Hereinafter, forming a teeth mold after taking the impression is the same as described in Embodiment 1 , so the description thereon will be omitted.
[Embodiment 3] Fig. 9 is an assembled cross-sectioned view for showing an impression coping for implant treatments according to yet another embodiment of the present invention.
As shown in Fig. 9, an impression coping for implant treatments according to yet another embodiment of the present invention is related to the fixture 61 mounted into the alveolar bone, the abutment 51 the lower end part of which is screw-coupled to the fixture 61 and on the middle part of the outer circumference of which the middle boundary part 52 is formed, the auxiliary coping 61 having the engagement protrusion 56 formed on the lower part and coupled to the middle boundary part 52 to be detachably and elastically coupled to the abutment 51 , and a technology that takes an impression by covering an impression material of synthetic resin having fluidity over natural teeth adjacent to an implant treatment portion, which are substantially the same as the impression coping for implant treatments described in Embodiment 2 of the present invention so that the detailed descriptions on the structures and operations therefor will be omitted.
A screw opening 51a corresponding to a screw is formed in the abutment 51 in order that artificial teeth molded by the impression material can be fixed to the abutment 51 by the screw(not shown).
INDUSTRIAL APPLICABILITY
As described above, the present invention takes an auxiliary coping in a state fixed to an impression material upon taking a teeth impression, manufactures a prosthetic device in the same as the shape of natural teeth, and enables precise treatments in a designated position, and can enhance esthetic feelings in harmony of height and angle with adjacent natural teeth. Although the preferred embodiment of the present invention has been described, it will be understood by those skilled in the art that the present invention should not be limited to the described preferred embodiment, but various changes and modifications can be made within the spirit and scope of the present invention as defined by the appended claims.
