People worldwide have undergone clear aligner treatment, and it is easy to understand why. The trays are virtually invisible, removable for meals, and made from smooth plastic that sits comfortably against your teeth and gums. For patients in Brisbane and beyond, they represent a modern, discreet way to address functional dental concerns without the brackets and wires of traditional braces.
This guide covers everything you need to know: how custom aligners are made, what conditions they treat, who is a suitable candidate, and what daily life with aligners actually looks like.
I am Dr Nick, a Specialist Orthodontist with over 30 years of experience and a Platinum Elite Invisalign provider at NK Orthodontist in Chermside and Spring Hill, Brisbane, where I have overseen custom clear aligner treatment for thousands of patients across both practice locations. Every piece of information in this guide reflects the clinical standards and patient care principles I apply in practice every day.
What Are Custom Clear Aligners and How Do They Work?
Custom clear aligners are a series of transparent, medical-grade plastic trays designed to move teeth a fraction of a millimetre at a time. These appliances utilise proprietary materials like SmartTrack or advanced BPA-free polymers to apply consistent, gentle force to specific teeth. Unlike traditional appliances, they do not rely on metal brackets or wires to achieve results.
The Mechanics of Tooth Movement
The process of moving teeth with aligners is highly engineered and relies on several key clinical factors:
- Incremental Pressure: Each tray in the series is slightly different, pushing teeth toward the planned position.
- Attachment Points: Small, tooth-coloured composite bumps may be placed on teeth to help the aligner grip and rotate them effectively.
- Sequential Wear: Patients switch to a new set of trays every one to two weeks as directed by their specialist orthodontist.
- Bone Remodelling: The gentle pressure triggers a biological response where the bone around the tooth root resorbs and reforms in the new location.
While Invisalign is the most recognised brand, we also offer Spark aligners, which utilise similar advanced technology. Both systems provide a sophisticated alternative to Braces for those seeking a less visible treatment option.
Determining Candidacy for Custom Clear Aligner Treatment
Clear aligners are highly effective for a wide range of orthodontic issues, though suitability depends on the complexity of the malocclusion and patient compliance. Specialist orthodontists evaluate the health of your gums, teeth, and jawbone before recommending a specific appliance. We believe an In-Person Consultation is essential to determine if this technology is right for your specific needs.
Common Functional Issues Addressed
Modern aligner technology can address several functional dental concerns:
- Crowding: This occurs when there is insufficient space in the jaw for all teeth to fit normally, leading to overlapping.
- Spacing Gaps: Aligners can close extra spaces between teeth that often trap food and lead to gum irritation.
- Overbite: This is a condition where the upper front teeth overlap significantly with the lower front teeth.
- Underbite: This occurs when the lower front teeth rest in front of the upper front teeth.
- Crossbite: This happens when upper teeth sit inside the lower teeth, which can lead to uneven tooth wear or jaw misalignment.
The Step-by-Step Process of Getting Custom Clear Aligners
The process begins with a comprehensive clinical assessment to ensure your oral health is prepared for orthodontic movement. Advanced digital imaging has replaced traditional putty impressions, providing a more comfortable and accurate experience for patients in our Chermside and Spring Hill clinics.
The Clinical Roadmap
- Initial Consultation: Dr Nick conducts a thorough oral assessment, reviews your dental history, and discusses your functional goals.
- Digital Scanning: An iTero scanner creates a precise 3D model of your teeth in approximately 10 to 15 minutes, reducing the need for messy moulds.
- 3D Treatment Planning: Software generates a digital model of the planned tooth movements to assist clinical planning before the aligners are manufactured.
- Fabrication: Your custom trays are produced using high-accuracy medical-grade materials for a snug, comfortable fit.
- Fitting and Attachments: You return to the clinic to receive your first sets of aligners and have any necessary tooth-coloured attachments placed.
Comparing Clear Aligners to Traditional Braces
While both options aim to align teeth and improve bite function, they offer different experiences regarding visibility, diet, and hygiene. Specialist orthodontists often recommend aligners for those with active lifestyles or professional roles that require a discreet appearance.
| Feature | Custom Clear Aligners | Traditional Braces |
|---|---|---|
| Visibility | Virtually invisible clear plastic | Visible metal or ceramic brackets |
| Removability | Removable for eating and cleaning | Fixed to the teeth 24/7 |
| Dietary Restrictions | None (trays are removed) | Avoid sticky, hard, or crunchy foods |
| Hygiene | Easy brushing and flossing | Requires specialised cleaning tools |
| Comfort | Smooth plastic, minimal irritation | Potential for wire or bracket poking |
It is important to note that while aligners offer more freedom, they require a high level of patient discipline. Braces are often more effective for complex cases involving significant vertical movements or severe rotations.
Daily Maintenance and Life with Custom Clear Aligners
Success with clear aligners relies heavily on patient discipline and maintaining a strict wear schedule. Because the trays are removable, it is the patient’s responsibility to ensure they remain in the mouth for the required duration each day.
Your Daily Care Checklist
- Wear Time: Maintain 20 to 22 hours of wear daily, removing only for meals and oral hygiene.
- Cleaning: Rinse aligners every time they are removed and clean them daily with a soft toothbrush and clear, unscented soap.
- Oral Hygiene: Brush and floss your teeth after every meal before reinserting your aligners to prevent trapping bacteria against your enamel.
- Storage: Always place aligners in their protective case when not in use to avoid loss or damage.
- Avoid Heat: Never wash aligners in hot water, as this can warp the plastic and affect the fit.

Frequently Asked Questions
How long does clear aligner treatment typically take?
Comprehensive treatment usually takes between 18 and 24 months, while minor adjustments may be completed in as little as 6 to 12 months. The exact timeframe depends on the complexity of your bite and how consistently you wear your aligners for the required 22 hours per day. Dr Nick will provide a more specific estimate during your initial consultation.
Does dental insurance cover the cost of custom aligners?
Many Australian dental insurance plans with orthodontic cover contribute toward the cost of clear aligners similarly to traditional braces. You should consult your provider to understand your specific policy limits and waiting periods before starting treatment. Our team can provide the necessary item codes to help you check your coverage.
What happens after my aligner treatment is finished?
Once the active phase of treatment is complete, you will enter the retention phase to prevent your teeth from shifting back to their original positions. Dr Nick will provide custom-fitted retainers and monitor your stability during scheduled follow-up appointments. Retention is a lifelong commitment to maintaining your oral health.
Can I eat and drink with my aligners in?
You must remove your aligners for all meals and any beverages other than plain, cool water. Eating with aligners can damage the plastic, while drinking sugary or coloured liquids can trap fluids against your teeth, increasing the risk of decay and staining.
How often do I need to visit the orthodontist during treatment?
Most patients visit our Brisbane clinics every 6 to 8 weeks. During these appointments, Dr Nick checks the progress of your tooth movement, ensures the aligners are fitting correctly, and provides your next sets of trays.
