The Computer Based Diagnostic Setup

Every orthodontic treatment plan is based on comprehensive explicit knowledge (evidence-based, state-of-the-art) and implicit knowledge (experience, intuition). Its formulation also requires the ability of abstraction, since most of its contents is created only in the doctor’s head. Because it is very time consuming to manufacture, an actual diagnostic setup model is only created in very complex cases (i.e. EX/Non-EX). However, in clinical practice it would always be helpful to have a quick visualization available – be it for evaluation of required space, for optimized bracket placement, bending wires or for consultation with the patient. In literature one cannot find a generally accepted "cooking recipe" for a diagnostic setup but a multitude of theories, opinions and guidelines.
This presentation shows the most important concepts for an "ideal" dentition, helpful tools for the manual creation of a setup and software for virtual 3-D treatment planning. We will show how everyone can create a virtual treatment objective by using the orthodontic analysis software OnyxCeph³ as an example. This software offers a semi-automatic setup creation process based on scientific concepts. These and the used visualization tools are demonstrated and the prerequisites for a virtual workflow are shown.
