Implant pros Flashcards
dental implant
an artificial tooth root that is surgically anchored into the jaw to hold a replacement tooth or teeth or a denture in place. The benefit of using implants is that they don’t rely on neighbouring teeth for support
implant relation to bone
no PDL
usually sits at crest of bone - placed and no bone loss
direct integration into bone - osseointegration
crown for implant attached
2
cement or screw
how many screws in implant
3 - so 3 potential areas for failure
implant itself
abutment screw
restoration screw
implants can restore
4
- A single tooth
- Multiple teeth
- Can secure a denture firmly (implant overdenture)
also Eyes, ears, hearing aids & noses
basic stages in implant placement
4
Raise and retract flap
Place implant
drill with sterile saline used to drill bone
Place cover scew
* don’t want bone to grow down hollow centre of implant so place a cover scew on top – some systems will have it through mucosa others suture on top
Suture
3months till prosthesis added, implant now integrated to bone
implant prosthetic stages for single tooth
Uncover implant (no need to raise flap, tissue pump with LA)
Place abutment
Take impression with coping
Choose colour
Place temp
Cast impression with lab dummy (working cast)
Cement/screw in final restoration
what type of cast is good to use for implant planning
soft tissue cast
mimics gingiva so can get good emergence angle around the implants
what secures denture firmly
Various ways to do this
locator abutments
ball abutments
gold bar
CAD-CAM titanium bar
less common - Novaloc abutment, magnetic retention
common post implant tx complications
4
Peri-implant mucositis
Peri-implantitis
Loose/fractured components
Late implant failure
how to deal with implant pt
same as normal pt
history, examine, tx plan (refer back to implant dentist if needed)
role of GDP in implant pts
Oral health advice
Triage and diagnosis (if possible) of a complication
Referral of the complication to an appropriately trained, indemnified and competent implant dentist
* Separate indemnity for implants – don’t touch them, OH and refer
Manage taking account of SDCEP guidelines
why CBCT for implant planning
benefit from 3D view - width of bone
why denture sometimes better than implant retained for complete arch
Denture over fixed gives full flange if complete lip support needed and hard with non removable prosthesis
role of healing abutments
place to allow gum to heal around after surgery before implant placed
