Sabbatini Flashcards
)Surgical steps for implant placement
reflect flap Twist drill 1.5mm Direction indicator Tapered drill 3.5 mm Direction indicator Tapered drill 4.3 mm Implant placement
Who steers the multidisciplinary implant case
Restorative dentist
5 roles of implant surgeon
initiate or assist treatment planning Perform site preparation surgery Perform fixture placement surgery Assist with impression and temporization Treat ailing & failing implants
)7 relative Systemic Health contraindications for
implant surgery
uncontrolled diabetes Severe immunodeficiency Uncontrolled vascular disease Heavy smoking Alcoholism Post-irradiated jaws Bisphosphonates (Fosamax)
3 spaces to evaluate clinically before implant
Mesial-Distal
Buccal-Lingual
Interarch (w/ teeth in MIP)
184.) 8-9mm
3.75 to 4.3 mm implant + 1 mm bone B + 1mm bone
Lingual + 1 mm soft tissue B + 1 mm soft tissue lingual
Which crown type requires less interarch
space
screw retained
What is the minimum interarch space and
numbers that make it up
- 0 m
5. 0mm abutment + 2.0mm crown thickness
)If have all the available spaces, what space can still
contraindicate implant placement
pt cannot open enough for implant surgical
hardware
Minimum distance required for surgical hardware
35mm
What does a periapical radiograph show for
implant planning
periodontal status
Periapical status
Root alignment
Mesio-distal space
)3 major things seen on Panoramic for Implant
planning
Bone volume
Bone morphology
Anatomical concerns
Anatomic structures concerned with for implant
planning that can be assessed radiographically
Nasal floor
Maxillary sinus
Mandibular canal
Mental foramen
)what is the distortion on a PA radiograph
0-10%
What is the distortion on a Panoramic radiograph
25-30%
What should be done when treatment planning an
implant in the vicinity of the mental foramen
add a few mm anterior to allow for the nerve loop
CT scan gives what information
anatomic info and bone density
Regular platform implant used in what areas
Maxillary central incisor Maxillary canines Maxillary premolars Mandibular canine Mandibular premolars Some molars
what is the diameter or regular platform implants
4.0-4.5 mm
Wide platform implants used in what areas
4.0-4.5 mm
Wide platform implants used in what areas
Molars
What is the diameter of wide platform implants
) 5.0-6.0 mm
Narrow platform used in what areas
Maxillary lateral incisors
Mandibular incisors
Some premolars
What is the diameter of narrow platform implants
3.0-3.5 mm
When determining placement angle for implant,
what should be drawn on casts
Adjacent tooth roots
3 considerations for fixture position
apical enough for emergence profile
Slightly palatal for gingival bulk
> 1.5-2.0 mm from adjacent roots
2 things tapered implant does
allows missing adjacent roots
Wider portions compress bone to make it more dense
How long after atraumatic extraction to wait if
doing delayed fixture placement
4-6 months
3 criteria for immediate implant placement after
extraction
absence of infection
Sufficient residual socket walls
Adequate bone for primary stabilization (lateral &
apical
) Socket preservation synonymn
GBR = Guided bone regeneration
Majority of implant misadventures can be
attributed to
lack of attention to detail in diagnosis and
treatment planning phase
