Peri-Implantitis: A Review of the Disease and Report of a Case Treated with Allograft to Achieve Bone Regeneration.
Dental implants offer excellent tooth replacement options however; peri-implantitis
can limit their clinical success by causing failure.
Peri-implantitis is an inflammatory process around dental implants resulting in bone loss in association with bleeding and suppuration.
Dental plaque is at the center of its etiology, and in addition, systemic diseases, smoking, and
parafunctional habits are also implicated.
The pathogenic species associated with peri-implantitis include, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Tannerella forsythia.
The goal in the management of peri-implantitis is the complete resolution of
peri-implant infection with function.
Therapies using various biomaterials to deliver antibiotics have been used in the treatment of peri-implantitis e.g. fibers, gels, and beads.
The use of guided tissue regeneration barrier membranes loaded with antimicrobials has shown success in re-osseointegrating the infected implants in animal models. Several uncertainties still remain regarding the management of peri-implantitis.
The purpose of this article is to present a background of peri-implantitis along with a case of peri-implantitis successfully treated for bone regeneration.
Tooth loss occurs for a variety of reasons and results in resorption of the alveolar
ridge if left unreplaced.
Achievement of successful periodontal regeneration provides a great
challenge to the dental surgeons.
Dental implants are a successful in replacing teeth, with implant survival rates reported to be greater than 89% at 10-15 years follow up.
Around two million implants are placed each year and the number of implants placed per year is expected to increase both due to the success of implant therapies and the aging world population.
While success rates of dental implants are initially quite high, 6-12% of dental implants fail and are
lost or must be removed.
