Definitions

  • - fig. 6 shows a perspective view of a model of the prepared tooth
  • - fig. 9 also shows a part of a restoration and a part of a manufacturing tool.
  • a simple coping restoration is characterised by the uniform thickness of the complete restoration. This form is relatively simple to accomplish since it is an offset of the preparation surface. The reduction of the crown is uniform and will give the dental technicians an excellent base for the porcelain work. When a tooth is in bad condition, it is sometimes necessary to remove quite a lot of the tooth. When a simple coping is made for this type of preparation, there will be a very thick and uneven layer of porcelain which builds up the crown. As the porcelain is much weaker than the coping, or core, this will affect the strength of the final restoration. It may also be aesthetically unattractive. In some cases when modern leucit porcelain is used it is not even possible to use the simple coping because it locally will require a thickness of the porcelain layer outside of the manufacturer specification. It is also time consuming to build a crown which requires a lot of porcelain as the different layers may have to be burned after each other in a furnace.
  • a band of the coping material is visible all the way around the crown, and
  • the restoration parameters hi, h2, h3, h4, h.5, gl, g2 comprise a restoration thickness parameter h5, intended to assume a value indicating the desired thickness of at least part of the restoration 50.
