Restoration of endodontically treated teeth using a CAD-CAM custom post-and-core system: A direct-indirect digital...

Area of Science:

• Restorative Dentistry
• Digital Dentistry
• Biomaterials

Background:

• Endodontically treated teeth require restoration to regain function and aesthetics.
• Traditional post-and-core procedures can be technique-sensitive and time-consuming.
• Digital workflows offer potential for increased precision and efficiency in restorative procedures.

Purpose of the Study:

• To describe a novel digital workflow for fabricating computer-aided design and computer-aided manufacturing (CAD-CAM) custom post-and-core systems.
• To present a streamlined approach for digital post space acquisition using integrated scanning technologies.
• To demonstrate the applicability of a direct-indirect technique for overcoming limitations in digital post space acquisition.

Main Methods:

• Integration of intraoral and extraoral scanning for comprehensive post space digitization.
• Utilizing a direct-indirect technique for digital impression capture.
• Design and fabrication of custom post-and-core restorations using CAD-CAM technology.

Main Results:

• The digital workflow successfully streamlined the process of post space digitization.
• Custom CAD-CAM post-and-core systems were designed and fabricated efficiently.
• The direct-indirect technique proved effective in managing challenges related to digital post space acquisition.

Conclusions:

• The described digital workflow offers an efficient and precise method for restoring endodontically treated teeth with custom CAD-CAM post-and-core systems.
• This technique facilitates overcoming anatomical and technical limitations in digital post space acquisition.
• The integration of scanning and CAD-CAM technology represents a significant advancement in modern restorative dentistry.
