“…Se han realizado varios estudios sobre el uso del transporte del segmento óseo para el cierre de hendiduras alveolares (17). Las ventajas de la DO sobre la reconstrucción alveolar tradicional son las siguientes: no hay necesidad de injertos óseos que involucren un sitio donante, tiempo quirúrgico mínimo, no hospitalización y mejora progresiva con excelente adaptación psicológica.…”

Introducción: El tratamiento de la hendidura alveolar, del paciente fisurado, permite un adecuado crecimiento facial. Los injertos óseos han sido el tratamiento ideal. Sin embargo la técnica de distracción osteogénica mediante transporte óseo alveolar intraoral ha demostrado ser muy predecible. Objetivo: Describir los resultados del cierre de la Hendidura alveolar, con la técnica de transporte óseo alveolar intraoral bifocal y trifocal en pacientes labio fisurados. Diseño: Estudio retrospectivo de serie de casos. Materiales y métodos: Fueron tratados 4 pacientes con hendidura alveolar unilateral, manejados con la técnica de transporte óseo alveolar intraoral bifocal y trifocal en el año 2008 al 2009, con un seguimiento hasta el año 2014. Todos los pacientes fueron tratados con un aparato Hyrax® (Dentaurum, Alemania) modificado. Resultados: El promedio de distancia del transporte óseo requerido fue de 9,75mm (rango de 15 mm a 9 mm). Se colocaron 5 implantes dentales rehabilitados con prótesis dental fija. Conclusión: El estudio de los casos clínicos demuestra una predictibilidadelevada así como un rango de éxito alto, en los individuos tratados conesta técnica. Por tal motivo el transporte óseo alveolar intraoral es una alternativa eficaz para el tratamiento de hendiduras alveolares extensas.Introduction: The management of alveolar cleft patients, allows an adequate facial growth in cleft lip and palate patients. Bone grafts have been the gold standard treatment. However, the technique of osteogenic distraction by intraoral alveolar bone transportation has proven to be highly predictable. Objective: To describe the results of alveolar cleft management with the intraoral bifocal and trifocal alveolar bone transportation technique in cleft palate patients. Design of study: Retrospective case series study. Materials and methods: 4 patients with unilateral alveolar cleft were treated with the bifocal and trifocal intraoral alveolar bone transportation technique from 2008 to 2009. The cases were followed up until 2014. All patients were treated with a modified Hyrax® (Dentaurum, Germany) device. Results: The average distance of bone transportation required was 9.75mm (range from 15mm to 9mm). 5 dental implants with fixed dental prosthesis were placed. Conclusion: Clinical cases study demonstrated a high predictability, as well as a high success ratein individuals treated with this technique. Therefore, intraoral alveolar bone transportation is an effective alternative for the management of extensive alveolar clefts.

“…15,16 Several authors achieved the same objectives while treating patients with alveolar and palatal cleft, obtaining good functional results, and also showed that superior aesthetical dental rehabilitation is possible with implants and orthodontic treatment. 10,11,[17][18][19] Immediate application of distractors at the same surgical time of bone tumors excision was previously described as a successfully reconstructive option in the mandible, both in experimental works and also in clinical cases. 20,21 In the maxilla, the three-dimensional complexity of bone framework separating the oral cavity from nasal and sinus cavities, specialization of the attached mucosa, and aesthet-ical importance of the anterior dental arch present several particularities when considering this reconstructive option.…”

“…In the case of bone transport, a third surgical procedure is needed to develop a compress focus when the transport disc meets the contralateral side of the defect or when both transport discs meet together on the middle of the defect, with debridement of interposed soft tissues and bone graft, sometimes called "docking site surgery." 10,11 If the process of reconstruction could be done or at least started at the same surgical time of tumor excision, without compromising the full oncological treatment, this would be one obvious advantage. If the defect created by tumor excision could be left open without soft-tissue coverage, the first operative time could be shortened and the intermediate surgical docking site procedure for debridement of interposed soft tissues and bone grafting would not be required.…”

Maxillary segmental defects are a reconstructive challenge particularly when the anterior arch is involved. Missing bone, mucosa, and teeth should be replaced; fistulae closure should be guaranteed by bone and mucosa continuity; stable functional occlusion should be achieved; and facial aesthetics restored. These defects resulting from tumor excisions, if left untreated, will cause additional problems related to interposed scar and collapse of lip and nose. Immediate reconstruction should avoid these problems and should be considered when safe tumor-free margins are obtained. This study describes the treatment of such a defect resulting from a myxoma excision, with trifocal distraction requiring only one additional surgery. Internal distractors were fixed bilaterally for transport of two segmental discs created by inverted L osteotomies at the same surgical time of tumor excision. A second surgery was performed after central contact between transport discs was achieved, for device removal and creation of a dynamic system to regenerate molding and compression-focus development. This was accomplished by internal fixation of one side and central fixation of a full-open distractor to act as compression device when reversely activated. Central perfect adaptation between transported segments and good-quality attached mucosa lining the alveolar crest were determinant to obtain a stable functional and aesthetic result.

“…Maxillary distraction osteogenesis has shown successful results in the treating the patients suffering from Crouzon syndrome [40,41,42], Sotos Syndrome [43], traumatic or oncologic surgical maxillofacial resections [44,45], and severe maxillary hypoplasia in cleft lip and palate [46,47]. Studies have shown distraction osteogenesis to be a better option than orthognathic surgery for the treatment of patients requiring moderate to large advancements with significant structural deficiencies of the maxilla [48].…”

Distraction osteogenesis has emerged as an effective treatment modality for the correction of bone anomalies and abnormalities which are either pathological or developmental in origin. Earlier it was predominantly used in orthopaedics for the correction of axial skeleton. Its use in the field of dentistry began in the late twentieth century. Successful results from the initial clinical trials prompted more and more researchers to explore this field. Its use in dentistry involves the correction of craniofacial anomalies, alveolar ridge for the prosthetic rehabilitation and recently for the regeneration of lost periodontium.
