Evaluation of implant survival in atrophic jaws reconstructed with calvarial bone graft

The aim of this study was to analyze the survival rates of installed implants in atrophic maxillae reconstructed with calvarial bone graft. Was realized a retrospective study that evaluated the survival rate of implants, through the collection of data from medical records, including variables such as age and sex, type of reconstruction performed, number and platform of the installed implants, type of implant loss, the region of loss, as well as the time of clinical follow-up, through descriptive and exploratory data analysis. The sequence of removal, han- dling and stabilization of the calvarial bone graft, in addition to the installation of implants and prosthetic preparation followed routine standards and parameters established in the literature. The reconstruction of atrophic maxillae with autogenous calvarial bone graft provided high survival rates for dental implants, proving to be predictable. Of the 15 patients analyzed, 13 (86.7%) had survival of all implants, with only two cases of early loss of dental implants, showing that for a total of 95 dental implants installed in the reconstructed jaws, the survival rate was 97.9%. The calvarial bone as a donor area for reconstructions, prior to the installation of implants, therefore, represents a great alternative, allowing the correction of bone deficiencies and providing stability and maintenance of bone volume, with satisfactory results regarding implant survival and low failure rates.
