PROTOCOL USE OF EXCALIBUR ORTHODONTIC SCREWS
1. DRILLING (IN HARD BONE)
›› The “Orthodontic Screw” design do not require
drilling before placement. However, we recommend
initial drilling on hard bone to avoid failure due to
excess in insertion force.
›› Placement after drilling just cortical bone.
›› We recommend to use 1.3mm drill for 1.6mm screw
and 1.5mm drill for 1.8mm screw.
›› Placement after drilling full screw length. It is desired
to drill in full as screw length at hard bone. However,
as !apless drilling is normal procedure, it makes you
easy to drill to the desired marking line considering
thickness of gingival. Then the whole insertion depth
will be total drilling depth plus 2mm.
›› We recommend using saline while drilling to avoid
over heating. Recommended RPM is 800.
2. PLACEMENT
Place a screw on the driver.
When you place a screw using universal driver, start
to apply force in the direction of placement. Once
internal threads are created, place the screw using just
torque.
Sustain 20rpm when machine driver is used.
Place a screw until the end of hex driver reaches
gingival and then remove the driver.
Proper insertion torque guide. Standard insertion
torque : 5-10Ncm
1) Hard Bone: Use 1.6mm diameter screw with 1.3mm
drill. Use 1.8mm diameter screw with 1.5mm drill.
2) Soft Bone: Immediate placement is possible without
drilling.
3. USING CONNECTION DEVICES
For securing initial stability, connection
devices (wire, power chain, coil spring, etc) only 2
weeks after screw position can be placed.
4. SCREW REMOVAL
To remove the screw, place driver onto the screw
head and turn counter-clockwise slowly.
To remove the screw, when the hex of the screw is
covered by soft tissue, use cross driver to turn and
remove it using hex driver. Excess torque using cross
driver can cause the fracture of the neck (hole area).
5. STERILIZATION
Our orthodontic screws are not sterile and must be
sterilized as indicated in the instructions sheet.
