Threaded connection between a male part (2) and a female part (1), particularly between a screw and a dental implant, both parts (1, 2) fitted with a thread profile with spires, whereby the thread step (4b) of the thread profile of the male part (2) is different to the thread step (4a) of the thread profile of the female part (1), obtaining a controlled gap (3) between both parts. According to the invention, one of the two parts (1, 2) has a variable thread step. Therefore, the threaded connection between both parts (1, 2) presents a gap (3) that varies in a non-linear manner. By appropriately adjusting the specific design of the thread steps, it is possible to control the stress distribution throughout the threaded connection in accordance with the interests of the application.
L'invention concerne un raccordement fileté entre un élément mâle (2) et un élément femelle (1), en particulier entre une vis et un implant dentaire, les deux éléments (1, 2) présentant un profil de filetage constitué de spires, le pas de filet (4b) du profil de filetage de l'élément mâle (2) étant différent du pas de filet (4a) du profil de filetage de l'élément femelle (1), ce qui permet d'obtenir un espace (3) entre les deux éléments. Selon l'invention, un des deux élément (1, 2) présente un pas de filet variable. Par conséquent, le raccordement fileté entre les deux éléments (1, 2) présente un espace (3) qui varie de manière non linéaire. Par ajustement de manière approprié de la conception spécifique des pas de filet, il est possible de contrôler la distribution de tension à travers le raccord fileté conformément aux intérêts de l'application.
