Prefabricated CAD/CAM zirconia membrane versus contour augmentation with early implant placement in the anterior maxilla: a randomized controlled clinical trial
Customized CAD/CAM zirconia membranes achieved horizontal bone augmentation comparable to conventional collagen membranes when used for simultaneous GBR during early implant placement, indicating that customized rigid barriers may represent a predictable alternative for horizontal ridge augmentation while offering pote...
