Embodiment Construction

[0013] figure 1 An embodiment of a screw according to the invention is shown, which is designed for connection with a threaded hole of a dental implant. In this embodiment, the threaded member is a healing abutment (1) designed to connect with an implant to control the growth of soft tissue after surgery. The healing abutment (1) comprises a head (2) and a threaded body (3). The threaded body (3) comprises a main threaded region (4) followed by a threaded end (5) arranged in decreasing width. The threads of the thread ends (5) arranged to decrease in width are preferably identical to the threads of the main thread zone (4); in other words, the threads between the two zones (4, 5) are continuous. Alternatively, the threads of the threaded end (5) arranged to decrease in width may differ from the threads of the main threaded region (4), provided that the threads of the threaded end are compatible with the threads of the implant (in other words, provided that when There is no ...

Abstract

A threaded element (1), destined for connection to a threaded orifice (7) of an implant (6), comprises a principal threaded zone (4) terminating in a threaded tip having a decreasing width (5). The presence of the threaded tip having a decreasing width (5) permits achievement of two effects: through the decreasing width thereof the tip of the threaded element (1) is inserted with greater facility within the threaded orifice (7), even should the threaded element (1) enter very out of true within the threaded orifice (7); being threaded, the tip of the threaded element (1) commences screwing into the threaded orifice (7) prior to the principal threaded zone (4), as a result whereof the threaded element (1) tends to straighten up unaided as it is screwed in. The threaded element (1) according to the invention may be a prosthesis screw, a closure screw, an implant-bearing screw, a healing abutment, a transepithelial abutment, etc.

Description

technical field [0001] The present invention relates to a threaded member (particularly to the threaded system used) which is connected to an implant through its threaded hole in order to seal or seal the implant or to connect the implant to a device such as a prosthetic device. External parts are connected. Background technique [0002] An implant is a part that is installed in the patient's bone and whose ultimate function is to effectuate the connection of the prosthesis. To achieve this, the implant usually has roughly the same shape as a screw, with a head and a threaded end. The threaded end is designed to connect to the bone, while the head is the area where the prosthesis and other parts involved in the surgery to install the implant connect. The implant is also provided with a threaded hole designed to enable a connection with a threaded member for closing or sealing the implant or allowing the implant to be connected to an external part such as a prosthesis. For...
