Dental component with through hole

A dental component for being mounted to a dental implant comprising:

• an apical side and a coronal side,
• a first hole substantially extending along a first axis, the first hole having an end region away from the apical side,
• a second hole substantially extending along a second axis, an entrance to the second hole being located coronally to the end region of the first hole,
• wherein the first hole and the second hole are formed to intersect each other creating an angulated channel,
• wherein the first axis and the second axis are inclined with respect to each other,
• wherein at least a part of the end region of the first hole is kept as part of the angulated channel,
• wherein in a cross-section extending along the first axis, a profile of the end region comprises multiple curved concave portions including a first curved concave portion having a first diameter and a second curved concave portion having a second diameter, and
• wherein the first diameter is greater than the second diameter and the first diameter is closer to the apical side along the first axis than the second diameter.

A method of designing a virtual dental component using CAD/CAM, the method comprising the steps:

• providing geometric data of a dental component,
• creating a first hole geometry in the dental component, wherein the first hole extends substantially along a first axis the first hole having an end region away from the apical side,
• creating a second hole geometry in the dental component, wherein the second hole extends substantially along a second axis, an entrance of the second hole being located coronally to the end region of the first hole,
• wherein the first hole and the second hole are created to intersect each other for creating an angulated channel,
• wherein the first axis and the second axis are inclined with respect to each other,
• wherein at least a part of the end region of the first hole is kept as a part of the angulated channel,
• wherein in a cross-section extending along the first axis, a profile of the end region comprises multiple curved concave portions including a first curved concave portion having a first diameter and a second curved concave portion having a second diameter, and
• wherein the first diameter is greater than the second diameter and the first diameter is closer to the apical side along the first axis than the second diameter.
