Abstract
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.
