Topway dental laboratory have an independent milling center which
service for not only dental labs from overseas, but China too. We
have the most full implant database in Chinal. This makes us have
the capability to meet almost all your implant needs.
Custom implant abutments produced from titanium and zirconia are
popular and afforadble choices for cement retained implant
restorations.Advancements in dental CAD/CAM and manufacturing
techniques make it possible to create patient-specific abutments
that are both strong and esthetic.
Titanium abutments are the workhorses of custom abutments.Their versatility and
robustness make titanium custom abutments the most widely
prescribed abutment of the three. They can be used in both the
upper and lower arches — for any tooth number — and their long
history of success is well documented in the dental literature.
Zirconia custom abutments are prescribed primarily in the anterior of the maxillary arch for
esthetic reasons.Because zirconia abutments are of all-ceramic
composition, there is no titanium to show through the soft tissue
or leave a dark central shadow in the crown. This makes them
particularly advantageous when dealing with thin tissue biotypes,
which may be subject to discoloration resulting from titanium
shading visible through the gingiva. Besides its excellent strength
and esthetic characteristics, zirconia exhibits hygienic properties
comparable to titanium.2,3 Another unique feature offered by zirconia abutments is the
ability to layer pink porcelain directly onto the abutment, when
necessary, to approximate the color of the surrounding soft tissue.
Zirconia custom abutments with a titanium connection, also known as zirconia “hybrid” abutments, are prescribed more often than all-zirconia abutments. With
hybrid abutments, a zirconia body is luted in the laboratory to a
short titanium connection feature — sometimes referred to as a
titanium base — to provide a titanium-to-titanium interface with
the implant platform. In most circumstances, this titanium
connection is very short and is not visible through the tissue.
Because the connection to the implant is made from titanium, these
abutments are compatible with the same abutment screws used in
titanium abutments. The titanium portion can also be color-coded
during the manufacturing process, providing a visual cue to help
immediately identify the matching implant platform.
With these prosthetic considerations in mind, the selection of an
abutment type is a matter of functional requirements and esthetic
needs.4 Titanium abutments can function anywhere in the mouth, but may, in
some cases, compromise the esthetics of restorations in the
anterior maxilla. Zirconia abutments can be placed anywhere in the
mouth, but are most advantageous when used in the esthetic zone.
