Q

Which is usually a better candidate for immediate
implant placement after extraction: anterior or
posterior

A

Anterior teeth because diameter of implant is

close to CEJ diameter of extracted tooth

Q

Why are posterior extractions not a good

candidate for immediate implant placement

A

posterior teeth have wider diameter than implant

so socket exceeds critical space of <2mm

short spans
31
Immediate implant placement is
placement of an implant at the time of tooth | extraction
32
Immediate loading is
placement of a restoration at the time of implant | placement
33
Should provisional restorations rest on bone grafts | or newly placed implants
no
34
Bone grafting works best to augment ridge height | or ridge width
Ridge width
35
) Gingival grafts should be performed prior to fabricating final restoration or after the final restoration is delivered
prior to fabricating final restoration
