ARTO® FACEBOW WITH SYMMETRICAL PARALLEL ADJUSTMENT, COMPATIBLE WITH THE ARTEX SYSTEM
THE ARTO® FACEBOW
The practical Arto facebow allows safe and time-saving determination of the arbitrary hinge axis. The experience made over decades has confirmed that model assembly in the articulator via facebow can reduce grinding times considerably when integrating dentures.
Furthermore, the correct positional relationship of the arbitrary axis to the maxilla is of functional diagnostic relevance.
INSTRUCTIONS FOR USE FOR THE ARTO FACEBOW
This face-bow is a precision instrument that may only be used by trained dentistry staff. The product may only be used on skin or mucous membranes that have not been injured. We accept no liability for improper use.
Please take care when using the bite fork. Introducing it too deeply into the oral cavity or in an improper way can lead to injury. When placing the face-bow on the patient, please take care to avoid injury to the patient in the area of the ear canals.
Cleaning and Care:
For all parts of the face-bow and the accessories, in general please use only alkali-free disinfectants and detergents that are suitable for light metals!
Ear pads, nose bridge, nasion adapter After disinfecting, rinse under running water in order to remove traces of disinfectant.
Preparing the bite fork Use a spray disinfectant or a disinfectant bath. Sterilization in the autoclave is not a problem.
1. Pre-assemble as much of the face-bow as possible. Push the nose bridge backwards and pull lightly with the fixing screw. Make sure the joint support’s toggle screw is pointing to the right, then place it firmly on the face-bow and pull gently. Unscrew the fixing screws on the face-bow, and open the bow by pulling it apart.
Tip: Only open the toggle screw as far as is possible so that the support can still be moved easily. A quarter turn is usually sufficient for this. This way, the toggle screw will grip straight away during fixing.
2. Cover the bite fork with a substance such as thermoplastic in at least 3 places. If necessary, the thermoplastic or the prepared bite fork can be warmed up in advance. Press the bite fork against the teeth of the upper jaw so that light impressions are made in the thermoplastic. Warning: The teeth must not touch the metal of the bite fork!
3. The bite fork can be placed in the mouth by placing cotton wool underneath it near the molars, or with the help of the patient.
4. Place the pre-assembled, opened face-bow onto the patient. Place the ear pads of the face-bow onto the patient’s external ear canals, and carefully push the bow together while lightly pulling on the bow’s fixing screws. Place the glabella support onto the bridge of the nose, and fix it there.
5. Place the glabella support with built-in lateral adjustment on the patient’s median plane, and fix the fixing screw.
6. Allow joint support to move freely by undoing the toggle screw. While the patient is fixing the bite fork, push the bite fork adapter into the groove of the bite fork. Then screw the fixing screw of the bite fork adapter tight. Now screw the toggle screw tight. Warning: In order to ensure that the registration can be put into the transfer stand without any problems later, the toggle screw of the joint support must be pointing to the right.
7-8. Once the impression has been created, undo the bridge screw of the nose bridge and the fixing screws of the face-bow.
9. After undoing the fixing screws, pull the face-bow and registration gently apart and take carefully off the patient’s face.
10. Impression with transfer stand and transfer table: Remove the joint support from the face-bow and place it into the transfer stand. Screw the joint support’s fixing screw tightly. Apply a small quantity of articulation plaster to the plate of the transfer table. Place the transfer table on the transfer stand, and place it right underneath the bite fork until the bite fork has left an impression in the plaster. Now, screw the hexagonal bolt of the transfer table tight.
Tip: It is generally recommended that the registration be impressed in plaster in order to prevent subsequent unintentional manipulation of the registration.
