Fixed Appliances

Precision Fixed Orthodontic Appliances for a Lifetime of Confidence
Fixed orthodontic appliances are essential for correcting bite problems, guiding jaw development, and maintaining orthodontic results. Unlike removable appliances, fixed retainers are attached directly to the teeth, working continuously to ensure long-lasting alignment and oral health. At Trending Smiles, we customise every appliance with precision, often collaborating with a Dental laboratory in Sydney to ensure each device fits comfortably and performs optimally.

Fixed Retainers: Maintain Your Perfect Smile
A fixed retainer is a thin wire bonded to the back of the front teeth to keep them in their corrected positions after treatment. Fixed retainers are invisible when smiling and work continuously, requiring no daily compliance. Key Features of Fixed Retainers
  • Permanent Placement: Bonded behind the teeth for discreet, invisible support.
  • Continuous Retention: Works 24/7 to maintain alignment.
  • Long-Term Stability: Can remain in place for years with proper care.
  • Maintenance: Requires flossing with a threader or interdental brush.
Fixed retainers are often combined with removable options like Essix retainers after braces for extra protection and stability.

Habit Appliances: Breaking Habits for Better Oral Health
Habit appliances are designed to stop harmful oral habits like thumb sucking, tongue thrusting, and fingernail biting. These habits can affect jaw growth and dental alignment if not corrected early. Types of Habit Appliances
  • Thumb or Finger Crib: Blocks the thumb from pressing on the palate.
  • Tongue Crib/Rake: Prevents tongue thrusting against the teeth.
  • Removable Appliances: For milder habits, similar to retainers.
  • Bluegrass Appliance: Uses a roller to encourage proper tongue placement.
These devices work continuously and are highly effective in helping children stop harmful habits that may interfere with normal dental development.
Space Maintainers: Preserving Space for Adult Teeth
A space maintainer preserves the gap left by a prematurely-lost baby tooth, ensuring the permanent tooth can erupt in the correct position. Benefits
  • Prevents Tooth Shifting: Keeps adjacent teeth from moving into the gap.
  • Supports Proper Eruption: Guides permanent teeth into place.
  • Reduces Future Orthodontic Needs: Avoids crowding or misalignment later.
Types
  • Fixed Space Maintainers: Cemented to neighbouring teeth until the permanent tooth erupts.
  • Removable Space Maintainers: Can be removed for cleaning, similar to a retainer.
Rapid Maxillary Expanders for Upper Jaw Development
Rapid maxillary expanders are a type of palatal expansion appliance designed to provide controlled widening of the upper jaw. They may be considered when a patient has a significantly narrow upper arch, transverse discrepancy or certain types of posterior crossbite. At Trending Smiles, the treatment approach is carefully planned around the patient's growth and dental development. During active expansion, the appliance applies gradual forces to encourage the desired increase in upper arch width. When Are Rapid Maxillary Expanders Used? A rapid expansion approach may be considered for patients with:
  • Narrow upper dental arches.
  • Certain posterior crossbites.
  • Transverse discrepancies between the upper and lower arches.
  • Insufficient arch width for developing permanent teeth.
  • Specific jaw and bite relationships requiring early intervention.
The suitability of rapid maxillary expanders depends on individual anatomy and growth. An orthodontic assessment is necessary to determine whether this approach is appropriate and how the appliance should be activated.
Indirect Bonding Trays: Enhancing Precision and Efficiency
Indirect bonding trays are custom-made trays designed to position attachments with high accuracy. They help ensure precise placement while saving valuable clinical time compared to conventional methods. Benefits
  • Ensures accurate positioning of attachments.
  • Reduces chair time during appointments.
  • Enhances overall treatment efficiency and outcomes.
Herbst Appliances: Correcting Jaw Alignment
The Herbst appliance corrects severe overbites and jaw alignment issues by guiding the lower jaw forward. It is fixed to the molars using rods and tubes, allowing normal movement while working continuously. Benefits
  • Corrects severe overbites and improves jaw alignment.
  • Enhances facial profile.
  • Requires no daily compliance.
In some cases, the Herbst appliance can be used with a Twin block to optimise jaw development.
Invisible Stability: Long-Term Alignment with V-Loop Retention
A V‑loop lingual retainer is a fixed retainer with small loops allowing minor adjustments while keeping teeth in position. It is bonded behind the teeth for discreet, long-term retention. Benefits
  • Maintains alignment after orthodontic treatment.
  • Hidden and comfortable.
  • Provides continuous retention.
At Trending Smiles, we provide custom fixed orthodontic appliances tailored to individual dental and orthodontic requirements. From fixed retainers and habit appliances to palatal expanders, rapid maxillary expanders, 3D expanders, space maintainers and Herbst appliances, each solution is selected according to the patient's requirements.
Frequently Asked Questions
1. What are rapid maxillary expanders used for?
Rapid maxillary expanders widen the upper dental arch and may help address narrow arches, crossbites and certain transverse discrepancies.
2. What are Herbst appliances used for?
Herbst appliances help correct certain overbite and jaw alignment concerns by positioning the lower jaw forward during growth.
3. What is a space maintainer used for?
A space maintainer preserves the space left by a prematurely lost baby tooth and helps guide the permanent tooth into position.
4. What are fixed retainers and V-loop lingual retainers?
Fixed retainers maintain tooth alignment after treatment, while a V-loop lingual retainer provides discreet, continuous retention with added flexibility.
5. What are indirect bonding trays and habit appliances?
Indirect bonding trays improve the accuracy of bracket placement, while habit appliances help discourage habits like thumb sucking and tongue thrusting.
6. Are fixed orthodontic appliances suitable for everyone?
Not necessarily. The right appliance depends on the patient’s age, dental development, bite and individual orthodontic needs.
