Thirty patients (9 men; 21 women) (N=62 distal implants) were followed, with 25 in maxilla and 37 in the mand?ble, at the PUCRS college of dentistry, after 1 and 3 years of prosthesis installation. The prosthetic cantilever measurement was performed during the treatment rehabilitation and the mesio-distal inclination of the most distal implants was obtained with computed tomography (CBCT), intraoral digital radiographs of the distal implants were obtained with customized devices at baseline, 1 and 3 years after prostheses installation. The mean bone loss after 1 year was 0,23?0,36mm after 1 and 3 years was 0,28?0,41mm and after 3 years was 0,35?0,49mm, the mean cantilever extension was 9.91?5.98 and the mean inclination of the implants was 8.68?5.97 in the mesial and 6.46?5.58 in the distal side. There was no statistical correlation between marginal bone loss, cantilever extension and mesiodistal inclination of the most distal implant, after one year of follow-up, where the data were analyzed using Spearman's correlation coefficient (?=5%). It can be concluded that the extension of the distal cantilever and the mesio-distal inclination of the implant in FCDIs not showed relation with marginal bone loss in the most distal implant adjacent to the cantilever. === Este estudo tem como objetivos avaliar a perda ?ssea marginal em implantes distais adjacentes ao cantilever prot?tico em pr?teses totais fixas implantossuportadas (PTFIs) e a poss?vel correla??o da perda ?ssea com extens?o de cantilever prot?tico e inclina??o m?sio-distal do implante distal. Foram acompanhados 30 pacientes (9 homens; 21 mulheres) com 62 implantes distais, sendo 25 na maxila e 37 na mand?bula, colocados na Faculdade de Odontologia da PUCRS, ap?s 1 e 3 anos da sua instala??o da pr?tese. A medi??o do cantilever prot?tico foi realizada durante o tratamento reabilitador e a inclina??o m?sio-distal dos implantes foi obtida com tomografias computadorizadas (CBCT). Radiografias intrabucais digitais dos implantes mais distais foram obtidas com posicionadores customizados ap?s a instala??o das pr?teses (baseline), 1 e 3 anos ap?s o t?rmino do tratamento. A perda ?ssea m?dia ap?s 1 ano foi de 0,23?0,36mm, entre o primeiro e terceiro ano foi 0,28?0,41mm e acumulada durante 3 anos foi 0,35?0,49mm, a extens?o de cantilever m?dia foi 9,91?5,98mm e a inclina??o m?dia dos implantes foi 8,68?5,97 na mesial e 6,46?5,58 na distal. N?o houve correla??o estat?stica entre perda ?ssea marginal, extens?o de cantilever prot?tico e inclina??o m?sio-distal do implante mais distal, durante o per?odo de acompanhamento, onde os dados foram analisados com coeficiente de correla??o de Spearman (? = 5%). Pode-se concluir que a extens?o do cantilever para distal e a inclina??o m?sio-distal dos implantes distais em PTFIs n?o apresentaram rela??o com a perda ?ssea marginal do implante mais distal, adjacente ao cantilever prot?tico.
