QZ is a monthly journal for all dental technicians and professionals interested in dental laboratory technology who appreciate independent and objective information-sharing. QZ articles and reports are focused on information that is of practical relevance to the working dental laboratory technician. This journal provides high-quality professional development resources for dental laboratory technicians, as well as dental industry professionals and prosthetically oriented dentists alike. The increasing proliferation of technology in dental laboratory workflows requires that all members of the dental team have a well-founded and up-to-date knowledge base. QZ provides a quick and current response to these needs. It publishes monthly issues throughout the year, providing more than 120 contemporary articles from professionals who work across the broad field of dental laboratory technology and related fields. Special issues on key topics of current interest are published up to six times per year for a concentrated focus on state-of-the-art knowledge and technology.
