Periodontal Maintenance for Implant Patients Flashcards
What bacteria are responsible for peri-implantitis ?
GRAM NEGATIVE ANAEROBES
P. Gingivalis.
Bactericides forsythias.
P. intermedia.
Fusbacterium nucleatum.
Staphylococcus.
What are the causes of peri-implantitis ?
Poor OH and periodontal status.
Impaired host defence.
Poor implant design.
Operator placement.
Excessive mechanical forces.
Excess residual cement.
Define peri-implantitis.
Inflammation of hard and soft tissues surrounding osseointegrated implant and subsequent progressive loss of supporting bone.
What are the signs/symptoms of peri-implantitis ?
Increased probing depth with BoP.
Suppuration.
Mobility.
Radiographic loss of bone height.
Inflammation of mucosa.
Define peri-implant mucositis.
Reversible inflammation affecting peri-implant soft tissues without bony involvement.
Definition -
Presence of bleeding and/or suppuration on gentle probing with or without increased PD (compared to previous appointments).
Absence of bone loss beyond crestal bone level changes resulting from initial bone remodelling.
What are the signs of peri-implant mucositis ?
Inflammation and erythema of mucosa.
Bleeding on gentle probing.
+/- suppuration.
No radiographic sign of bone loss.
Increased probing (false pocketing).
Define peri-implant health.
Absence of clinical signs of inflammation.
Absence of bleeding or suppuration on gentle probing.
No increase in pocket depth (vs. baseline, <5mm).
Absence of bone loss beyond crystal bone level.
Where you don’t have baseline data, what are the criteria for suspected peri-implantitis ?
Presence of bleeding and/or suppuration on probing.
Probing depths >6mm.
Bone levels >3mm from most coronal portion of the intraosseous part of the implant.
What probe should you use when probing around an implant ?
PCP12 or UNC15.
What are the predisposing factors for peri-implant disease ?
History of severe periodontitis.
Poor plaque control.
No regular supportive peri-implant care.
Smoking.
Diabetes.
