During the past decade, the use of osseointegrated implants as a foundation for prosthetic replacement of missing teeth has become highly predictable and successful. SPT(Supportive Periodontal Therapy) identified as regular visits to the therapist for periodontal control and maintenance in a well-organized scheme, the number of appointments per year following a pre-designed subject-tooth/implant-site risk assessment method. Peri-implant disease was a frequent finding in subjects having natural healthy dentition and in subjects without periodontitis. Supportive periodontal program were found to be strongly related to implant survival. This study demonstrates that regular maintenance reduces the risk for peri-implant inflammation significantly as compared with irregular maintenance. This underlines the value of the SPT in enhancing the long-term outcomes of implant therapy, particularly in subjects affected by periodontitis, in order to control reinfection and limit biological complications. It is highly recommended to maintain implant patients under a strict supportive periodontal treatment protocol that might contribute to implant survival, and regular maintenance reduces the risk for periimplant inflammation significantly as compared with irregular maintenance. Ideally, patients may be informed on the beneficial effect of a regular patient-related post-therapy care before implant insertion.
Because the implant is regarded as a common treatment. It is clinically important that systemic and local risk factor of threatening peri implant mucosa should be considered during the process. The most risk factors are detected in clinical diagnosis,but it might be difficult and not clear to recognize systemic or combined factors. This article reviews risk factors of peri-implantitis. Local factors are biomechanics, periodontal soft tissue characteristics,infected site and oral hygiene. Systemic factors are alcohol, smoking and genetic traits
The aim of this study was to achieve the healing of peri-implantitis defects and the hard tissue regeneration using the augmentation of a xenograft on defect site. Two patients were treated with the surgical approach. With a full muco-periosteal flap elevation, the implant surfaces were exposed and taken the debridement of granulation tissue around the abutment. Each surface of the abutments was prepared with the air-abrasive device (PerioFlow ) for decontamination. Bovine-derived bone mineral (Bio-Oss collagen ) was then used to fill the defects, and no membrane was placed on the grafting site. Radiographs and clinical photo was taken to compare from baseline status. Within the limits of the present case, this case shows the significance of the surgical treatment of peri-implantitis. And this also verifies the stability of bovine-derived bone mineral and effectiveness of Air-abrasive device (PerioFlow ).
