Workflow for Maxilla/Mandible Individual [Mai®] Implant by Integra Implants-How Individual Implants Are Manufactured

Rafał Zieliński et al. Biomedicines. .

Abstract

The newest technology allows the medical industry to manufacture innovative products such as milled titanium prosthodontic parts in an implant for a screw-retained suprastructure. In the literature, there are some articles on the clinical usage of subperiosteal implants, but none of these publications, either in PubMed or Google Scholar, thoroughly describe the workflow for the design and manufacture of individual implants for maxillofacial surgery with milled threads for a screw-retained prosthodontic bridge. The aim of the article is to present a step-by-step method of producing personalized implants, from the first steps of production to the implantation of the final product. The article includes information on patient qualification for surgery, computational preparation and skull printing, planning of Mai Implants®, meshing, 3D printing and milling, cleaning, rinsing, anodizing, and laser marking, as well as the cleaning and sterilization process in a hospital or dental clinic. A detailed description of implant production allows for the analysis of each step and the development of technology. The production of implants is an expensive procedure, but considering all the advantages of the Mai Implants® treatment and the disadvantages of alternatives, the product is worth the price.

Keywords: Mai Implants®; individual implant; subperiosteal implant for maxillofacial; subperiosteal implants; technology process of manufacturing individual implants.
