Tooth Morphology: Identifying the Adult Dentition

This video shows the ceramic 'build-up' stage of the production of a ceramic crown to restore a damaged tooth. In this video, ceramic powders are applied by brush to the substructure. The ceramic powders are fired to sinter them into a hard structure, and then refired and adjusted until the desired shape is achieved.

This video shows next stage of the production of a ceramic crown to restore a damaged tooth. In this video, the core of the tooth restoration (made from alumina) is milled using a CAD-CAM process. The porous structure is infiltrated under heat and pressure with a glass to give a strong substructure.

This video shows the ceramic 'stan and glaze' stage of the production of a ceramic crown to restore a damaged tooth. In this video, the final colourings and glaze are applied to the restoration to give it a life-like appearance.

Restoring a tooth (CAD-CAM Ceramic) - Part 4

This video shows the first stage of the production of a ceramic crown to restore a damaged tooth. In this video, the model of the tooth is scanned into the Computer-Aided-Design system (Cerec InLab) and prepared for milling.

This video shows the first stage of the production of a cast gold crown for a damaged tooth. The crown is made on the model using wax, which will be replaced by molten gold in the lost wax casting process. The technique of making the wax template and adjusting it to fit the model accurately is shown.

Before the construction of a dental prosthesis (in this case a crown for a damaged tooth) can begin, a model is made from an artificial stone using an impression of the mouth taken in silicone. This video shows the process of cutting the model into pieces to allow for easy access to important areas. The section of the model where the prosthesis will be made is further prepared with a hardening solution, and a paint-on spacing lacquer.

Constructing a plaster model of the dentition - Part 3

Before the construction of a dental prosthesis (in this case a crown for a damaged tooth) can begin, a model is made from an artificial stone using an impression of the mouth taken in silicone. This video shows the initial stages of making a model suitable for making a customised dental prosthesis.

This video shows the second stage of the production of a cast gold crown for a damaged tooth. The wax template of the tooth is sprued using wax wire, then invested in a refractory investment material. The video shows the mould being heated to both expand it and prevent against thermal shock. A centrifugal casting process is shown, using an electrical furnace for melting the gold.

Restoring a tooth (Gold Crown) - Part 2

This video shows the final stage of the production of a cast gold crown for a damaged tooth. The gold casting is cooled and removed from the mould. Sand blasting, an acid bath and then a series of abrasive burs are used to trim and finish the casting before a final polish is applied.

Dental Technology - Making Fixed Restorations

Before the construction of a dental prosthesis (in this case a crown for a damaged tooth) can begin, a model of the dentition must be made. This video shows the process of using silicone materials (supported in a tray) to record the shape of the teeth. For clarity the process is shown on the workbench.
