Las fracturas en mandíbula atrófica han sido tratadas desde con fijación intermaxilar hasta con osteosíntesis. Pueden requerir injertos óseos. La clasificación de Luhr es una guía para orientar el tratamiento.  Objetivo. Mostrar el tratamiento de fracturas en mandíbula atrófica con placas y tornillos y las posibles indicaciones de uso de injerto óseo en este tipo de fracturas.  Método. Se presenta una serie de 17 pacientes con mandíbula atrófica fracturada tratada con placas y tornillos, algunas con sistemas no bloqueados y otros bloqueados. En las de clase II and III se aplicó injerto óseo esponjoso para mejorar la capacidad osteogénica. El injerto se tomó del tercio proximal de la tibia, previa evaluación radiológica.  Resultados. La evolución en general fue satisfactoria. Se inició la vía oral con papillas y los pacientes deambularon a las 24 h de posoperatorio. Se observó consolidación en 17 pacientes. Hubo una defunción por enfermedad vascular cerebral antes de 6 meses. Una paciente tuvo retardo de consolidación diagnosticado al tercer mes, pero no aceptó tratamiento secundario.  Conclusiones. El tratamiento de las fracturas mandibulares atróficas con placa y tornillos bajo concepto de carga absorbida es un procedimiento confiable. La clasificación de Luhr es útil para orientar la utilización de injerto óseo, buscando mejorar la capacidad osteogénica en la fractura. Este tratamiento permite un pronto reinicio de la vía oral, así como la movilización de los pacientes.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  Background. Fractures of the atrophic mandible have been historically treated in various ways, from intermaxillary fixation to internal fixation, some cases require bone grafts. Besides, the Luhr classification serves as a guide to select the type of treatment.  Objective. To show the treatment of fractures in atrophic mandible with plates and screws, and the potential indications of bone graft in this type of fractures.  Method. We presented a serie of 17 patients with atrophic mandible treated with plates and screws, some of them no blocked system and other with locked screws. For patients in luhr classes II and III cancellous bone grafts were used, looking for best osteogenic response, harvesting for the proximal third of the tibia.  Results. Postoperative progress was generally uneventful. Oral intake with purees was resumed 24 hours after surgery, as well as ambulation. Fracture healing at 6 months was seen in 17 patients. One patient died before the 6-month time point as the result of a stroke. Delayed union was diagnosed 3 months after surgery in another patient, who refused secondary treatment.  Conclusions. Treatment of fractures in atrophic mandibles with plates and screws is a reliable procedure. Luhr classification provide useful guidance regarding the use of bone grafts for best osteogenic response in the fracture. This treatment allows a quick restart of the feeding by mouth and movilization of the patients.]]></p></abstract>
