Telescopic crowns


Telescopic technique is used e.g. for shockabsorbing or the transmission of highly mechanical forces. In dental technology, telescopes are used as retaining elements. The advantage of telescopic dentures is an easy repair proposition after the extraction of a supporting tooth although we may have to look for other technical solutions in the case of large abutment divergences. Another disadvantage is a higher loss of dentine material in the supporting teeth due to preparation (approx. 1.8 mm) to obtain a better result of the double crowns from an aesthetic point of view. In any case, a shoulder preparation is the best precondition.
