METHOD FOR DIMENSIONAL ADJUSTMENT FOR DENTAL SCAN, DIGITIZED MODEL OR RESTORATION

摘要

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.

主权项

1. A method for creating a substantially accurate dental restoration, the method comprising:
a) scanning a negative dental impression of a patient's teeth or a positive dental stone model of the patient's teeth using a three dimensional scanner to create a scan of the patient's teeth, the negative dental impression being shrunk with respect to the patient's teeth, or the positive dental stone model being shrunk or enlarged with respect to the patients teeth; b) applying a compensation rate, to compensate for the shrunk or enlarged scan of the patients teeth, to:
i) the scan of the patient's teeth using the scanner to create a true dimension working file, and saving the true dimension working file prior to designing and fabricating the restoration; orii) the scan of the patient's teeth using a computer system to create a true dimension working file prior to designing and fabricating the restoration; oriii) a shrunk or enlarged restoration file of the restoration using the restoration fabricator prior to fabricating the restoration; c) designing a restoration based on the scan of the patient's teeth and creating a restoration file; and d) fabricating the restoration using a restoration fabricator.
