Abstract
An enossal implant for firmly seating a tooth replacement includes a fastng head on a metal implant post which is threadably secured into a base element, which is either a base body or a metal spacer threaded into the base body. To prevent twisting between the post and the base element, the base element has a recess for receiving an intermediate retaining ring formed of a plastic material which has smooth faces, and the ring is entrapped between a shoulder in the base element and a shoulder on the implant post and interlocking depressions are formed in either the recess and/or the shoulder of the post so that during threading-in of the post, the retaining ring is deformed to fill the recesses to restrain twisting therebetween.
