CEMENTABLE RESTORATION
Titanium abutment
A cementable implant restoration closely resembles a traditional cementable restoration
and affords most of the time the best esthetic results.
Zirconia abutment
Minimum height requirement from the head of the implant to the opposing occlusal surface is 6 mm. Single crowns to a full arch restoration are possible. Another benefit of this type of
restoration is that the implant does not have to be in a perfect position to
work successfully. The draw back to a
cementable restoration is the inherent irreversibility, unless temporary cement
is used.
Restorative material ranges from full gold, porcelain fused to metal, to any all ceramic restoration.
PFM
After installation of the abutment on to the implant in the patients mouth, the crown is delivered
in the same fashion as any other cementable restoration.
The cement or bonding material is chosen
according to the restorative material (e.g. PFM, Lava a.o.).
Expect to spend
more time adjusting proximal and occlusal contacts because in most instances
no temporary restoration was fabricated and adjacent teeth might have shifted
from the time of impression taking to delivery.
e-max
The occlusal contact should be very light
to just out of occlusion because the periodontal ligament of the remaining natural teeth
allows the natural teeth to depress slightly during mastication in to their bony sockets and implants
don't have a periodontal ligament to allow movement. Only one occlusal contact directly over the implant
is recommended. No lateral interference of any kind to minimize off axis loading
of the implant.
