Substituição de implante associada a reconstrução tecidual: relato de caso

Abstract

The replacement of a dental implant is indicated in cases of failure osseointegration, aesthetic or functional dissatisfaction, peri-implant infections, and fractures. This replacement is often associated with the need for bone and connective tissue grafting, na association that plays a key role in ensuring aesthetic, functionality, and natural appearence. The aim of this study is to

report a clinical case of replacement of an external hexagon implant with incorrect three- dimensional positioning in the anterior maxillary region at thoot 12, accompanied by the

absence of vestibular bone tab, describing the therapeutic approach adopted, which includes removal of the implant using the reverse torque technique, with the aid of a ratchet and retrivier, followed by replacement with a Morse taper model, as well as particulate xenogeneic bone graft and autogenous connective tissue. The 50-year-old patient presented with an unsatisfactory aesthetic and functional condition. Imaging revealed incorrect three-dimensional positioning associated with bone plate destruction and tissue loss, which were decisive factors in the decision-making process.
