Abstract
A method for fabrication of a restoration for a patient's dentition by pinhead molding comprising the steps of examining the patient's dentition, restoring gross areas of tooth loss, and restoring proper anatomy and contour of the dentition, forming a first optically correct impression of the dentition and scanning the first impression to provide a first data set, appropriately isolating and preparing the patient's dentition for the dental restoration, forming a second optically correct impression of the dentition and scanning the second impression to form a second data set, comparing the first and second data sets and deriving a third data set based upon the comparison, the third data set being descriptive of a restoration to be prepared, and forming the restoration by pinhead molding of a flowable composite material in accordance with the third data set. An apparatus is also described for fabrication of a restoration for a patient's dentition.
