A Dental Implant Treatment for Harmonized Esthetic and Occlusal Function of the Patient with Severe Periodontal Disease

It is well known fact that osseointegrated dental implants carry out the new situation for resent prosthetic restoration. However, it has had various problems when clinicians treated implant prosthesis during not only chewing movement but also esthetic viewpoint with severely alveolar ridge resorption. Therefore, in the severely atrophic jaw which caused by severe periodontal disease, prosthetic rehabilitation using dental implant has been very difficult. In the cases of thease problems. the reconstruction with bone grafting, distraction osteogenesis, GBR (Guided Bone regeneration) and the substructure (*) may resolve this problems. This is a case of Severely atrophic edentulous maxilla was reconstructed with substructure(*) which was made by tooth crown and gingiva individually. *) substructure new ways of designing suprastructures for fixed implant-supported prosthesis.4) Reconstruction with implementing suprastructure that has separating crown parts from gingival parts.
