A new apparatus to measure the hydrostatic pressures developed during the cementation of dowel-retained prostheses has been developed and is described. The initial results obtained using this apparatus have been shown to vary from zero if the dowel is coated with cement, to 1.1 times 104 kN/m2 when cement is placed into the prepared hole for an optimally fitting dowel. Avenues of further research using this apparatus are mentioned.
