  • Treatment modalities for anterior open bites are aimed at superiorly positioning the maxillary dentition. The purpose of this study is to compare the efficacy and stability of closing anterior open bites with either temporary skeletal anchorage (TSA) or maxillary osteotomy. Cephalograms of TSA and surgery patients were digitized at three different time points. Nine measures were compared to analyze treatment changes and relapse. Unstructured covariance variances were considered. All parameters were estimated by REML method. Success was defined as OB>0mm at the end of the retention period. Positive mean OB was achieved with both treatment modalities. In the retention period, mean positive OB was maintained, however both groups had minor relapse. Overall success rate of TSA was 88% while surgery had 72%. TSA was as effective in obtaining positive OB as maxillary osteotomy in mild to moderate open bite patients and was shown to be stable for over 2 years.
