Complete restoration of an osseous defect around a TiAl6V4 (IMZ) implant is accomplished by the combined use of an implant placed in the alveolus of a fractured lower bicuspid and the principles of guided tissue regeneration. Gengiflex (Gengiflex--BioFill--Productos Biotecnologicos, Curitiba, PR, Brazil), a new membrane, was used to cover the implant and porous hydroxyapatite was used as grafting material. The filling of the osseous defect that also covered the implant was verified clinically at re-entry 6 months later. Histological analysis of the mineralized tissue collected during exposure of the implant confirmed bone formation.
