A comprehensive and critical review of dental implant prognosis in periodontally compromised partially edentulous patients

Abstract

No statistically significant differences in both short-term and long-term implant survival exist between patients with a history of chronic periodontitis and periodontally healthy individuals. Patients with a history of chronic periodontitis may exhibit significantly greater long-term probing pocket depth, peri-implant marginal bone loss and incidence of peri-implantitis compared with periodontally healthy subjects. Even though the short-term implant prognosis for patients treated for aggressive periodontitis is acceptable, on a long-term basis the matter is open to question. Alterations in clinical parameters around implants and teeth in aggressive periodontitis patients may not follow the same pattern, in contrast to what has been reported for chronic periodontitis patients. However, as only three studies comprising patients treated for aggressive periodontitis were selected, more studies, specially designed, are required to evaluate implant prognosis in this subtype of periodontitis. As the selected publications exhibited considerable discrepancies, more studies, uniformly designed, preferably longitudinal, prospective and controlled, would be important.

Factores de riesgo y periimplantitis en la terapia implantológica. Revisión narrativa.

“…Karoussis 22 encontró un diferencia no significativa en la sobrevivencia de implantes entre pacientes no periodontales y pacientes con periodontitis tratada. Sin embargo, sí reportó que pacientes con antecedente de periodontitis tratada presentaban una tasa significativa mayor de aumento de la profundidad de sondaje y de pérdida ósea marginal.…”

Microbiological Aspects Dental Implant- A Review

“…Although these bacteria were identified at tooth and implant sites the clinical parameters did not indicate progressive bone loss or implant failure. [24] These distinct differences between the edentulous and partially edentulous groups suggest that the presence of pockets around teeth, which harbor a large variety of bacteria, may serve as a reservoir of periodontal pathogens contributing to contamination of peri-implant sites. The longitudinal success of osseointegrated implants in edentulous patients may be due to a reduced intraoral challenge by implicated periodontal pathogens and, conversely, the presence of such pathogens in partially edentulous patients may conceivably hasten subsequent peri-implant disease if patients are not well maintained.…”

Microbiology of Dental Implants: A Review of the Literature

“…Karoussis et al 24 reported that patients with a history of periodontitis manifested significantly greater probing depths, more peri-implant marginal bone loss, and a higher incidence of peri-implantitis. Also, implants which display a gap between implant and abutment permits new bacterial colonization.…”
