Abstract

Peri-implantitis is one of the most prevalent complications of osseointegrated implants which can cause explantation. The aim of this report is to introduce cases of reconstruction of alveolar ridge and replacement of implant using Guided Bone Regeneration (GBR) on the site of implant removal due to peri-implantitis. In case 1, Ridge Augmentation using GBR with titanium-reinforced Gore-Tex augmentation membranes (TR-GTAM) and deproteinized bovine bone mineral (DBBM, Bio-Oss) combined with auto bone was performed at 5 months after explanatation of #14i, 15i, 16i. 11 months later, #14i, 16i implants were replaced on the previous failure site. Second surgery was performed 4 months later, accompanied by free gingival graft. In case 2, severe vertical and horizontal bone loss was observed 3 months after explantation of #16i, 17i, ridge augmentation using GBR with TR-GTAM, Bio-Oss and recombinant human Bone Morphogenetic Protein-2 (rhBMP-2, Novosis) was performed. 7 months later, #16i, 17i implants were installed with sinus lifting and apically positioned flap. In case 3, severe vertical bone loss was observed on #13i which has been installed with vertical augmentation simultaneously. The inflamed implant was removed, followed by ridge preservation using DBBM with collagen (Bio-Oss Collagen) and collagen membrane (OSSIX PLUS). At 1 year after explantation, ridge augmentation using TRGTAM
and Bio-Oss was performed. 3 months later, membrane was removed and implant was placed with connective tissue graft
using modified roll technique. Though membrane exposure was observed on case 2 and 3, all the surgical sites showed complete healing in the end, with good stability of all implants. Implant failure could be overcome through implant removal followed by reconstruction of the defects using GBR technique and re-installation of implants.
