title: Finding Z: a mathematical method for predicting tissue position after implant abutment-restoration placement.
abstract: A visible abutment-restorative interface is a problematic consequence, especially in the esthetic zone. This article presents formulas to predict the vertical tissue position around the abutment-restoration, which can be used both as a guide to the clinical situation and as an aid to computer-aided design and computer-aided manufacturing design.
