FOUND Implants

Question 1

what is an implant

Answer 1

titanium screw that is placed into alveolar bone
can be used to replace single tooth or multiple teeth
osseointegration occurs with alveolar bone to secure implant in place and then porcelain structure added

Question 2

natural tooth vs implant

Answer 2

natural tooth;
-disease gingivitis or periodontitis
-mobility is reversible
-cementum, periodontal ligament and bone makes up tooth
-greater vascularity

implant;
-disease peri mucositis or peri implantitis
-mobility irreversible
-osseointegration into bone
-less vascularity

Question 3

implant component

Answer 3

crown
abutment
screw
fixture

Question 4

advantages

Answer 4

replaces teeth
no damage to adjacent teeth
replace denture
preserves bone
fixed in position
better functionality

Question 5

disadvantages

Answer 5

expensive
requires surgery
risk of failure
peri implant disease
insufficient bone level

Question 6

control of risk factors like

Answer 6

plaque control
no smoking
no periodontal disease
diabetes
aware of long term commitment
sufficient bone level or suitable for grafting. <8mm height min
suitable occlusion
motivated

Question 7

types of dental implant

Answer 7

single tooth dental implant
implant supported bridge
implant supported denture

Question 8

bisphosphonate

Answer 8

drug used to treat calcium deficiency
could make it hard to drill into hard bone, causing splinters

Question 9

types of implant system

Answer 9

tapered vs straight
thread depth/design
shirt <8mm vs long >8mm
treated surface vs machined surface
tissue level vs bone level

Question 10

tissue level implant

Answer 10

connection between implant and abutment rests at tissue level
improved accessibility to clean
wider platform, narrower body
natural looking tissue posteriorly
single stage placement

Question 11

bone level implant

Answer 11

implant fully submerged into bone
abutment attachment separate
more flexible for abutment design

Question 12

restoration retention

Answer 12

screw retained;
-requires sufficient bone level
-no risk of cement in subgingival crevice

cement retained;
-improved aesthetics
-no screw access cavity
-occlusal loading
-risk of cement in crevice

Question 13

healthy implant

Answer 13

no probing over 6mm
no sign of bleeding
no bone loss
good occlusion
no mobility
no exudate (no puss)

Question 14

treatment

Answer 14

good ORA
PMPR entire dentition including implant
no ultrasonic scalers because metal can damage implant
control risk factors
-bruxing (grinding)
-smoking
-hormonal factors
-glycaemic control

Question 15

peri mucositis

Answer 15

reversible
erythema (redness of gums)
bleeding
oedema (swelling)
probing 4mm and over
no bone loss

advise good OHR
antibiotics do not help. prescribe oral probiotics or chlorhexidine gel- stains teeth! inform patient

Question 16

peri implantitis

Answer 16

irreversible
in tissue around dental implant
inflammation
probe depth deeper than 6mm
oedema (swelling)
erythema (redness)
possible mobility
