Prediction of dentofacial changes induced by an articulator intended for orthognathic surgery

Abstract

We attempted to verify the reproducibility of treatment using surgical plates and articulators made especially for surgical‐orthodontic treatment, by making preoperative predictions and conducting post‐operative comparative reviews. We conducted a comparative analysis of preoperative cephalometric values, metrics obtained via “paper surgery", and post‐operative cephalometric values. Furthermore, we examined the orthognathic surgery using pre‐and post‐operative data. The post‐operative metrics were similar to the preoperative predictive values. The tendency to mandibular prognathism was improved. We concluded that surgical plates prepared using this articulator are effective and that this method is very useful for making postoperative predictions. (J Osaka Dent Univ 2019; 53: 161‐169)
