Abstract

The disadvantages of the traditional approach for fabricating dental implant prostheses have been addressed via oral scanning and the use of computer-aided design/computer-aided manufacturing systems. The use of an intraoral scanner can eliminate the need for impression materials and impression trays, which are inconvenient for patients, particularly those with limited mouth opening or an overly sensitive gag reflex. Moreover, it can reduce the additional costs of fabricating, storing, and handling the patients’ models. This case report describes the fabrication of a posterior implant prosthesis using double scanning technique, which produced satisfactory results both esthetically and functionally. The double scanning technique produces a more accurate image of the target region by overlapping data from both intraoral and extraoral scans. Therefore, it can address the disadvantages of both traditional and digital impressions, reduce patient discomfort, and decrease the incidence of remakes, which can arise due to potential errors during the fabrication process.
