Technical noteEsthetic Improvement Using Conventional Orthodontic Devices After Segmental Osteotomy in Treatment of Malpositioned Implants
Section snippets
Case 1
A healthy 36-year-old man presented for evaluation of a malpositioned dental implant with mandibular prognathia (Fig 1). Two endosseous implants had been placed in the region of the previously extracted maxillary central incisors and left lateral incisor. If the final prosthetic treatment were performed, the patient would not be able to accept the unsightly appearance of the anterior teeth because of excessive crown height. However, the patient also wanted to correct the mandibular prognathia;
Case 2
A 70-year-old woman was referred for evaluation and treatment of malpositioned endosseous implants (Fig 2). Three implants were placed at the region of the right canine and premolar. The anterior implants at the region of the canine and premolar were inclined with straight abutments buccally, and the patient had a Class II deep-bite tendency. When the final prosthetic treatment was performed, the right canine and premolar were also positioned buccally, and the lower canine and premolar were
Discussion
Correction of dentofacial deformities using surgical-orthodontic approaches has become common. For segmental and dento-osseous osteotomies, many studies have described varying surgical techniques, case reports, and animal studies, confirming the vitality and uneventful healing of the segments involved and the predictable function and esthetic results of surgery.12, 13, 14, 15, 16, 17, 18, 19 Anterior segmental osteotomies have been used to release and reposition impacted ankylosed maxillary

2014, Journal of Cranio-Maxillofacial SurgeryCitation Excerpt :In the previous report, after osteotomy, segments including implants could be moved 3 dimensionally using orthodontic treatment devices. At the same time vertical and horizontal bone regeneration and an aesthetic gingival shape can obtained (Ueki et al., 2011). Consequently, it could be concluded that the orthodontic wire could be useful for the distraction or expansion of the periosteal membrane.
Bone graft sandwich osteotomy to correct a malpositioned dental implant
2013, International Journal of Oral and Maxillofacial SurgeryCitation Excerpt :Stabilization of the mobilized dental osseous segment is another critical factor. There are several methods to ensure satisfactory stabilization, such as: acrylic wafer splint attached to the teeth, archwire fixed with composite resin bonding material, interdental wires, orthodontic appliance, and bone plates.9 The authors used a 1.2-mm bone microplate associated with a sandwich bone graft technique.
