[Use of the Preci-Horix attachment in anchoring an overlay denture]

In the case report the overdenture prosthesis replacing the subtotal edentulousness is fixed by a Preci-Horix anchorage of individual design built on the tooth roots. The matrix portion of the anchorage was built in situ into the tooth plate of the denture. This aimes at preventing the disadvantageous overloading effect of the position change due to initial sinking of the denture on the support tooth.
