Surgery Flashcards
Two different types of implants
tissue level
bone level
what type of implant are these
blue - tissue level
red - bone level
a difference between tissue level and bone level implants
tissue level - 1 stage technique
bone level - 2 stage technique
What does FEV stand for
finite element analysis
what does finite element analysis mean
transfer of load to surrounding bone tested by a mathematical model analysis
to avoid stress of the bone around the neck of the implant leading to bone loss
what is FEV affected by
implant body shape
implant collar shape
threads
grooves
material for implants
commericially pure titanium (available in 4 grades depending on the amount of carbon and iron)
roxolid
pure ceramic implants
Various timings of implant surgery
immediate
immediate delayed - soft tissue healing 4-8 weeks
delayed - partial bone healing 3/4 months
elective - full bone healing > 4 months
complications of implants
wound breakdown
infection
early loss
mucositis
peri-implantitis
how do you know when an implant has failed
if it is lost
mobile
shows peri-implant bone loss greater than 1mm in first year or greater than 0.2mm a year after
