points indicated by Dr. Susin and from review

Question Answer
Extreme _______ is a contraindication for sinus augmentationPneumatization (could be that this in not a contraindication... long list of contraindications and this is not included in lecture... but is listed under concerns of indication *shrug*)
when managing a sinus membrane perforation, you should work from ____ to ____ (in & out- these are your choices)work OUT to IN
The gap between a socket and an implant during an immediate placement into socket should be less than or equal to ___ mm2 mm
What is the ideal width of a canine implant4mm
Sven johanson's implants have been in place for ___ years50 years
____ is a new implant material and can be used for better esthetic outcomeszirconia
Implant osseointegration requires formation of the ____ ____ layertitanium oxide
probing depths around implants should be expected to be ______ compared to normal probing depthsdeeper
If an implant is placed in a growing patient, the implant restoration will ultimately be in _____-occlusion once growing is completeINFRA-occlusion
what percentage of extractions have the complication of buccal bone loss?1/3 (33.3%)
t/f: shorter implants have lower survival ratestrue
t/f: shorter implants have higher survival ratesfalse
how much horizontal bone loss would you expect from the buccal bone following extraction?4 mm (stern's lecture said 2, though... we've gotten different numbers here * shrug*)
___mm of bone around implant is needed for immediate implant placement2 mm
when comparing implants to teeth at a 10 yr mark... which has the lowest survival rate?implant
t/f: at the 10 yr mark, endo-treated teeth and implants have similar survival ratestrue
platform switching can only reduce marginal bone loss by ___ mm around a dental implant0.5 mm
What is the minimum B-L ridge width for regular implant (4mm wide)6 mm (1 mm bone minimum + 4 mm implant + 1 mm bone minimum)
What is the ideal B-L ridge width for 4 mm implant?at least 8 mm (2 mm bone + 4 mm implant + 2 mm bone)
What is the minimum interdental (M-D between roots) distance for 4mm implant7mm minimum (1.5 mm M + 4 mm implant + 1.5 mm D)
What is the ideal interdental (M-D between roots) distance for 4mm implant8 mm ideal (2 mm M + 4 mm implant + 2 mm D)
Minimum B-L ridge widthe for regular implant (4 mm wide) should be ____ mm6 mm
What changes in the implant neck characteristics can prevent marginal bone loss after implant placement?Platform switching (0.5 mm) (although old lectures say none)

Bone Quality/Quantity

Question Answer
homogenous & compact: Type ___Type 1
thick cortical surrounding dense trabecular core: Type ___type 2
thin cortical, dense trabecular core: Type ____type 3
thin cortical, low density trabecular core: Type ___Type 4
which Type is least favorable for implant placement?Type 4
which Type is most favorable for implant placement?Type 1
What Quantity grades are common in the mandible?A, B, C
What quantity grades are common in the maxilla?D & E
Grades such as A, B, C, D, E indicate bone _____ while types 1-4 indicate bone _____quantity; quality
What is the combination of grades for quantity and quality that are the LEAST favorableType 4, D or E (most prone to failure)
T/F: an advantage of immediate implant placement is that it prevents bone resorptionFalse (fewer procedures only advantage)
what is the hallmark sign of per-implant mucositis?bleeding on probing
what is the hallmark sign of peri-implantitis?bone loss
Sinus has really thin walls... what is the best approach?Lateral Window approach
Sinus has really dense trabeculae... what is the best approach?Osteome/Summers approach
T/F: implants are moving toward having a wider diameter and emergence profileFalse

What is the ideal and minimum space between implants and....

Question Answer
B/L plate2 mm (ideal); 1 mm (minimal)
another implant (inter-implant)3 mm (ideal) 2 mm (minimal)
tooth2 mm (ideal) 1.5 mm (minimal)
"vital structure"2 mm (ideal) 1 mm (minimal) (this is questionable, there are many exceptions such as the IAC or Mental foramen)
mucosa coronal to implant2mm
space beyond apex of socket to place implant3-4mm
shortest usable implant length6mm
common implant length8mm
ideal length of implant (widely currently accepted lit, not what will change to)10 mm
