, including polytetrafluoroethylene, collagen, and titanium meshes. The present case report describes the use of a customized CAD/CAM zirconia barrier for vertical ridge augmentation. A bone height gain of 12 mm was observed, as well as 8 mm of width. Subsequent histologic analysis revealed an excellent bone quality, allowing successful implant placement.
