Resumo
Introdução: Enxertos ósseos retirados da sínfise ou do ramo mandibular podem ser empregados para reconstrução de defeitos localizados dos maxilares, para permitir a instalação adequada de implantes dentários. Objetivo: Este estudo tem por objetivo avaliar a ocorrência de complicações associadas com as áreas doadoras e receptoras de enxerto ósseo mandibular, e a sobrevivência de implantes dentários instalados nesses sítios reconstruídos. Material e método: Avaliaram-se 730 prontuários de pacientes submetidos a tratamento com implantes dentários. Desse universo, 72 pacientes, de ambos os gêneros, foram submetidos à reconstrução óssea com enxerto retirado da sínfise ou do ramo mandibular. Resultado: Foram observadas 13 complicações e não houve diferença estatística significante quanto à ocorrência de complicações das áreas doadoras e receptoras, e da sobrevivência de implantes dentários instalados nos sítios reconstruídos com enxerto ósseo mandibular. Conclusão: Os enxertos ósseos mandibulares permitem a reconstrução de defeitos localizados dos maxilares e não são fatores de risco para a falha de implantes dentários.

Abstract
Introduction: Grafts bone removed of the symphysis or mandibular ramus can be used for reconstruction located defect jaws to allow adequate installation of dental implants. Objective: This study aims evaluate the occurrence of complications associated with donor and receptor sites of mandibular bone graft and survival of dental implants these reconstructed sites. Material and method: Evaluated seven hundred thirty records of patients submitted treatment with dental implants. This universe, seventy-two patients of both genders, was submitted bone reconstruction with graft removed from the symphysis or the mandibular ramus. Result: Thirteen complications were observed and there was no statistically significant difference in the occurrence of complications of donor and recipient areas and survival of dental implants installed in sites reconstruction with mandibular bone graft. Conclusion: The mandibular bone grafts allow the reconstruction of defects located in jaws and don’t risk factors for failure of dental implants.
