Horizontal bone defects are a common consequence of tooth extraction, primarily due to the physiological resorption of the alveolar ridge. To enable successful implant placement, guided bone regeneration (GBR) with non-resorbable barrier membranes is often required. However, traditional methods involving titanium meshes are associated with relatively high rates of complications. With the advent of advanced customized jetting (ACJ) technology, zirconia barriers can be designed with a tailored inner layer microstructure, offering significant potential for GBR applications. In this series of studies, we evaluated the mechanical properties and biosafety of 3D-printed zirconia barriers, with supporting evidence derived from animal studies. The customized zirconia barriers demonstrated excellent clinical and histological performance. Notably, even in cases of premature exposure, the barriers showed no signs of infection. These findings highlight their effectiveness and safety in GBR procedures. The preliminary results suggest that 3D-printed zirconia barriers, with their customizable features and promising outcomes, represent a valuable innovation for enhancing bone regeneration practices.
