Abstract
More than half a century ago, the konus telescope crown (hereinafter referred to as konus) was developed by Körber. The konus is applicable to a wide variety of cases including before and after prosthetic treatment. In my opinion the konus is completely different from many other prosthetic methods. Other treatment methods cannot be carried out in a seamless manner, but the konus can. In Japan, however, the konus has not found a definitive role in the general and comprehensive dental care system, albeit its maintainability and predictability over the course of life after the treatment. In this paper, I rethink the essential clinical significance and value of the konus that had not been before discussed thoroughly in Japan. I would like to report my conclusion that the konus can be used as a general, inclusive, concrete and practical dental treatment system in comprehensive prosthetic treatment including before and after the prosthetic treatment.
