Q

peri implant mucositis in patients that are not adhering to supportive implant therapy is as high as:

25
patients that adhered to a strict maintenance protocol had a prevalence of peri implantitis in the range of:
20%
26
in partially edentulous patients a lack of adherence to SIT within the overall patient sample was associated with onset of peri implantitis with an odds ratio of:
5.92
27
what is considered in material and surface characteristics of implant components
- evidence on the effect of implant surface roughness peri implant mucositis is limited - studies looking at highly machined implant abutments and bleeding on probing showed little difference - there was no difference in BOP between titanium and zirconium abutments either
28
accessibility of biofilm removal around implant supported prosthesis plays an important role in:
the prevention and management of peri implant diseases
29
the location of the implant margins has an impact on:
inflammation with supragingival margins being associated with decreased inflammation
30
is grafting of keratinized mucosa necessary to maintain peri implant health
no
31
what is excess cement associated with
- clinical signs of peri implant mucositis - higher prevalence of peri implant mucositis in patients with cemented prostheses compared to screw retained prostheses
32
what is peri implant mucositis
an inflammatory lesion of the peri implant mucosa in the absence of continuing marginal bone loss
33
what is peri implant mucositis caused by
a disruption of host microbe homeostasis at the implant mucosa interface
34
peri implant mucositis is a ____ condition at the _____
reversible; host biomarker level
35
what are the factors associated with peri implant mucositis
- biofilm accumulation - smoking
36
what is an important preventive strategy for peri implant mucositis
regular supportive peri implant therapy
37
what is the tissue response to microbial challenge at the 3 week mark
inflammatory lesions in the gingiva and peri implant mucosa - similar location, size and apical extension
38
what is the tissue response to microbial challenge at the 3 month observation
- similiar composition to 3 week observation but different apical extension - peri implant mucosa extended further apically
39
what is peri implantitis
a more advanced inflammatory disease that exhibits deep probing depths (greater than or equal to 5mm), BOP, and/or purulence, and radiographic evidence of peri implant bone loss beyond that typically associated with remodeling during healing
40
peri implantitis is a ___ condition occurring in _______ chracterized by_______
pathological; tissues around dental implants; inflammation in the peri implant mucosa and progressive loss of supporting bone
41
what are the clincal findings in peri implantitis
- soft tissue inflammation - BOP - progressive bone loss as noted on the radiographs
42
determination of prevalence of peri implantitis is complicated by:
- methodology: diabetic vs non diabetic, compliance to maintenance, smoker vs non smoker - definition of peri implantitis - PD greater than or equal to 6mm, 2.5mm radiographic bone loss, BOP or suppuration - number of exposed threads afer 1 year or longer of occlusal loading - diversity of implant designs
43
the prevalence of peri implant diseases showed that _____ of peri implant tissues had some form of inflammatory response and a prevalence of peri implantitis from _____-
90%; 28-51%
44
patients with a hx of periodontitis exhibited ____ prevalence of peri implantitis vs ____ for those with a negative hx of periodontitis
38%;11%
45
smoking increases the chance of peri implantitis by____ and mucositis by_____
31.6 or 3.8
46
existing peri implant mucositis is a significant risk factor for development of:
peri implantitis
47
what is the average prevalence of peri implantitis
28-51%
48
what are the significant risk factors for peri implantitis
- hx of periodontitis - poor OH - residual cement - smoking - genetics - diabetes - occlusal overload - residual PD of 5mm or greater with BOP - peri implant mucositis - existing peri implantitis
49
personal hygiene must begin at_____ and modified with _______
the time of implant placement; use of oral hygiene aids to clean the peri implant region
50
what do interproximal brushes do
penetrate up to 3mm into a ginvial sulcus and effectively clean a periimplant sulcus
51
what must be examined during the maintenance visit
- peri implant tissue margin - implant body - prosthetic abutment to implant collar connection and prosthesis
52
what should be used when treating a failing implant
- remove contaminated surface if present - citric acid/EDTA/tetracyline - ultrasonics - topical tetracycline - surgical repair if indicated
53
what is done in surgical repair of implant
- osseous grafting/GBR - remove implant from function - remove implant - more common now due to better explantation kits

at the histologic level compared to periodontitis sites peri implantitis sites have:
larger inflammatory lesions
55
surgical entry at peri implantitis sites often reveal a ______ pattern of bone loss
circumferential
56
data identifying smoking and diabetes as potential risk factors/indicators for peri implantitis are:
inconclusive
57
there is some limited evidence linking peri implantitis to other factors such as:
- the post restorative presence of submucosal cement - lack of peri implant keratinized mucosa - positioning of implants that make it difficult to perform oral hygiene and maintenance

rare event
