historically, prefabricated abut-
ments have been a convenient and useful
treatment component for implant resto-
rations. Prefabricated abutments do not
require advanced technology for produc-
tion, but dentists have been unable to
easily customize them, making it difficult
to achieve optimal contours and esthetics.
Screw-retained or cement-retained
implants both offer unique advantages
and disadvantages, while research indi-
cates that there is no significant differ-
ence between the two types.
With continued controversy over the
best technique, both can be used for
successful treatments.

CASE STUDY
The patient presented with a failed
implant that resulted in a deficiency of
bone width and height, as seen in cross
sections of the GALILEOS scan (Sirona
Dental Systems, LLC) (Fig. 1). Performing
vertical augmentation or lateral augmen-
tation procedures for this patient were
contraindicated, since the mental
foramen existed exactly where the
the way implant abutments are fabricated
to support esthetic restorations.
In particular, all-ceramic abutments can
be designed via CAD/CAM techniques
and processed from a lithium disilicate
block (IPS e.max CAD, Ivoclar Vivadent)
to reduce the time and cost involved with
creating the ideal implant abutment. The
lithium disilicate glass-ceramic block is
milled to produce abutments designed
usingCERECsoftware(SironaDentalSolu-
tions, LLC). The customized abutments
are ideal for single-tooth restorations in the
anterior or posterior region, and previous
research regarding the lithium disilicate
material supports its clinical performance
in terms of strength and adhesion.
Once designed using the CEREC soft-
butment is milled and can
omized prior to placement.
