Dental implant component

A wax-receiving, fabrication-intermediate component of a dental prosthesis or a core part of a dental prosthesis, comprising:

• a base section having a proximal end comprising means for engagement with a support end of a support component of a dental implant system, a distal end being spaced in an axial direction from the proximal end and presenting a distal top cross-sectional area having a transverse dimension, and a lateral surface extending from the distal end towards the proximal end;
• an elongate post section having an outer post surface, an axial dimension, a transverse dimension and a cross-sectional area, said elongate post section projecting in the axial direction distally from the distal end of the base section, wherein the transverse dimension of the post section is substantially less than said transverse dimension of the distal end of the base section, so that a step surface is thereby formed by the distal end of the base section, wherein said step surface is larger than the cross-sectional area of the post section at the distal end;
• and
• an outer wax-receiving surface consisting of said lateral surface of the base section, said step surface of the distal end and a part of said post surface from a point where the post projects from the distal end to a more distal point along the axial dimension of the post section wherein the more distal point is proximal to the most distal point,
• wherein the wax-receiving component is made entirely from a non-burnout material in order to remain intact in a lost-wax casting process and form part of the dental prosthesis or core part of the dental prosthesis.

A mold cavity forming assembly for use in the fabrication of a dental prosthesis or a core part of a dental prosthesis by lost-wax casting, comprising:

• (i) a wax-receiving component, made at least partly from a burnout material and comprising:
• a base section having a proximal end comprising engagement means for engagement with a support end of a support component of a dental implant system, and a distal end presenting a presenting a distal top cross-sectional area having a transverse dimension, and
• an elongate post section projecting distally from the distal end of the base section, said post section having a transverse dimension which is substantially less than said transverse dimension of the distal end, thereby providing a step at the distal end of the base section, wherein the base section and the post section provide an outer surface area;
• and
• (ii) a wax pattern in the form of a tooth applied on at least a part of said outer surface area, wherein at least a part of the post section projects distally from the wax pattern.
