3. The dental prosthesis ( 100 ) according to claim 2 , characterized in that the connecting sleeve ( 140 ) can be aligned coaxially with the abutment ( 112 ) in the internal guide ( 122 ) arranged in the tooth part ( 120 ), wherein either the lower annular surface ( 147 ) of the connecting sleeve ( 140 ) terminates axially at or above an upper end ( 112 a ) of the abutment ( 112 ), or the connecting sleeve ( 140 ) is surrounded by the abutment ( 112 ), and the upper annular surface ( 146 ) of the connecting sleeve ( 140 ) terminates at or below the upper end ( 112 a ) of the abutment ( 112 ).
4. The dental prosthesis ( 100 ) according to claim 3 , characterized in that the closure body ( 130 ) has an external thread ( 131 ) and the connecting sleeve ( 140 ) has at least one internal thread ( 141 , 142 ) in order to releasably lock the closure body ( 130 ) within the internal guide ( 122 ) arranged in the tooth part ( 120 ).
5. The dental prosthesis ( 100 ) according to claim 4 , characterized in that the abutment ( 112 ) has an external thread ( 119 ) for engagement in at least one internal thread ( 141 , 142 ) of the connecting sleeve ( 140 ) in order to releasably connect the dental implant ( 110 ) to the connecting sleeve ( 140 ).
6. The dental prosthesis ( 100 ) according to claim 4 , characterized in that a collar section ( 123 ) of the tooth part ( 120 ) is arranged between the connecting sleeve ( 140 ) and the abutment ( 112 ) of the tooth implant ( 110 ) in order to releasably connect the tooth part ( 120 ) and the dental implant ( 110 ) to one another by the connecting sleeve ( 140 ).
7. The dental prosthesis ( 100 ) according to claim 4 , characterized in that the closure body ( 130 ) has an inner recess ( 136 ), for receiving a core element ( 137 , 138 ).
