Abstract
According to one example, a holding device system including a two-part holding frame having a blank holder coupled to a main frame is disclosed. The two-part holding frame can define a processing space and a fixation space. The holding device system can further include at least one fixation element having a head positioned within the fixation space and a threaded shaft extending within and engaged with a bore of the two-part holding frame. In one example, when the blank holder is coupled to the main frame, the at least one fixation element is unable to be removed from the two-part holding frame.
Claims20
A holding device system for holding an abutment blank, comprising:
- a two-part holding frame, including:
- a main frame;
- a blank holder coupled to the main frame, the blank holder defining at least one fixation bore, wherein the two-part holding frame defines a processing space and a fixation space, the processing space defined above a top surface of the blank holder and the fixation space defined below a bottom surface of the blank holder;
- and
- at least one fixation element having a head and a threaded shaft configured to extend through at least one fixation bore and couple with the abutment blank,
- wherein, when the at least one fixation element is engaged with the blank holder, the head is positioned within the fixation space and the at least one fixation element can transition between a first floating position and a second engaged position.
A method for holding an abutment blank for machining, the method comprising:
- providing a two-part holding frame, including a blank holder coupled to a main frame, the two-part holding frame defining a processing space and a fixation space, wherein at least one fixation element has a head positioned within the fixation space and a threaded shaft extending within a bore of the blank holder;
- and
- affixing the abutment blank to the two-part holding frame, the affixing including:
- positioning the abutment blank such that an engagement bore along a contact end of the abutment blank is aligned with the bore of the blank holder, the abutment blank having an implant interface opposite the contact end;
- and
- applying a rotational force to the head of the at least one fixation element such that the threaded shaft extends from the bore of the blank holder and engages with the engagement bore of the abutment blank to affix the abutment blank to the two-part holding frame.
A holding device system for holding an abutment blank, comprising:
- a two-part holding frame, including a blank holder coupled to a main frame, the two-part holding frame defining a processing space and a fixation space;
- and
- at least one fixation element having a head positioned within the fixation space and a threaded shaft extending within a bore of the blank holder, the at least one fixation element configured to transition from a first floating position to a second engaged position,
- wherein, at the first floating position, a distal end of the threaded shaft is at least one of substantially flush with the at least one fixation bore or recessed within the at least one fixation bore, and
- wherein, at the second engaged position, the distal end of the threaded shaft extends beyond a top surface of the blank holder to engage with the abutment blank.
