Abstract A concave profile with class III malocclusion is most often due to a combination of maxillary hypoplasia and mandibular hyperplasia. Surgical correction entails normalization of jaw positions and is more challenging in the setting of concurrent asymmetry and open bite. Treatment should optimize both facial harmony and occlusion. Orthognathic surgery for class III deformities occurs at skeletal maturity and should address all aspects of the condition while preventing unnecessary emotional stress from delayed treatment. In this article, the authors describe the 3-jaw orthognathic surgery technique to address maxillary hypoplasia, mandibular prognathism, open bite and mandibular asymmetry in a single procedure. The process of preoperative 3-dimensional virtual surgical planning, detailed surgical technique, fat grafting, and a comparison of pre and postoperative 3D aesthetic outcome is presented. Additionally, a retrospective review of postoperative outcomes of 54 patients who received 3-jaw orthognathic surgery is presented as well.

Maxillary Deficiency

Class III skeletal malocclusion may present several etiologies, among which maxillary deficiency is the most frequent. Bone discrepancy may have an unfavorable impact on esthetics, which is frequently aggravated by the presence of accentuated facial asymmetries. This type of malocclusion is usually treated with association of Orthodontics and orthognathic surgery for correction of occlusion and facial esthetics. This report presents the treatment of a patient aged 15 years and 1 month with Class III skeletal malocclusion, having narrow maxilla, posterior open bite on the left side, anterior crossbite and unilateral posterior crossbite, accentuated negative dentoalveolar discrepancy in the maxillary arch, and maxillary and mandibular midline shift. Clinical examination also revealed maxillary hypoplasia, increased lower one third of the face, concave bone and facial profiles and facial asymmetry with mandibular deviation to the left side. The treatment was performed in three phases: presurgical orthodontic preparation, orthognathic surgery and orthodontic finishing. In reviewing the patient's final records, the major goals set at the beginning of treatment were successfully achieved, providing the patient with adequate masticatory function and pleasant facial esthetics.

Record Data

Introduction: Angle classification is a classification commonly used for malocclusion in the field of orthodontics. Mandibular prognation is one of the skeletal features of Class III dentoskeletal classification or defined as mesiocclusion. The prevalence of class III dentoskeletal occurrence in Asian populations is much higher than Caucasian racial populations. Aim of research is to obtain data of Orthognathic surgery case overview in patients with class III dentoskeletal angle classification Methods: Type of research is using a retrospective descriptive method by taking secondary data from medical record cards of orthognathic surgery cases. The population in this study were all medical record data of patients undergoing orthognathic surgical treatment in the Oral and Maxillofacial Surgery Department of RSUP Dr. Hasan Sadikin 2006-2011 period. The sample in this study is medical record data of patients with Class III dentoskeletal classification performed orthognathic surgery in the period 2006-2011. then classified by year of surgery, sex, age, Angle classification, state of anterior open bite, location of surgery, and technique used in surgery. Result: 2% of orthognathic surgical patients have a Class III Angle relationship and only 8% of orthognathic surgical patients have a Class II Angle relation. Based on the anterior tooth overbite relation in patients with an Angle class III relationship, there are 16 patients who have an open bite relation on the anterior teeth. Only 8 patients from Angle III class relationships were treated with orthognathy without an anterior open bite relation.Conclusion: In the period 2006-2011, the Department of Oral and Maxillofacial Surgery Dr. Hasan Sadikin handled 26 orthognathic surgical patients, The most orthognathic surgical patients were in the age group of 21-25 years and the difference in the number of male and female patients was only small, Cases of orthognathic surgery in patients with class dentoskeletal Angle classification III is the most handled case by the Department of Oral and Maxillofacial Surgery Dr. Hasan Sadikin Bandung in the period 2006-2011 reached 92.31% of all orthognathic surgery cases or 24 cases. (4) Most orthognathic surgical patients with Class III dentoskeletal classification have an anterior open bite relation. The most commonly performed surgical techniques for patients with Class III dentoskeletal classification are bimaxillary surgical techniques with a combination of Le Fort 1 osteotomy techniques on the maxilla and sagittal split osteotomy and genioplasty of the mandible.

ZusammenfassungDer vorliegende Fallbericht zeigt die Therapie und das Behandlungsergebnis bei einer erwachsenen Patientin mit skelettaler Klasse-III-Dysgnathie. Die 29 Jahre alte Patientin wies eine skelettale Klasse III mit hypoplastischer Maxilla und prognather Mandibula, ein vertikales maxilläres Defizit und einen offenen Biss auf. Aufgrund vorhergehender Behandlungen mit unbefriedigenden Ergebnissen, der skelettalen Diskrepanz und hoher ästhetischer und kaufunktioneller Ansprüche der Patientin wurde eine interdisziplinäre Behandlung durchgeführt, welche Kieferorthopädie, orthognathe Chirurgie und restaurative Arbeiten einschloss.This article shows therapy and treatment result of an adult patient with skeletal Class III malocclusion. The patient of 29 years of age showed a skeletal class III malocclusion due to a hypoplastic maxilla and a prognathic mandible, a vertical maxillary deficit and an open bite. As there had been other treatments before with unsatisfying results and due to the skeletal discrepancy and the high esthetic and functional expectations of the patient, an interdisciplinary treatment involving orthodontics, orthognathic surgery and a restorative rehabilitation was chosen.
