The corresponding Sirona Scanpost
andScanbodywere theninserted(Fig. 9),
and a digital impression of the implant
was obtainedwith theCERECOmnicam
(Fig. 10). A one-piece screw-retained
restoration was then designed in the
CEREC Chairside software following
the same contours as the preoperative
digital restorationdesignwiththeexcep-
tion that this restorationwas designed to
be completely out of occlusion (Fig. 11).
An Ivoclar Vivadent IPS e.max Hybrid-
Abutment-Crown block (Fig. 12) was
utilized to mill the screw-retained resto-
ration, which was bonded to the corre-
sponding Sirona TiBase with the Ivoclar
Vivadent Multilink Hybrid Abutment
cement after crystallization and then
polished, stained and glazed accordingly
(Fig. 13). This one-piece, screw-retained
e.max implant restoration was then
screwed into the implant, hand tightened,

and the screw access hole was sealed
with Teflon tape and a small composite
restoration. The occlusion was care-
fully assessed to ensure that there were
no contacts with this immediate provi-
sional restoration during any centric
and excursive movements (Figs. 14-15).
