Restorative Implant Dentistry II

Question 1

Options for anterior single tooth replacement:

Answer 1

Traditional, resin bonded, OR cantilever FDP (for missing lateral incisor), removable, acid-etched, implant

Question 2

When are cantilevered FDP’as used?

Answer 2

for missing lateral incisors

Question 3

4yr success rate of Max single tooth implants:

Answer 3

97%

Question 4

8ys survival rate of Max single tooth implants:

Answer 4

97.5% (? Greater than 4y?)

Question 5

Influencing factor of tx for Max single tooth implants:

Answer 5

age, compliance, fear, esthetics, biologic complications (damage to adjacent teeth), pt availability, cost, open contact bw implant & adjacent teeth

Question 6

Contributing factors to Max anterior single tooth replacement:

Answer 6

craniofacial growth, transeptal fibers, occlusal forces, interproximal wear(?), contact surfaces (size, location) root angulation, crown ht, occlusal relationship, MD space at crown and bone level, available bone ht/ BL width, transitional prosthesis, soft tissue drape type-surrounding gingival tissues

Question 7

When is age a large factor when decided to place an implant:

Answer 7

further growth, esp. continuous eruption of adjacent teeth, esp pts w short or long face

Question 8

gingiva type that reacts to disease w pocket formation and infrabony defect formation

Answer 8

Thick

Question 9

gingiva w min attached gingiva:

Answer 9

thin

Question 10

thick gingiva:

Answer 10

flat, bony architecture, dense, fibrotic, lots of attached gingiva, thick underlying osseous form, resistant to acute trauma, reacts to disease w pocket formation and infrabony defect formation

Question 11

Thin gingiva:

Answer 11

scalloped soft tissue and bony architecture, delicate, friable, min attached gingiva, thin underlying bone characterized by dehiscence and fenestration, reacts to insults & disease w gingival recession

Question 12

High-scalloed gingiva is characterized as:

Answer 12

thin, high esthetic risk

Question 13

Gingival esthetic risk factors:

Answer 13

reduced IS, heavy smoker, high lip line, high-scalloped, thin gingiva, triangular shaped crowns, acute infection, 7+mm to contact point, restored adjacent teeth, 2+ missing teeth, soft-tissue defect, vertical bone deficiency

Question 14

Crown shape that is low risk for esthetic complications;

Answer 14

rectangular

Question 15

Medium esthetic risk pts:

Answer 15

Light smoker, medium lip line, medium-scalloped, meduium-thick, chronic infection at implant site, 5.5 to 6.5mm to contact point, less than 7mm for 1 tooth, less than 5.5mm for 1 tooth, horizontal bone deficiency

Question 16

How many mm below the facial CEJ of the adjacent teeth should the midrcestal position of the edentulous site be?

Answer 16

2mm below the facial CEJ of adjacent teeth

Question 17

How much more scalloped should the interproximal bone be than the midcrestal position?

Answer 17

3mm

Question 18

The FP width of bone at crest for an anterior implant should have at least:

Answer 18

1.5mm on facial + the dimension of the implant at the crest module, plus 1mm on the palatal (I thought 1.5mm on each side!)

Question 19

determines position of periimplant soft tissue?

Answer 19

biological width, biotype, width & ht of surrounding bone

Question 20

What affects the biological factors?

Answer 20

type of flap, position of implant, prosth factors

Question 21

Dominant factor in interproximal papilla:

Answer 21

tooth-side bone level

Question 22

Max distance in mm from contact point to crest of bone for the papilla to still be present:

Answer 22

5mm, at 6mm only 60%

Question 23

Interelement distance that most frequently results in adequate papillary fill:

Answer 23

3mm, must be AT LEAST 1.5mm

Question 24

How we do presurgical planning:

Answer 24

clear suck down over model, mark ideal line of placement on suck down, bone sounding, drill hole in cast to desired length, place hollow cylindrical guide in cast and through suck down, extend line through implant placement site on B and L
