A distance member (1) is designed so as to make possible a cemented superstructure in the jaw and can be fastened to the implant in the jaw by means of a screw member. The distance member has a prefabricated external shape which is individually adapted to the respective dental situation in question for the purpose of rendering unnecessary substantial shape modification work in connection with construction of the superstructure in the jaw. The prefabricated shape has a shelf-shaped projecting part located between the upper and lower parts of the distance member and the distance member is designed with an internal counterholder which prevents torque being transmitted from the tool to the implant.
L'invention concerne un écarteur (1) conçu de manière à recevoir une superstructure cimentée dans la mâchoire et pouvant être fixé sur un implant par une vis. L'écarteur a une forme externe préfabriquée adaptée à chaque situation dentaire, ce qui évite de modifier ultérieurement sa forme en fonction de la superstructure fixée dans la mâchoire. La forme préfabriquée présente une partie saillante tubulaire située entre les parties inférieure et supérieure de l'écarteur et l'écarteur comporte un dispositif de contre-poussée intérieure qui empêche le transfert du moment de rotation de l'outil à l'implant.
