Abstract
A customized dental abutment is provided which replicates a tooth being replaced. The dimensions of the abutment are determined by a computer algorithm that modifies standard tooth type models according to a series of measurements taken of the site of desired tooth replacement. Methods of the invention relate to taking a series of measurements of the site of desired tooth replacement, determining the type of tooth being replaced, and preparing or selecting a customized dental abutment based on the measurements and determination. The preparation or selection is made by modifying standard measurements for the type of tooth being replaced in conformity with the measurements taken of the site of desired tooth replacement.
