Summary
This study presents a digital workflow for creating immediate implant restorations. This method simplifies fabrication, reduces chair time, and improves esthetics in challenging dental implant cases.
Area of Science:
- Dental Implantology
- Prosthodontics
- Digital Dentistry
Background:
- Traditionally, interim crowns for immediate implants use prefabricated hollow crowns and interim abutments.
- Fabrication often involves significant chair time for adaptation and resin relining, potentially compromising esthetics.
Purpose of the Study:
- To describe an alternative digital workflow for fabricating immediate monolithic implant-supported interim restorations.
- To introduce a method utilizing a prefabricated screw-access channel and positioning device.
- To leverage prosthetically driven implant planning with CAD-CAM technology.
Main Methods:
- The workflow employs computer-aided design and computer-aided manufacturing (CAD-CAM) for prosthetically driven implant planning.
- It utilizes a prefabricated screw-access channel and a positioning device for enhanced efficiency.
- This digital approach streamlines the fabrication of monolithic interim restorations.
Main Results:
- The digital workflow significantly reduces chair time compared to traditional methods.
- It eliminates the need for extensive relining resin, improving color stability in esthetic zones.
- The technique facilitates the creation of precise screw-access channels.
Conclusions:
- This digital workflow offers an efficient and esthetic alternative for immediate implant restorations.
- It simplifies the fabrication process, saving valuable chair time for clinicians.
- The method is particularly beneficial for esthetically demanding implant placements.
