Abstract: An abutment fixing apparatus comprising a holder, a body connected to the body, and at least one installation recess into which at least one abutment is inserted. The abutment fixing apparatus further comprises at least one fixing unit connected to the body and fixing the abutment at a desire position of the at least one installation recess, and the at least one fixing unit moves the abutment in a direction equal to an insertion direction of the abutment into the at least one installation recess or applies a pressure to an entire external surface of a portion of the abutment, which is covered with the at least one fixing unit, to fix the abutment at the desired position of the at least one installation recess.
