New Guide Orthodontic for Orthodontic Screw Screw Placement Please read and observe the following guide carefully for successful placement. Osstem Orthodontic Screw was developed by the R&D center of Osstem Implant to help your successful placement with its superior quality. 1. Drilling New Design Concept of the orthodontic screw, In this case, initial drilling is recommended. ● Good Initial Stability ● The placement methods using drilling process of the products are shown below; ● Good Self Drilling & Self ● Make Tapping sure to inject a saline solution during drilling to prevent overheating. ● Good Feeling of Screw ● The Implantation recommended drilling speed is 800rpm. ● Good Strength ● Small Head Size ● Simple Gingiva Shape ● The design of this product dose not require drilling before placement. However, if the bone is very hard, the excessive placement torque may lead to the failure ∅1.3 ∅1.3 Drilling Depth Only Cortical Drilling Depth Only Cortical 1.4 1.6 Using ∅1.3 Drill Ø0.8(022” Wire) (Soft Bone) (Normal Bone) (Hard Bone) Low Profile and Smooth Curved Head Simple Gingiva Shape ∅1.5 ∅1.5 1.8 Drilling Tapered Depth Body to Increase Only Cortical Bone Support Drilling Depth Only Cortical Using ∅1.5 Drill Strengthened Body Design (Soft Bone) Powerful Self (Normal Threading Bone) (0.7 Pitch) (Hard Bone) 2. Orthodontic Screw ● For manual placement, mount the Driver Tip on the Universal Handle, and connect the screw. Placement ● Turn in the clockwise direction Sharp tip with for force, at the initial placement speed of one revolution per five (5) seconds. When Self Drill thread Function begins to be formed in the bone, apply a rotating force only for further placement. ● When using an Engine, mount the Machine Driver on the Hand Piece, and connect Simple Head the screw. Place the orthodontic screw at the speed lower than Through 20rpm. Hole ● Insert the screw until the driver tip touches the gingival tissue, and then remove the driver. 02 12 MS Inplant System

Resistance against Orthodontic Forces 50 Resistance of the thread against external load To use orthodontic screws as a stable anchorage, the screw thread and bone must have sufficient resistance against orthodontic forces. The screw thread and body shape of the new product are designed to be highly rigid against orthodontic forces.

Connecting Distribution the ● It is recommended to install the devices (wire, power chain, coil spring, etc.) Orthodontic Devices for applying orthodontic force after one or two weeks from the screw placement to secure sufficient initial stability. The body and thread of the new orthodontic screw are designed to facilitate stress distribution. Thus, 5. Removing long-term the orthodontic Screwforce does ● To not remove give excessive a screw, stress fix the to driver in the hex head of the screw and turn the bone with the new orthodontic screw in the opposite direction of placement slowly. ● It is safer to use a Hex Driver for the products formed with a Cross Slot. Conventional : 35.3Mpa New : 23.8Mpa Using a Cross Driver may break the screw neck. Enhanced Body Strength 80 6. Using the Product ● The orthodontic screws are sterilized and can be placed directly after unpacking.
