Abstract

The severe extrusion of the maxillary post.teeth after the early loss of the mandibular post. teeth makes the fabrication of the mandibular prothesis difficult, and without proper planning,the treatment results are often unsatisfactoy. Several treatment modalitys have been introducted to correct the interarch space deficency. :Reduction the occlusal surfaces,Crown lengthening, Endodontics and restorative approach, Extraction, Orthodontic intrusion and segmental osteotomy. Because of many advantages, conservative method is widely used if it has no particular limits of treatment adjustment, but the cases of surgical correction indication are found in clinical experience. In our clinic,we corrected severe extruded maxillary post. teeth by performance of a unilateral posterior osteotomy with superior repositioning of the segment and orthodontic intrusion using Skeletal anchorage system, so here we reported the cases with a study of documents.
