Abstract
A dental abutment core with a prosthetic connection, a pillar and a shoulder located between the prosthetic connection and the pillar. The pillar has anti-rotational elements for preventing a custom body from rotating with respect to the dental abutment core. The pillar has a first portion adjacent to the shoulder, a second portion adjacent to the first portion, and a third portion farthest from the shoulder. A cross section of at least part of the first portion is circular and has an outer diameter which is lower than a cross section dimension of the second portion. The anti-rotational elements are located in the third portion. A method for manufacturing a dental abutment with such dental abutment core is also described.
Claims16
A dental abutment core for being used in an abutment for forming the gingival tissue around implants, the dental abutment core comprising:
- a prosthetic connection;
- a pillar comprising anti-rotational means for preventing a custom body from rotating with respect to the dental abutment core;
- a shoulder located between the prosthetic connection and the pillar, the shoulder being intended to be in contact with gingival tissue, wherein the shoulder comprises:
- a first base adjacent to the prosthetic connection and
- a second base having a cross section equal or greater than the first base;
- and
- a core axis perpendicular to the first base and the second base;
- wherein
- the pillar comprises a first portion adjacent to the shoulder, a second portion adjacent to the first portion, and a third portion farthest from the shoulder,
- a cross section of at least part of the first portion is circular and has an outer diameter which is smaller than a cross section dimension of the second portion,
- the second portion comprises a circumferential protrusion,
- a cross section dimension of the second portion is larger than a cross section dimension of the third portion,
- the anti-rotational means are comprised in the third portion, and
- the first portion comprises a first sub-portion adjacent to the shoulder and a second sub-portion with a circular and smaller cross section than the cross section of the first sub-portion.
A dental abutment core comprising:
- a prosthetic connection;
- a pillar comprising:
- a shoulder;
- a first portion adjacent to the shoulder;
- a second portion adjacent to the first portion;
- and
- a third portion farthest from the shoulder,
- wherein the shoulder comprises
- a first base adjacent to the prosthetic connection;
- and
- a second base having a cross section dimension equal or greater than the first base,
- wherein the first portion comprises
- a first sub-portion and
- a second sub-portion in which the first sub-portion of the first portion is circular and has an outer diameter which is smaller than a cross section dimension of the second portion,
- wherein the second portion comprises a circumferential protrusion having a cross section dimension larger than a cross section dimension of the third portion,
- wherein the third portion comprises an anti-rotational means, and
- wherein the second sub-portion of the first portion has a cross section which is smaller than the cross section of the first sub-portion of the first portion;
- a cap configured to rest on the circumferential protrusion of the second portion of the pillar when covering over the second portion and the third portion of the pillar;
- and
- a moulding apparatus configured to couple to the pillar at the prosthetic connector and the shoulder of the pillar.
