Diagnostic Imaging and Techniques Flashcards
Principle to use in radiology:
ALARA
Rg tech becoming more common in implant dentistry:
CBCT
retrograde enodo fillings
surgeon goes through gingiva, removes apices of teeth, prepare a cavity within the tooth, fill with amalgam
% dentists, pano as sole determinant for implant tx planning:
90%
AAOMR says all implant site evals should be done via:
3D imaging (legal implications)
distortion rate in panos:
25%
How to measure whether there is 3mm bw implants in a pano.
you cant - 25% distortion rate
Panos include this in image:
sinuses, man canal, bone topography, teeth
When to take PA:
planning, surgery, restorative, maintenance
During an osteotomy what is placed in the bone?
direction pin, mimics surgical guide as close as possible
When to decide whether RG guide is accurate:
Try in for RG guide & RG to check angulation
What is placed that mimics the surgical guide as close as possible?
direction pin
What is the most accurate imaging we can take
PA, more than CBCT
Why would a direction pin not be placed to depth?
in order to slightly change angulation (check?)
Drug that can cause osteonecrosis of jaw:
bisposphonates (women, osteoporosis, cancer, leukemia)
Issue w implant place to close to adjacent teeth:
emergence profile too lose
Why is the preservation of a tooth adjacent to an implant site so important?
No adjacent tooth = bone loss
Teeth that can be placed into the nasal fossa
any anterior? Can canines be placed here?
how to correct placement if accidentally pierced through nasal fossa
OS or ENT
What does it mean if you see a thin part bw two metallic pieces of the implant:
abutment was not fully seated in implant
What are you checking for in follow up RG of implant:
bone level in relation to threads
CBCT can be used for:
Tx planning, bone quality (1-4)/ quantity, relationship w surrounding anatomy, post-surgery
8, type of bone at location?
3
5, type of bone at location:
4
