[KAP-1] Comprehensive Digital Approach for Cast-Free Maxillary Prosthetic Rehabilitation Using Flapless-Placed Pterygoid Implants
[Abstract]
[Introduction] newline
This case series demonstrate the utilization of flapless-placed pterygoid implants and a full digital workflow for completely edentulous patients requiring implant-supported full-arch fixed dental prostheses (ISFDP). The authors obtained the patients’ consent to participate. Written informed consent was obtained from the patients for the presentation of this case series and accompanying images.
[Case Summary and Treatment Details] newline
Bilateral pterygoid implants were placed using the flapless guided surgery technique. Furthermore, bone reduction was executed on the anterior ridge to ensure stable seating of the surgical guide. Subsequently, standard oral implants were then placed on the anterior ridge. The patients received immediate provisional restoration on the day of implant placement. After 4 months, the scan gauges (NEXUS iOS, Osteon Medical) were screwed onto the intermediate abutments of the implants. Intraoral scans were made, and standard tessellation language (STL) files were obtained. Following the verification of accurate and complete data, a virtual waxup of the final prosthetic plan was created using the CAD software. Without preparing traditional stone casts, the final ISFDPs made of monolithic zirconia were fabricated. Thereafter, the suprastructures were passively luted to the milled titanium bar.
[Progress and Discussion] newline
Digital technologies play a crucial role in the two key stages of edentulous maxillary rehabilitation, namely surgery and the fabrication of the final prostheses1,2). This novel approach simplifies the process, enhances the precision, and reduces the time required for both dentists and dental technicians by leveraging advanced digital tools in both the surgical and prosthetic phases.
