Mono or polycrystalline alumina-modified hybrid ceramics

- Mono or polycrystalline alumina particles were added to a dental porcelain.
- Particle coating was carried out by heat treatment of a silica precursor.
- The addition of monocrystalline particles yielded a more translucent hybrid ceramic.
- Polycrystalline alumina particles worked as nanoclusters.
- Glass bridging from porcelain to alumina particles suggested chemical interaction between the two phases.
