Use of an Autogenous Connective Tissue Graft to Treat Peri-Implantitis With Gingival Recession Affecting an Implant
1Private practice, Manassas, VA.
Introduction:
Bone loss associated with peri-implantitis can result in exposure of the implant surface. A lack of keratinized mucosa has been associated with increased plaque accumulation, attachment loss, and mucosal recession. This case report describes the benefits of connective tissue (CT) grafting in the treatment of peri-implantitis and gingival recession affecting an implant supporting an overdenture. To the best of the author's knowledge, there are few clinical case reports depicting this treatment for implants supporting overdentures.
Case Presentation:
A 75-year-old female was diagnosed with peri-implantitis associated with an implant that supported a mandibular overdenture. The bone loss and gingival recession was on the facial aspect of the implant. The roughened threaded surface of the implant was exposed, and there was an absence of facial keratinized mucosa. Peri-implant therapy included surgical access to debride the area and decontaminate the implant surface using a 3% hydrogen peroxide rinse. This site was then treated with CT grafting using an autogenous CT graft. At the completion of treatment, the implant site was found to be healthy with greatly improved implant coverage and an increased keratinized tissue width.
Conclusion:
The use of an autogenous CT graft can be an important part of treatment of peri-implantitis when there is gingival recession and a lack of keratinized mucosa.
