Abstract

For a rehabilitation of mandibular edentulous patient whose posterior alveolar bone is severely resorbed, all-on-X concept is considered for esthetic and functional treatment option. this concept includes four or more implants which is located in an anterior area with immediate dental implant loading of fixed prosthesis after the implant installation. in this case, the temporary denture which is well-fabricated and favorably adapted to patient, is used for making 3-dimensional printed implant surgical guide, provisional fixed prosthesis and a final restoration with a digital technology. this digital workflow is not only for planning the accurate position of several implants, but also for esthetically and functionally well-fabricated final restoration. it is an efficient and well-acceptable result for the patient who is already adapted to the temporary denture. a whole treatment period can be shortened by transferring a maxillomandibular relationship of temporary denture to the final prostheses.
