It's an assembly
An abutment having a first mounting structure defining a first undercut,
With a superstructure fixed to the abutment
The superstructure has a thermoplastic implant arranged in contact with the first mounting structure, the thermoplastic material is liquefiable by mechanical vibration, and the first mounting structure. It is fluid to the body, whereby after resolidification, the superstructure is secured or secured to the abutment by a mating connection by the first undercut.
The superstructure has a second mounting structure with a second undercut, further provided with a connecting component having a thermoplastic material, the thermoplastic material being liquefiable by mechanical vibration. And, it is flowable with respect to the first mounting structure and the second mounting structure, whereby after resolidification, the superstructure is infused with the thermoplastic material. An assembly that is secured to the abutment by an undercut and a mating connection by the second undercut. The assembly of claim 1, wherein the superstructure is selected from the group consisting of crowns, bridges, dentures, facial prostheses, and orthodontic anchors. The assembly according to claim 1 or 2, wherein the thermoplastic implant, or a connecting component having the thermoplastic material, is a thermoplastic pin or comprises a thermoplastic ring. The thermoplastic implant, or connecting component with the thermoplastic material, is a thermoplastic pin, the abutment has a channel, the superstructure has a pocket, and the superstructure is on the abutment. The assembly according to claim 3, wherein the pocket can be accessed by the channel and the thermoplastic pin can be introduced into the pocket after being placed in the pocket. The assembly of claim 4, wherein the pocket comprises an empty space formed in a cruciform shape. The assembly of claim 4 or 5, wherein the first mounting structure has an undercut around the channel formed in a cruciform shape. The assembly of any one of claims 4-6, wherein the channel is located within the apical end of the superstructure. The assembly of any one of claims 4-7, wherein the channel is located on the lingual, buccal, or labial side. One of claims 1 to 3, wherein the thermoplastic implant, or a connecting component having the thermoplastic material, is a cup fitted between the first mounting structure and the second mounting structure. The assembly according to item 1. 9. The assembly of claim 9, wherein the cup comprises an apical ring, a crown ring, and a stick connecting the apical ring and the crown ring. 10. The assembly of claim 10, wherein the abutment and / or the superstructure comprises a groove having at least one serrated surface, the stick fitting into the groove. 10. The assembly of claim 10 or 11, wherein the abutment has a recess and the apical ring of the thermoplastic implant or of a connecting component having the thermoplastic material fits into the recess. The assembly according to any one of claims 1 to 3, wherein the thermoplastic implant, or a connecting component having the thermoplastic material, comprises a pin having a head region. 13. The assembly of claim 13, wherein the head region has an energy-inducing structure at its coronal end. The assembly according to any one of claims 1 to 14, wherein the connecting component having the thermoplastic material is fixed to the abutment. The abutment forms a facing surface for liquefaction of the thermoplastic implant or a connecting component having the thermoplastic material, the facing surface for the initiation of melting and the liquefied thermoplastic material. The assembly according to any one of claims 1 to 15, comprising an energy-inducing structure for guiding the flow of the above. The assembly according to any one of claims 1 to 16, wherein the thermoplastic implant, or a connecting component having the thermoplastic material, is further suitable for fixing the fixture of the abutment. A set including the assembly according to any one of claims 1 to 15, a tool for applying ultrasonic vibration energy to a thermoplastic material, and an intermediate component, wherein the intermediate component is the upper portion. The superstructure or the abutment has an apical end having a shape suitable for the structure or the abutment and a crown side end suitable for binding to the tool, and the superstructure or the abutment is an individual. A set that is unique to the patient . 18. The set of claim 18 , wherein the mass center of the abutment is aligned with respect to a central axis defined by the tool.
