Anterior Implants (John Boy's)

Question 1

Overall survival and success rate similar to other areas of the jaw

Answer 1

Belser, 2004

Question 2

No differences in survival rates in reference to anatomical position

Answer 2

Eckert, 1998

Question 3

Implant success rate about 96% for ant maxillary implants

Also, found esthetic failure rate of about 9%

Answer 3

Henry, 1996

Question 4

Need bone for soft tissue scaffold (preserve it or create it)

Answer 4

Magne, 1993

Question 5

Peri-implant mucosal dimensions are greater in thick gingival biotype pts

Answer 5

Kan, 2003

Question 6

Long term esthetic stability relies on adequate ST volume in vertical and facial/lingual direction

Answer 6

Carrion, 2005

Question 7

The papilla is dicated by the interproximal bone height on adjacent natural teeth and final prosthetic contact. If its greater than 5mm = black triangle

Answer 7

Tarnow, 1992

Question 8

Papilla sparing incision

Answer 8

Nemcovsky, 1999

Question 9

Crest of bone to tip of papilla between implants is 2-4mm

Answer 9

Tarnow, 2003

Question 10

The papilla has NOTHING to do with the bone next to the implant, its the bone next to the tooth

Answer 10

Kan, 2003

Question 11

Restoration-driven

Answer 11

Garber, 1995

Question 12

Screwed abutment is best for maintenance and long term stability

Answer 12

Hermann, 2001

Question 13

If facial plate at leaset 1.8-2mm then significantly less facial vertical bone resorption

Answer 13

Spray, 2000

Question 14

Thin Biotypes need to have a more palatal placement

Answer 14

Buser, 2004

Question 15

Countersinking is dependent on the implant diameter (wider needs less as the emergence is almost already there)

Answer 15

Jansen, 1995

Question 16

With good OH, sub mucosal shoulders not exposed 4-9yrs later

Answer 16

(Giannopoulou, 2003)

Question 17

Peri-implant biologic width (“microgap”) is approx 1.5-2mm

distance from implant/abutment connection to crestal bone

Answer 17

(1.5mm)Cochran, 1997; (2mm)Herman, 2001

Question 18

Sink depth of the shoulder (without ging. recession) should be 1-2mm apically to imaginary line of mid-buccal CEJ’s of adjacent teeth. [may want to go deeper 2-3mm for 2 stage-Sabbagh]

Answer 18

Belser, 2000

Question 19

Timing of implant placement:
Immediate
Staged (at least 8wks po)
Delayed (3months or more po)

Answer 19

Garber, 1995

Question 20

Immediate: as much as 3-4mm of B/L and A/C bone resorption can happen 6months po

Answer 20

Atwood, 1971

Question 21

immediate placement preserves bone and ST

Answer 21

Sclar, 1999

Question 22

Immediate implant success rates are similar to those placed in healed sites

Answer 22

Rosenquist, 1996

Question 23

during extraction When possible avoid reflecting a flap; to minimize bone resorption

Answer 23

Wilderman, 1970

Question 24

“immediate” placement: f disseminated infection, wait about 3wks for healing and ST closure

Answer 24

Tischler, 2004

Question 25

If Jumping Distance is less than 2mm, no augmentation if rough surface implant is used

Answer 25

Buser, 1998; Paolantonio, 2001

Question 26

Garber Defect Class 1

Answer 26

Ideal ridge

Question 27

Garber Defect Class 2

Answer 27

no vertical bone loss; 1-2mm of horizontal bone loss | Summers technique to expand with Osteotomes

Question 28

Garber Defect Class 3

Answer 28

no vertical bone loss; more than 2mm horizontal | may still be able to place implant

Question 29

Garber Defect Class 4

Answer 29

no vertical bone loss; horizontal too much for single stage; need GBR

Question 30

Garber Defect Class 5

Answer 30

Vertical bone loss | tenting screws or use implant as tent
