Definitions
- the invention relates, on the one hand, to a method for securing a medical element in an implant, wherein first a connecting pin of the medical element is received in a receiving recess of the implant extending longitudinally into an interior of the implant, and a projection on at least one wing movable transversely to the longitudinal direction a medical element with a connecting pin, which can be received in a receiving recess of an implantable in a receiving bore in a bone implant implant, wherein the receiving recess is a clip element of the connecting pin with a radially outwardly facing recess in a lateral surface of the receiving recess is engaged extends longitudinally into an interior of the implant and the connecting pin extends a clip element having at least one transversely to the longitudinal direction of movable wings and at this a radially outwardly projecting projection has, which is engageable with a corresponding recess in a lateral surface of the receiving recess in engagement.
- medical elements can be fastened particularly gently in the bone using such methods.
- a sleeve-shaped implant with a simple closure cap is inserted into the bone.
- any medical element in the dental field in particular a replacement tooth, an impression post or a gingiva former can be used.
- the medical element can be easily and quickly connected to the receiving recess of the implant and also this connection can be very easily and quickly solve again.
- the clip connection according to the known methods or to the known medical elements must meet high requirements: on the one hand, it must be so easy to insert and detach that the implant firmly bonded to the bone is not excessively loaded in its longitudinal direction either by pressure or by tension. On the other hand, the force required to release the clip connection must remain constant at high and varying loads between the implant and the medical device over a long period of time - typically years to decades for replacement teeth.
- the invention has for its object to secure a medical element of the aforementioned type against unintentional release from the implant.
- the wing is then secured by curing a curable material in the receiving recess (9) against radial movement.
- the wing is in this way before the introduction of the securing element unrestricted radially movable and can be used accordingly with minimal effort in the implant.
- the wing can even be attached to the clip element so articulated that it does not generate any counterforce when inserted into the implant. Only by the cohesive connection with the cured mass, the clip element is fixed and secured in the desired position. The wing is then blocked against radial movement inwards and thus reliably and permanently prevents unintentional release of the medical element from the implant.
- the curable composition in the receiving recess is hardened with UV light.
- Working with UV-curable compositions is one of the standard techniques in dental technology and is thus particularly easy to use in this context.
- a variety of curable materials are available at low cost, which allow an individual adaptation of the inventive method to the individual case.
- the wing is additionally secured against radial movement by means of a securing element introduced into the clip element.
- a securing element introduced into the clip element.
- the use of such a securing element not only increases the durability of the securing of the medical element in the implant.
- it also allows - without curable mass - a provisional securing the medical element in the implant, for example, in laboratory operation.
- the securing element is preferably introduced into a passage opening extending from a proximal end of the connecting pin into the clip element.
- a continuous passage opening offers various options for the design of the method according to the invention and thus increases its variability.
- one end of a light-guiding element can be introduced into the bushing opening (14, 19, 27), the curable composition cured by shading the light-guiding element with UV light, and then the end of the light-guiding element severed, the severed end of the light-guiding element acting as a securing element in the clip element remains.
- the method is considerably simplified in that the end of the light-guiding element remains in the clip element after curing. An elaborate process monitoring to prevent sticking of the light-guiding element, is unnecessary, since even this effect is even desired to increase the connection stability.
- the securing element is provided with an external thread and in a corresponding Internal thread of the fürfiihmngsöffhung screwed into the clip member and / or set by means of an elastic locking ring in a radial opening in the passage opening in the longitudinal direction.
- the purely mechanical securing of the medical element simplifies handling on the one hand.
- the compounds obtained are insensitive to chemical aging processes compared to polymers.
- the handling of the implant system is further simplified because the end position of the securing element in the medical element according to the invention is defined clearly palpable during installation.
- a method according to the invention can be configured such that the securing element is releasably inserted into the clip element.
- a pin-shaped securing element can be inserted precisely into a cavity of the clip element such that a radial movement of the movable wing and thus an unintentional release of a particular only temporarily inserted into the implant medical element - for example, a cap, an impression post or a gingiva former - reliably avoided.
- such a curable composition which can be depolymerized, for example using a solvent, then the release of the medical element from the implant is further simplified.
- the implant is implanted in a bone with a medical element received therein.
- the medical element accommodated in the implant during implantation can be, for example, a handling element secured against unintentional loosening analogously to the above-described method, or else a closure or healing cap. This considerably simplifies the handling of the implant system. By implanting with inserted healing cap also the receiving recess of the implant is reliably protected from contamination.
- the implant for the laboratory adaptation of the medical element can be modeled in place instead of in a bone in a device.
- a device For example, one facilitates the jaw modeled device the laboratory adaptation in the context of adjacent teeth.
- the inclusion of the implant in a holding or handling element facilitates the all-round manual processing - cutting, coloring or layer by layer order other material - the medical element.
- the securing element can be introduced starting from the free end of the connecting pin in the clip element.
- a short, "from below" in the connecting pin to be inserted securing element may for example be integrated into the device and connected to a safety switch, that a machining of the medical element by means of electrically driven tools only after securing is possible.
- the medical element can be connected to a second medical element via a web, wherein the web is fixed to the medical element according to the invention by means of the securing element.
- the web can be fixed to the medical element according to the invention, for example by a circumferential collar or by individual radially projecting lugs on the securing element or by gluing with the securing element.
- the medical element can be secured in the implant by the respective above-described physical features according to one of the aforementioned methods.
