Nowadays, the use of implant-retained prostheses has been increasing progressively since the advent of the osseointegration. The basic indication was in total edentulous patients and it was also enlarged for partially edentulous patients. Alternatives of retention could be from screw-retained implant prostheses, cement-retained implant prostheses or conventional preparations. Cement-retained implant prostheses are used frequently when the implant inclination don't allow the use of screw-retained prostheses because the screw emerge in vestibular surface or the interdental space resulting in an unaesthetic appearance and when the screw emerge on the top of the posterior cuspid teeth, diminishing the resistance. The confection of the copings on the abutments, turn the treatment faster and secure. Although, some complications can appear in the placement, because the abutment can take different positions in relation to the implant modifying the set of the prosthesis, mainly in clinical situations with more than two implants support. Thus, the aim of this study was demonstrated the use of guide to positioning of cement-retained implant prostheses, by means of a clinical case.
