Effectiveness of reverse twin block with lip pads-RME and face mask with RME in the early treatment of class III malocclusion [PDF]

Progress in Orthodontics, 2019
Background The use of face mask for early treatment of class III malocclusion has proven to be successful, but its compliance and related dental side effects have always been a problem. To overcome this, a new approach has been suggested.

Structure and reactivity assessment of dioctahedral montmorillonite during provoked variable sequential cation exchange process via XRD modelling approach

Applied Surface Science Advances, 2023
The intrinsic cation exchange capacity (CEC) of clays is a crucial characteristic that offers a tool to assess their overall chemical properties. For the confinement of industrial and radioactive waste, clays are deployed as geological barriers, hence it
