Spider Screw® System
Orthodontic Head
• Designed to facilitate appliance
(wires, springs, etc.) placement
• Features two intersecting .022" slots
• Under tie-wing area also functions
as another .022" x .025" slot
featuring two intersecting
slots of .027" in diameter
• Chamfered inlets simplify
insertion of wires or ligatures
• Small head dimension is designed
for patient comfort
Transmucosal Portion
• Variable length allows for
optimal adaptation to different
intraoral mucosa thicknesses
during bio-maintenance
• Short length for areas of thinly
attached gingiva
• Long for areas with thick or
freely movable tissues
• Polished with a special
treatment to help avoid soft
tissue irritation and make
cleaning easier to accomplish
EXCLUSIVE!
Intrabony Portion

asymmetrical profile for
easy placement

avoidance of bone stress
• Self-drilling and self-tapping
makes pre-drilling before
insertion unnecessary dependent
upon bone structure
• Easy to place while reducing the
risk of root damage

The Spider Screw’s geometry is a result of careful design in
every single detail. In fact, the Spider Screw has obtained
two international patents since its inception, due to its
innovative characteristics: the simultaneous presence of
the external and internal rectangular slots and round
internal slots.
The Spider Screw’s design is extremely versatile, due to its
small dimensions and unique design. It is easily placed in
either the maxilla or mandible, even where access is limited
and bone quality is less than ideal. Placement is simplified
by the self-drilling feature found in the K1 Plus, K2 Plus, K1
and K2 Spider Screw systems. Spider Pin requires pre-drilling.
The Spider Screw has been developed to offer a number of
versatile anchorage options capable of immediate loading.
Immediate loading is possible because the Spider Screw is a
non-osteointegrable implant and consequently force can be
applied immediately after placement. The applied force can
range from 50 to 300 grams depending on screw choice,
bone quality, and the desired orthodontic movement.
The Spider Screw is an anchorage device that can be used
during every phase of orthodontic treatment and is suitable
for symmetric or asymmetric anchorage. The Spider Screw
assists in the success of orthodontic treatment, both in
adults and adolescents, by reducing treatment times without
patient compliance.
The Spider Screw package includes three removable labels
containing important information (device name, reference
code, lot number, etc.) which is to be applied to the patient’s
record card for traceability. Our sterile packaging ensures
the Spider Screws are ready to use whenever you need them,
saving your office valuable processing time. The screws have
been cleaned, decontaminated and sterilized via gamma
radiation, simply use sterile handling protocol.
