%X introduction: rehabilitation with implants in the upper maxilla often implies a challenge due to the shortage and quality of the remaining bone. different kinds of grafts have been described in an endeavour to solve these problems. aim: the purpose of this study was to assess the osteoconduction potential of an autogenous bone and b-tricalcium phosphate mixture, in the treatment of atrophic upper maxillae. materials and methods: 22 patients were treated using the "sinus lift" technique. all patients had residual bone equal to or greater than 5 mm, the sinus was lifted, bone grafted and implants installed during the same surgical procedure (autologous bone and b- tricalcium phospahate). during the implant exposure after the osseointegration period, samples of regenerated bone were taken using a trephine from 5 patients. paraffin-embedded sections were analysed the structure and tissues percentages. data were estimated statistically. results: clinical results showed integration of the 42 fixtures installed. histological analysis showed good integration of the -tricalcium phosphate in the newly formed bone likewise absence of inflammation. histomorphometric analysis showed a mean bone proportion of 30.7% (range 22.8% - 50.6%). conclusions: results suggest the osteoconductive material b-tricalcium phosphate associated with autologous bone obtained through filtration is an appropriate graft for implant treatment of atrophic maxillae, in combination with the sinus lift procedure.
