Multidisciplinary management of implant failure: A case report

This case report presents the interest of multidisciplinary management of extreme peri-implantitis requiring removal of implant emphasizing the different surgical and showing that the ovate pontic of conventional bridge is an optimal alternative for rehabilitation of the premolar sector, despite the fact that its main diffusion has been in the anterior sector due to the high demand aesthetic.

Peri-implantitis leads to gradual peri-implant bone loss. Severe and extreme cases lead to complete implant failure and imply lost implants have to be removed. Residual ridge deformity management after implant removal is one of the factors contributing to improved aesthetic and functional results. Various grafting procedures have been developed to achieve this goal. This report describes a case of implant removal from the upper right first premolar due to advanced peri-implantitis in a 51-year-old female patient. Guided bone regeneration with a alloplastic bone graft and resorbable collagen membrane combined with roll pedicle connective tissue graftt was used for both socket and soft-tissue augmentation. This was combined with ovate design conventional provisional bridge. After a 6-month of healing phase, a perfect adaptation of the marginal gingiva around the provisional restoration was obtained. Cone beam computed tomography revealed significant bone fill and buccolingual dimensional stability. A conventional all-ceramic bridge with an oval pontic design was chosen as a definitive prosthetic solution to compensate for edentulism and maintain the good aesthetic results. According to the encouraging result obtained in this clinical case, the conventional prosthetic restoration associated with surgical reconstruction of failing tissues can be considered as a successful treatment in the case of advanced peri-implantitis requiring implant removal.
