OBJETIVE: We try to evaluate if there statistical relation betwen bone mrginal resorption and bone quality around Branemark implants afther 3 and 5 years of prosthodontic function.  MATERIALS AND METHODS: We have controIled 139 Branemark implants from fixed bridges treated in the Implantology Service of The Dentistry Faculty of Madrid. Sistematic radiological exams were made in a 3 and 5 year controls.  RESULTS: Values obtained demonstrates there is no relation between bone quality and marginal resorption after 3 years function, but we obtained less resorption after 5 years in those implantsthat presented a better bone quality in the 3 years control. Those fixtures with less marginal resorption in the first period achieve a better bone quality in the second one. FinaIly,minor values in the bone resorption are in direct relation in the 3 and 5 years control.  CONCLUSIONS: In our sample, a statiscal relation between both studied parameters is evident, but it does not permit us to make long term predictions from observed results after three years. Although we can say that good bone quality observed during the first revisions seems to guarantee less reabsorptions in the future, we cannot assure that less quality wiIl result in a failed treatment.
