Anterior Implant Planning Flashcards
Distance needed between tooth and implant and implant to implant?
1mm between tooth and implant
3mm between implants
Standard size implants for maxillary centrals, laterals and canines
about 4mm for centrals and canines
less than 4mm for laterals
depth of implant
2-3mm apical to zenith of adjacent teeth
Interproximal distance of implant
1-1.5mm from adjacent teeth
Labial-lingual placement
2mm palatal to labial bone surface (need 2mm of buccal bone)
healing time for implant
Mandible 3 months
Maxilla 6 months
After uncover and before final impression, how long should we let the tissue heal?
Posterior: 2 weeks
Anterior: 3-5 weeks
Is closed or open tray impressions better for single tooth implant?
Both the same
Which impression technique is more accurate with multiple impressions?
Open tray
What type of crown retention should we use for implant provisionals?
Screw to avoid excess cement
Does a cantilever off an implant lead to more bone loss or increased failure of implant?
No, but more technical complications
3 types of implant abutments
- Titanium
- One-piece Zirconia
- Zirconia with Ti insert
Is there a difference between Ti and Zr abutments?
No. Only difference is seen biologically with Zr due to excess cement
What abutment should we use when soft tissue is thin?
Zr
What is the distance between contact and bone height that will guarantee the papilla to fill embrasure?
5mm
