DNA cross-linked hydrogel was used as a matrix for synthesis of gold nanoparticles. DNA possesses a strong affinity to transition metals such as gold, which allows for the concentration of Au ...

A 3D-printed template is therefore an acceptable and reliable alternative to traditional direct composite restoration of maxillary central incisors including fractured teeth and dental caries.

A 3D-printed template was fabricated using intra-oral scanning, CAD, virtual modeling and 3D printing as in the first case. Finally, the 3D-printed template was fabricated (Figure 8).
