[Predictability using the "Dentofacial Planner Version 4.22 A" of soft tissue changes following adult orthodontic treatment].
For the prediction of profile changes following orthodontic treatment the computer program "Dentofacial Planner" (DFP) which bases on cephalometric measurements is available. The object of this study is to analyse the precision of the DFP version 4.22 A (release Feb. 89). The material of the study consists of the lateral cephalograms of 33 patients treated for maxillary incisor protrusion. In order to evaluate the ensuing profile changes certain cephalometric parameters are measured pre- and post-therapeutically. They are compared to the values predicted by the DFP. Statistical analysis yields the following results: 1. Clinically acceptable precision was found for seven of the 20 cephalometric parameters. 2. In two of the six parameters stated to be stationary by the DFP notable changes were found in reality. 3. The most accurate prognosis was made for the upper lip profile; the least precision was found for the lower lip. According to the manufacturer the results of this study will be included in alternations of the DFP program so as to achieve improvements in the criticized areas.
