Background:

Traditional methods for fabricating dental restorations can be time-consuming and may lack precision.
Digital workflows offer potential improvements in accuracy and efficiency for dental prosthetics.

Purpose of the Study:

To demonstrate the feasibility of using micro-computed tomography (micro-CT) scans of dental impressions for fabricating dental restorations.
To compare the dimensional accuracy of dental models generated from various methods, including the proposed micro-CT approach.

Main Methods:

Dental impressions were digitized using micro-CT scanning.
Digital cast models were generated directly from micro-CT data by segmenting air regions.
The proposed method was validated using a phantom study with a typodont, involving actual measurements and deviation map analysis.
Milled restorations were compared by fitting them to the prepared teeth of the typodont.

Main Results:

Micro-CT scanning of dental impressions allows for accurate digitization.
Digital cast models in STL format can be directly fabricated from micro-CT data.
The proposed method demonstrated efficient fabrication of precise dental restorations.

Conclusions:

Micro-CT scanning of dental impressions is a feasible method for producing accurate digital cast models.
This digital workflow facilitates the efficient and precise fabrication of dental restorations.
The study validates a novel approach for digital dental prosthetics.
