Mesh on RPD Framework

Unlike open lattice work which offers large spaces between each strut, mesh is essentially a thin sheet of metal with very small perforated holes. It covers virtually the same area of the residual ridge as would be covered by the struts of lattice work. The meshwork is embedded in the acrylic and the two materials adhere to each other through mechanical retention.

The primary indication for meshwork is where there is limited inter-occlusal space (vertical height) and struts would interfere with ideal teeth placement. Meshwork, being far thinner, allows more space for ideal teeth arrangement. However, due to limited strength and higher fracture rates, meshwork is not a recommended design for cases with adequate vertical space.
