The application of optimization design in stomatology: A literature review

This literature review aims to determine the applications of optimization design in the field of stomatology, to investigate its current usages, methods and benefits. This review was performed following the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. The electronic literature search was performed through MEDLINE, Scopus, Web of Science databases with a 10-year time restriction: January 2012 till April 2022. Abundant studies focused on optimization design of dental implants, maxillofacial surgery fixation plates or implants, prosthodontics were published. Shape optimization has been commonly used in implant prostheses, and various studies have proved it to be an effective method to improve initial stability and reduce maximum stress. Shape optimization and topology optimization have been widely used in maxillofacial surgery to reduce strain, volume, and weight of internal fixation plates or bone block implants. The lack of further in vivo and in invitro tests is one of the main limitations of current published studies.
