tes the height of the impl

nt needed to fill
the void. Use the preoper

a
nd the following tips
for e
a
se of impl
a
nt selection:
– The height of the impl
a
nt in its st

rting position should
b
e
less th
a
n the undistr
a
cted corpectomy height.
– Su
b

to
a
ccount for the height of the three t
a
llest spikes.
– The m
