Basic Surgical Protocols for Implant Placement Flashcards
there should be at least …. mm between 2 adjacent implants and at least … mm between an implant and adjacent tooth
3mm
2-3mm
there should be at least … mm of interocclusal distance from the top (shoulder) of the implant to the occlusal surface of the opposing tooth
7mm
when placed in mature bone, implants should have at least … of bone on all sides
1mm
… implants are preferred in the posterior sextant
wider
in general, … and … implants are needed in denser bone
fewer and shorter
… and … implants are needed in patients who grind or clench their teeth
wider and longer
what are the four placement types of implants (based on timing)
immediate
early
late
conventional
… placement is when the implant is placed in a site where the soft tissue has healed and a mucosa is covering the socket entrance
early
…. placement is when the implant is placed in an extraction site at which substantial amounts of new bone have formed in the socket
late
… placement is when an implant is placed in a fully healed ridge
conventional
advantages of immediate implant placement
less surgeries
less overall tx time
optimal use of existing bone
disadvantages of immediate implant placement
site morphology may complicate it tissue biotype may compromise outcome potential lack of ker. mucosa for flap adapt. adjunc. procedures may be needed technique-sensitive procedure
advantages of early placement
easier flap adaptation
allows resolution of local pathology
disadvantages of early placement
site morphology may complicate it longer tx time varying amt of resorption at socket walls adjunc procedures may be needed technique-sensitive procedure
late implant placement is usually at least … weeks out
16
advantages of late placement
clinically healed ridge
mature soft tissues; easier flap management
disadvantages of late placement
increased tx time
adjunc procedures may be needed
large variation in available bone (increased bone loss with longer waiting time)
For immediate and early implant placement:
In sites where available bone height apical to the socket is less than …. it is frequently impossible to obtain primary impant stability
3 mm
For immediate and early implant placement:
…. plays a major role in immediate and early implant placement indications
soft tissue biotype
For immediate and early implant placement:
… out of 4 socket walls have to be intact w/ or w/o dehiscence or fenestration on buccal wall
3
For conventional implant placement: the rate of new bone formation decreased after …. of healing
3-4 months
4 preop procedures for implants
antibiotic prophylaxis (2gm amoxicillin)
NSAIDs
sedation (IV or oral)
CHX rinse 30 before
apicocoronally, the implant shoulder should be placed … apical to CEJ of the adjacent teeth in patients w/o gingival recession
2 mm
3 advantages of one-stage implant placement
no secondary surgery to uncover implant
better evaluation of wound healing
allows early temporization
2 disadvantages of one-stage implant placement
exposure to oral cavity during osseointegration period
difficult to control loading especially with removable temporary restoration
3 contraindications for 1 stage implant placement
primary implant stability is less than ideal
smokers
thin tissue biotype
… implant placement is when the mucosal flap can be adapated to the neck (healing cap) of the implant
1 stage
… implant placement is when the mucosal flap is sutured on top of implant (cover screw) obtaining primary wound closure
2 stage
Pros of immediate/early implant placement with a single rooted tooth
single socket easier extraction adequate soft tissue manageable gap root length (shorter)
Cons of immediate/early implant placement with a single rooted tooth
oval shape socket
rotated tooth
esthetic zone
anat. landmarks
root length (canines)
Pros of immediate/early implant placement
intact large septum if roots were divergent
non-esthetic zone
Cons of immediate/early placement for multi rooted teeth
more than one socket
lack of tissue adaptation
heavy occlusal forces
anat. landmarks
