三种评价方法测量的硅橡胶薄膜厚度(x±s, /μm)

Thicknesses of polyvinyl siloxane replicas measured by three methods in each component of removable partial denture (x±s, /μm)

Items	CSM group	TAS group	TAP group	P
* P < 0.05, vs. CSM group. CSM, cross sectional measurement; TAS, three-dimensional analysis on stone cast; TAP, three-dimensional analysis on polyether cast.
