Peri-Implantitis Diagnosis and Prevention Flashcards
“a p l a q u e - a s s o c i a t e d p a t h o l o g i c c o n d i t i o n occurring in tissue around dental implants, characterized by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone”
peri-implantitis
Absence of erythema, bleeding on probing, swelling and suppuration.
Peri-implant health
Caused by plaque accumulation. Presence of inflammation. Reversible condition. Precursor of peri-implantitis.
Peri-implant mucositis
Caused by plaque accumulation. Presence of inflammation. Loss of supporting bone. Non-reversible condition.
Peri-implantitis
Long junctional epithelium attached implant ~ __mm long via basal lamina and hemidesmosomes
about 2 mm
t/f: connective tissue relationship to implant contains all of the following:
- Parallel, circular “cuff-like” fiber bundles
- does not embed into the implant
- A space of 20nm wide proteoglycan layer
- Collagen rich but cell poor
ture
is it the tooth or the implant that is cell rich, but collagen poor?
the natural tooth
Which has a greater supracrestal tissue attachment level?
natural tooth? or implant???
implant
What is the bio width of an implant?
3.6-4
What is the bio width of natural tooth?
about 2 mm
What is the appropirate probing pressure?
0.25 N
Which has the following: tooth or implant
- PD: 2.9 mm
- Buccal mucosa thickness 2mm
- shorter papilla height
- less papilla fill
implant
Which has the following: tooth or implant
- PD: 2.5 mm
- buccal mucosa thickness: 1.1 mm
- longer papilla height
- more papilla fill
natural tooth
t.f: Implant patients have less awareness of occlusal interferences
true
how wide it the PDL space on natural tooth?
PDL space ~ 0.2mm
t/f: Va s c u l a r i t y i n p e r i - i m p l a n t g i n g i va l m u c o s a i s l i m i t e d Vascularity in connective tissue under sulcular/junctional epithelium is similar Inflammatory response to plaque is the same way
true
t/f: Peri -implantitis contained larger Periodontitis Peri-implantitis proportions of neutrophil granulocytes and osteoclasts than in periodontitis
true
Stronger in flammatory response was around implants than teeth; need ______ time to complete reverse peri- mucositis than gingivitis
longer
is probing safe around implants?
yes sir
There is a positive correlation betweenbleeding on probing and histologic signs of______ at peri-implantsites.
inflammation
What are the three characteristics of implaned-protected occlusion?
- Occlusal contact position - No occlusal interference - Timed occlusal contacts
(light contact)
< ____mm bone loss per year after the 1st-year loading
< 2mm bone loss starting after loading
<0.2 mm
< 0.2mm bone loss per year after the 1st-year loading
< mm bone loss starting after loading
<2mm
How often do you do a radiographic check up for an implant if there is no pathology present:
Initial placement: 6 months, 12 months, and every 2 years if no pathology present.
How often do you do a radiographic check up for an implant if there is pathology present?
Initial placement: every 6 months if pathology present.
Can you save an implant that has lost osseointegration??
no ma’am
Patients with history of periodontitis with
acceptable self-care: ____-month recare interval
3 month
Patients with no systemic or local risk factors:
_____ month recare interval
6 month
