[Vertical movement of teeth following preparation for inlays with preservation of cavity walls].

Abstract

By means of an indirect measuring procedure applied to 24 teeth including molars and premolars the extent of the teeth's vertical motion has been established. During the first three days after the neutralisation of the antagonistic contacts upon cavity preparation the scale and speed of the axial movement of the teeth were found to be larger than on the following four days (0.102 greater than 0.059 mm). It is recommended to apply cast fillings with a replacement of the occlusive area as quickly after the wax mould as possible because of the diminished gap due to the motion of the teeth.
