RESUMO
This article describes the removal of a malpositioned dental implant, using an implant retriever, followed by guided tissue regeneration with the use of an xenogeneic graft and a dense polytetrafluorethylene membrane that remained partially exposed for 28 days, and the post-surgical prosthetic and orthodontic treatment until conclusion of the oral rehabilitation procedure. The patient, 50 years of age, presented to a private clinic for evaluation of an implant supported fixed crown, with unsatisfactory esthetic appearance and function. The treatment plan involved the removal of this implant, guided bone regeneration, and placement of a new implant in a better 3D position. Subsequently, the patient received a provisional dental prosthesis, orthodontic treatment in order to realign the gingival margins, and additional rehabilitation with the application of some ceramic veneers to enhance the patient's esthetic appearance, improve function, and show the 1-year follow-up of the case. The treatment plan was shown to be appropriate for this case, in which soft and hard tissue were adequately regenerated, and resulted in good oral rehabilitation with tissue stability around the teeth and implant.

O uso de membranas em casos de regeneração óssea guiada tornou-se comum e representa um recurso para ganho de tecido ósseo. As membranas de politetrafluoretileno denso (d-PTFE) são uma opção quando há necessidade de mantê-las expostas ao meio bucal. Neste estudo, relata-se a utilização de uma membrana d-PTFE para regeneração óssea em alvéolo pós-extração em região estética.
The use of membranes in cases of guided bone regeneration has become common and represents a resource for bone tissue gain. Dense polytetrafl uoroethylene (d-PTFE) membranes are an option when there is a need to keep them exposed in the oral cavity. In this study, we report the use of a d-PTFE membrane for bone regeneration in the post-extraction socket in the esthetic zone.
