Natural teeth and prosthesis, a thin line between reality and fantasy. Dental technicians work requires such degree of precision that can make the risk of trespassing from a true to an idealised image of the final product, a daily struggle. Colour combination not only improves aesthetics but also makes the restoration appear natural and attractive. The accuracy of the final product is dependent on how the dental technician gathers all the necessary information required to reproduce a final prosthesis, the most accurate and complete the information is the best levels of accuracy are achieved.
