A method for creating a substantially accurate dental restoration from scanning a negative dental impression of a patient's teeth or a positive dental stone model of the patient's teeth includes applying a compensation rate to compensate for the shrunk or enlarged scan of the patients teeth, to the scan of the patient's teeth using the scanner to create a true dimension working file； the scan of the patient's teeth using a computer system to create a true dimension working file； or a shrunk restoration file of the restoration using a restoration fabricator. A restoration can be designed based on the scan of the patient's teeth and creating a restoration file. The restoration can be fabricated using a restoration fabricator.
