ABSTRACT

Autogenous bone grafts are used in the management of atrophic ridges; the aim of this investigation was to determine the complications associated with the reconstruction of the alveolar defect with an autogenous bone grafts. Were included male and female patients with alveolar atrophy in areas with no teeth and no more than three contiguous teeth, using an autogenous bone in block or in particles, being used for the lift of the maxillary sinus or for the horizontal increase of ridge. Was observed the presence of early complications such as increased facial volume, infection or neurosensory alterations and late complications such as increased reabsorption of the graft or late neurosensory alterations. The value of p < 0.05 was used for statistically analyzed to obtain statistical significance. 83 patients with an average age of 54.8 years and 143 surgeries were included. Grafts were exclusively in block for 52.4%, exclusively in particle for 42.6% and a mixture of both in 4.8%; the most commonly used sites were the mandibular ramus (80.3%) and the mandibular symphysis (15.8%). Complications were observed in 6.3% of the sites included to bone augmentation (nine sites) associated mainly with the lack integration of the grafts and wound dehiscence. Autogenous bone grafts have low morbidity; The donor site of choice is the mandibular ramus and can be used as a block or as a particle with low complications.
