[Is the telescope system still reasonable?]

Parallel milled abutments in partial dentures are the anchors of the so called telescoping system. Excellent function, easy cleaning and the possibility of modification on the case at a later date - if further losses of teeth should occur - are the great advantages of this design. The application of this suitable attachment seems to be limited by economic considerations and patients' desire for fixed brigdework. The state of the art is presented and proved by pretentious case-reports.
