Purpose and goal

The aim was to develop an industrial process for producing ceramic dental crowns. The material on which the project is based has been in clinical use for many years. Ceramic crowns that are made in the material in its present form, however, cannot be bonded to the teeth to be treated, hence dentists need to grind away a substantial amount of sound tooth structure in order to gain retention for the crowns, which is not needed with the new technology. The aim of the project was to verify the clinical versatility of the product as a basis for a forthcoming clinical trial. This aim is fulfilled.

Expected results and effects

The industrial production process is verified through the partner Bra Tänder AB and the quality level of the process ensured for use on realistic clinical tooth preparations. The result is analyzed and the method ready to be used clinically in a pilot trial. The purpose of the project was to verify the clinical utility of the product as a basis for the forthcoming clinical trial. The outcome is completely in line with the expected effects.

Planned approach and implementation

The production has been made in a buid-up production line that has been set up for the project (Bra Tänder AB). Dental crowns have been produced based on realistic patient cases to verify that the method is suitable for all types of geometric variations that occur clinically. After production, the crowns have been examined and analyzed for quality and clinical utility. Analyzes of bond strength, surface topography and the chemical composition in the material surface have been tested and analyzed with expected outcome. Thus, the project is ready for the pilot trial.
