From: A digital workflow for modeling of custom dental implants
modeling principle: a) original model of the jaw; b) pre-made structures (loops and abutments) added on to virtual model; c) pre-made structures and modelled (bulked) implant merged with original model; d) the 2nd copy of original model (yellow) recalled and matched with model onto which implant was modelled (orange); e) implant – result of Boolean operation, subtraction of yellow model form orange model; f) implant (resultant) model superimposed on the original jaw model.
