Summary
This study presents a streamlined technique for creating implant-supported prostheses using intraoral scanning and CAD-CAM technology. This digital workflow enhances accuracy and efficiency in fabricating dental restorations.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
- Digital Dentistry
Background:
- Traditional fabrication of complete-arch implant-supported fixed prostheses involves multiple steps prone to errors.
- Accurate implant positioning and digital workflow integration are crucial for successful prosthetic outcomes.
Purpose of the Study:
- To describe a novel technique for fabricating complete-arch implant-supported fixed prostheses.
- To integrate intraoral scanning and CAD-CAM technology for enhanced precision and efficiency.
Main Methods:
- A specialized device was developed for precise capture of multiple implant positions and digital surgical guides.
- Metal substructures were designed and milled directly from cobalt-chromium using CAD-CAM.
- Gingiva and artificial tooth colors were selected via intraoral scanner software; prosthesis bases were conventionally processed.
Main Results:
- The described technique simplifies the fabrication process for implant-supported prostheses.
- Direct milling of cobalt-chromium substructures ensures high accuracy and fit.
- Elimination of conventional casting and occlusal registration steps reduces potential errors.
Conclusions:
- Intraoral scanning and CAD-CAM technology offer a reliable and efficient method for fabricating complete-arch implant-supported fixed prostheses.
- This digital approach improves accuracy and minimizes errors compared to traditional techniques.
- The technique facilitates predictable and esthetic outcomes in implant dentistry.
