We are developing the applications of metaverse (embedded with Al) and 4D printers in the dental industry where millions of people may take advantage of these cutting-edge high technologies. Firstly, we will use virtual reality glasses for the evaluation of oral and facial criteria and the simulation of possible treatment alternatives in dentistry. Secondly, with the use of machine learning for optimization, details will be printed by a 4D printer. Finally, the dentist is required to perform the necessary activities with the benefits of the metaverse and 4d printing for correct treatment. With this project, the most optimal scenario can be implemented in the shortest time and with the lowest cost and minimum further problems.
