FIGS. 1A , 1B and 1C are diagrams illustrating an abutment for implant according to an embodiment of the invention, respectively; -
FIGS. 2A , 2B and 2C are diagrams illustrating an abutment for implant according to another embodiment of the invention, respectively; and -
FIGS. 3A , 3B and 3C are diagrams illustrating a material of an abutment for implant according to another embodiment of the invention, respectively. - Hereinafter, embodiments of the invention will be described in detail with reference to the accompanying drawings.
- An abutment for implant according to each embodiment of the invention is for producing a final abutment which connects a fixture embedded in the gum to a crown forming an external form of an artificial tooth.
-
FIGS. 1A , 1B and 1C are diagrams illustrating an abutment for implant according to an embodiment of the invention, respectively. - As illustrated in
FIGS. 1A , 1B and 1C, anabutment 10 for implant according to the embodiment comprises abody 100 having a cylindrical shape, aninstallation portion 200 which is integrally formed with an end of thebody 100 and serves as a portion to install thebody 100 in a processing device or in a jig when a customized abutment (that is, a final abutment) is produced by processing thebody 100, acombination portion 300 formed at the other end of thebody 100 so as to be combined with a fixture, a threadedportion 400 formed to penetrate through theinstallation portion 200 and to pass through a portion of thebody 100 so that a fixing screw can be inserted into the threaded portion and thus thebody 100 is fixed to the processing device or the jig, and acoupling hole 500 which is formed to penetrate through thebody 100 and thecombination portion 300 in a longitudinal direction of thebody 100 so that a coupling unit (not shown) used to couple thebody 100 to the fixture can be inserted into thecoupling hole 500. - The
installation portion 200 is tapered to an outside portion of thebody 100, that is, from thebody 100 to an end of theinstallation portion 200. Thus, theinstallation portion 200 is taped as the sectional surface 21 is far from thebody 100. - Thereby, an external diameter of the
installation portion 200 is changed from thebody 100 to the end of theinstallation portion 200. For example, as shown inFIGS. 1A and 1B , the external diameter ofinstallation portion 210 decreases from thebody 100 to the end of theinstallation portion 200. - The
installation portion 200 further comprises a sectional surface 210 (that is, a cut portion) used for positioning when theinstallation portion 200 is coupled to the processing device or the jig. Thesectional surface 210 is formed by cutting a part of theinstallation portion 200. Thesectional surface 210 is formed at a portion of a side of theinstallation portion 200. - Alternatively, the

installation portion 200, that is, a surface (for example, a bottom surface) of theinstallation portion 200 has a polygonal shape or a letter D shape, and thus, a planar shape of theinstallation portion 200 is also a polygonal shape or a letter D shape. In theinstallation portion 200, the bottom surface of theinstallation portion 200 is opposite a surface contacting to thebody 100. - The threaded
portion 400 has threads corresponding to threads of a fixing screw. - As described above and shown in
FIG. 1( c), the threadedportion 400 is formed by penetrating through a portion of thebody 100 as well as theinstallation portion 200 in the longitudinal direction of thebody 100. Thereby, the threadedportion 400 is formed at theinstallation portion 200 and thebody 100. - As described above and shown in
FIG. 1( c), thecoupling hole 500 is formed by penetrating through a portion of thebody 100 as well as thecombination portion 300. Thereby, thecoupling hole 500 is formed at thecombination portion 300 and thebody 100. -

combination portion 300 a is formed at the other end of thebody 100 a so as to be combined with the fixture. - The
recess portion 600 a is formed between thebody 100 a and theinstallation portion 200 a to provide aninstallation reference plane 700 a of thebody 100 a when thebody 100 a is fixed. - Thereby, a portion of the
installation portion 200 a is separated from thebody 100 a by therecess portion 600 a. - Unlike the
installation portion 200 ofFIG. 1 , theinstallation portion 200 of the embodiment has the same external diameter as a position of theinstallation portion 200 a is changed from thebody 100 to the end of theinstallation portion 200 a along the longitudinal direction of thebody 100 a. - The threaded
portion 400 a is formed to penetrate through theinstallation portion 200 a and to pass through to a midway portion of thebody 100 a in the longitudinal direction of thebody 100 a so that a fixing screw used to fix thebody 100 to the processing device or the jig may be inserted into the threadedportion 200 a. - As described above and shown in
FIG. 2( c), the threadedportion 400 a is formed by penetrating through a portion of thebody 100 a as well as theinstallation portion 200 a and, thereby, the threadedportion 400 a is formed at theinstallation portion 200 a and thebody 100 a. - The
coupling hole 500 a is formed to penetrate through thebody 100 a and thecombination portion 300 a along the longitudinal direction of thebody 100 a so that a coupling unit used to couple thebody 100 a to the fixture may be inserted into thecoupling hole 500 a. - Thereby, as described above and shown in
FIG. 2( c), thecoupling hole 500 a is formed by penetrating through a portion of thebody 100 a as well as thecombination portion 300 a. Thus, thecoupling hole 500 a is formed at thecombination portion 300 a and thebody 100 a. - The
