11. Excess Cement and Peri-implant Disease By Donald P. Callan, Charles M. Cobb
Among the dental consumer population, dental implants are an increasingly popular option for replacing teeth and restoring function. Since implants became a common modality, assessments of their success have included improved appearance, restored ability to eat, and longevity of placement. By and large, the most appealing appearance drives the choice of dental implants for the patient. However, patients and dentists should be aware of possible complications that could affect the patient’s oral and systemic health, even when excellent esthetic results are achieved. This article demonstrates an excellent esthetic result even with the presence excess subgingival cement following placement of a fixed prosthesis associated with no clinical signs of inflammation but with radiographic signs of peri-implant disease.
21. Iatrogenic Peri-Implantitis: Treatment and One to Two Year Follow up By Pradeep Adatrow, George Hilal, David Cagna, Paul Bland
Peri-implantitis may be associated with a number of variables ranging from patient related to iatrogenic factors. Peri-implant mucosal tissues may be more vulnerable to plaque induced inflammatory changes due to differences in gingival attachment between implants and natural teeth. Local factors that encourage bacterial growth and reduce implant integration should be considered when diagnosing and treating inflammatory lesions identified around restored implants.
31. Bone Regeneration Around a Failing Implant in an Osteopetrotic Patient: A Clinical Case Report By Eric G. Driver, Simon R. MacNeill, Charles M. Cobb
The exact pathogenic mechanism of osteopetrosis is unknown although a deficiency in the osteoclastic enzyme carbonic anhydrase has been observed. Osseous regeneration around failing implants remains a challenging and unpredictable problem. Thus, the pathobiology of osteopetrosis presents an additional complication when treating an osteopetrotic patient presenting with peri-implantitis requiring surgical intervention.
41. Treatment of Peri-implantitis Using Open Flap Debridement and Iodine Solution with Autogenous Bone Graft: A Case Report By Miki Taketomi Saito, Mauro Pedrine Santamaria, Karina Gonzales Silvério, Enilson Antônio Sallum
Peri-implantitis is characterized by bone destruction around dental implants due to the host immune-inflammatory response induced by biofilm accumulation. Several approaches have been proposed to treat peri-implantitis, including mechanic debridement, antimicrobial therapy, and resective or regenerative surgical therapy. The present case report describes a peri-implantitis case treated by a surgical open flap debridement, decontamination of the implant surface with povidone-iodine and fill of the adjacent osseous defect with autogenous bone graft. After 20-month follow-up, the pocket depth reduction and radiographic fill of the defect could be observed. Therefore, it can be concluded that this therapeutic approach could promote clinical and radiographic improvements to the patient. However, more randomized controlled clinical trials are necessary for further understanding about the best approaches for the treatment of peri-implantitis.
