1. A mixing tip for a dispenser, comprising: a lower casing configured to be connected to the dispenser and to receive a silicone base material and a curing agent;an upper casing coupled to the lower casing and including a discharge pipe through which an impression material having a desired mixing ratio of the silicone base material and the curing agent is discharged to the outside; anda mixer disposed between the lower casing and the upper casing to mix the silicone base material with the curing agent,wherein the mixer comprises: a mixing plate disposed between the lower casing and the upper casing and having a predetermined surface area;a shaft-fitting pipe extending downward from the mixing plate and configured to be fitted over a drive shaft of the dispenser to be rotated therewith; anda path control rib extending downward from an outer peripheral edge of the mixing plate to control flow paths of the silicone base material and the curing agent; andwherein the lower casing comprises: a body comprising an upper casing-fitting ring formed at an outer peripheral edge thereof and coupled to the upper casing and an inner fitting ring spaced apart from the upper casing-fitting ring by a predetermined interval and extending from the body;a base material supply pipe extending downward from a bottom surface of the body to receive the silicone base material and to discharge the silicone base material into a buffer space defined between the path control rib and the mixing plate; anda curing agent supply pipe spaced apart from the base material supply pipe to receive the curing agent and to discharge the curing agent into a space defined between the path control rib and the inner fitting ring so as to guide the curing agent to bypass the buffer space. 2. The mixing tip for a dispenser according to claim 1, wherein the curing agent supply pipe has at an inner surface thereof an inclined guide surface for guiding the curing agent introduced from the dispenser toward the inner fitting ring. 3. The mixing tip for a dispenser according to claim 2, wherein the inner fitting ring has at an inner surface thereof a curing agent guide groove having a predetermined depth, the curing agent guide groove being connected to an upper end of the curing agent supply pipe to guide the curing agent toward the outside of the path control rib. 4. The mixing tip for a dispenser according to claim 1, further including a mixing pipe disposed between the mixing plate and the discharge pipe, the mixing pipe being in fluid communication with the discharge pipe. 5. The mixing tip for a dispenser according to claim 4, wherein the path control rib is configured to guide the curing agent directly into the mixing pipe, and wherein the buffer space is configured to accumulate the silicone base material before the silicone base material is introduced into the mixing pipe. 6. The mixing tip for a dispenser according to claim 4, the path control rib is configured to guide the curing agent and the silicone base material towards the mixing pipe through separate flow paths. 7. A mixing tip for a dispenser, comprising: a lower casing configured to be connected to the dispenser and to receive a silicone base material and a curing agent;an upper casing coupled to the lower casing and including a discharge pipe through which an impression material having a desired mixing ratio of the silicone base material and the curing agent is discharged to the outside; anda mixer disposed between the lower casing and the upper casing to mix the silicone base material with the curing agent,wherein the mixer comprises: a mixing plate disposed between the lower casing and the upper casing and having a predetermined surface area; anda shaft-fitting pipe extending downward from the mixing plate and configured to be fitted over a drive shaft of the dispenser to be rotated therewith, andwherein the lower casing comprises: a body comprising an upper casing-fitting ring formed at an outer peripheral edge thereof and coupled to the upper casing and an inner fitting ring spaced apart from the upper casing-fitting ring by a predetermined interval and extending from the body;a base material supply pipe extending downward from a bottom surface of the body to receive the silicone base material and to discharge the silicone base material into a buffer space under the mixing plate; anda curing agent supply pipe spaced from the base material supply pipe to receive the curing agent and to discharge the curing agent along the inner fitting ring without introducing the curing agent into the buffer space. 8. The mixing tip for a dispenser according to claim 7, further including a mixing pipe disposed between the mixing plate and the discharge pipe, the mixing pipe being in fluid communication with the discharge pipe. 9. The mixing tip for a dispenser according to claim 8, wherein the mixing plate is configured to guide the curing agent directly into the mixing pipe.
