Abstract
A dental implant includes a body and a thread. The body has a central axis, a coronal end, and an apical end. The thread is coupled to the body. The thread has a coronal facing surface, an apical facing surface, and a crest surface positioned between the coronal facing surface and the apical facing surface. The coronal facing surface of the thread has a plurality of steps formed therein.
Claims42
A method of making a dental implant, the method comprising:
- forming a cutter using a grinder, the grinder having a grit between about 50 and about 200;
- using a computer guided cutting machine and the formed cutter, cutting a blank of material to form the dental implant such that the formed dental implant has a thread that is coupled to a body, the body having a central axis, a coronal end, and an apical end, the cutting the blank of material to form the thread including making a series of stepped cuts about the blank of material, each of the series of stepped cuts forming a respective step in the thread of the dental implant and a portion of the thread, each of the respective steps in the thread of the dental implant having a tread and a riser.
A method of making a dental implant, the method comprising:
- forming a cutter using a grinder, the grinder having a grit between about 50 and about 200, the formed cutter including a plurality of grooves caused by the grinder having a grit between about 50 and about 200;
- using a computer guided cutting machine and the formed cutter, cutting a blank of material to form the dental implant such that the formed dental implant has a thread that is coupled to a body, the body having a central axis, a coronal end, and an apical end, the cutting the blank of material to form the thread including making a series of stepped cuts about the blank of material, each of the series of stepped cuts forming a respective step in the thread of the dental implant and a portion of the thread,
- wherein the plurality of grooves of the cutter cause corresponding grooves to be formed in the formed dental implant.
A method of making a dental implant, the method comprising:
- forming a cutter using a grinder, the grinder having a grit between about 50 and about 200, the formed cutter including a plurality of grooves caused by the grinder having a grit between about 50 and about 200;
- using a computer guided cutting machine and the formed cutter, cutting a blank of material to form the dental implant such that the formed dental implant has a thread that is coupled to a body, the body having a central axis, a coronal end, and an apical end, the cutting the blank of material to form the thread including making a series of stepped cuts about the blank of material, each of the series of stepped cuts forming a respective step in the thread of the dental implant and a portion of the thread,
- wherein the plurality of grooves of the cutter cause corresponding grooves to be formed in at least a portion of a root surface of the thread, in at least a portion of a coronal facing surface of the thread, in at least a portion of an apical facing surface of the thread, in at least a portion of a crest surface of the thread, or any combination thereof.
