Guided Bone Ridge Augmentation: A Clinicohistologic and Radiographic 2 Years Follow-up

Abstract

Background: Augmentation of the bone is done to create the sufficient bone volume for ideal implant placement. This case report presents the effective augmentation of the socket using corticocancellous graft and AlloDerm. Methods: Failing 47 was extracted. Socket had a severe buccal dehiscence extending and a thin keratinized mucosa around. After through debridement, socket walls were decorticated and corticocancellous graft and allograft GBR was tacked over the socket. Mucoperiosteal flap was sutured with 5-0 nylon sutures (Ethicon) Bone core biopsy was done for histologic assessment and site was restored with screw-retained implant prosthesis. Results: Histologic assessment revealed ingrowth of new bone around the bone graft. Stable soft and hard tissue results have been seen with 2 years follow-up of the case. Conclusion: Results indicated that ridge preservation using corticocancellous graft and AlloDerm prevented the ridge resorption and helped in enhancement of bone fill and soft tissue volume.
