Costs of surgical-orthodontic treatment in community hospital care: an analysis of the different phases of treatment

Abstract

To determine the distribution of costs and various influencing factors in the entire process of surgical-orthodontic treatment in community hospital care, a retrospective study was carried out. The records and radiographs of 99 community hospital patients operated on between 1994 and 2001 were included. Cost analysis data were gathered from 4 phases of treatment: the orthodontics, the surgical outpatient assessments, the surgery/surgeries, and the inpatient period. The results showed that the surgical phases together are responsible for roughly 61% of the costs, 28% of which were attributed to the surgical operation itself. Orthodontics made up approximately 39% of the total costs, with an average of 26 visits. The average total costs of all treatments were US $6,206 +/- 912. Patients that could be operated on with bilateral sagittal split ramus osteotomy of the mandible only had the lowest costs, and those who required bimaxillary osteotomies had the highest costs. Of the several clinical and cephalometric measurements made in this study, only skeletal open bite and orthodontic space closure after tooth extraction were found to affect the costs. It can be concluded that surgical-orthodontic treatment is a rather expensive way to correct dentofacial malocclusions due to the high costs of the surgical phase. Skeletal open bite constituted the most costly entity, while malocclusion resulting from mandibular deformity was the cheapest.
