Orthodontic Buccal Tube

Orthodontic Buccal Tube is an important component used in fixed orthodontic appliances to connect arch wires and apply corrective force, usually bonded to the buccal surface of molars (first and second molars). Here is a detailed introduction:

1.Structure and Function Basic structure:

Tube: Hollow metal tube used to accommodate the main or auxiliary archwire.

Bottom plate: A metal base bonded to teeth, with a mesh or dot like structure on the surface to enhance bonding strength.

Additional structure: Some cheek tube designs include hooks or auxiliary tubes.

Function:Fix the arch wire, transmit corrective force to the molars, and control tooth movement. Collaborate with other accessories such as traction hooks and springs to achieve complex orthodontic goals such as closing gaps and adjusting bite.

2.Common types Classified by location:

Single tube buccal tube: with only one main arch wire tube, used for simple cases.

Double tube buccal tube: includes a main arch wire tube and an auxiliary arch wire tube.

Multi tube buccal tube: additional auxiliary tubes are added to meet complex orthodontic needs.

Classified by design: Pre formed buccal tube: standardized design, suitable for most patients.

Personalized buccal tube: customized according to the shape of the patient’s dental crown for better fit.

Classified by Material: Stainless steel: the most commonly used, with high strength and corrosion resistance.

Titanium alloy: suitable for people who are allergic to metals, with better biocompatibility.

3. Clinical application Bonding steps:

Dental surface acid etching treatment.

Apply adhesive, place cheek tube and position it.

Light cured or chemically cured resin bonding.matters needing attention: Accurate positioning is required to avoid interference with biting or arch wire sliding.

When bonding fails, it is necessary to re bond in a timely manner to prevent interruption of corrective force.
