How Invisalign Works: A Guide for Adults Considering Orthodontic Treatment in Perth

Invisalign has become one of the more widely recognised clear aligner systems available to adults in Perth who are interested in improving the alignment of their teeth without the use of fixed metal braces. Using a series of custom-fabricated, removable and transparent aligners, Invisalign applies gentle, controlled forces to progressively move the teeth toward a planned position. At Odin House Dental Surgery in Innaloo, our dentists assess each patient individually to determine whether Invisalign may be an appropriate option for their particular alignment concerns.

This article explains how Invisalign works from consultation to completion, what patients can realistically expect, and the key considerations before commencing treatment. Suitability varies between patients and can only be confirmed following a comprehensive clinical examination.

What Is Invisalign?

Invisalign is a system of custom-made, transparent thermoplastic aligners that fit snugly over the teeth. Each aligner in the series is designed using proprietary software to apply controlled forces to specific teeth, moving them incrementally toward the intended final position as the patient progresses through the series. The aligners are designed to be worn for approximately 20 to 22 hours per day and are removed for eating, drinking anything other than water, and oral hygiene.

The extent of tooth movement achievable with Invisalign depends on the complexity of the presenting case and the patient’s consistency in wearing the aligners as directed. Compliance remains one of the most significant factors influencing the outcome of Invisalign treatment, as it does with any removable aligner system.

What Can Invisalign Address?

Invisalign is generally considered for mild to moderate orthodontic concerns, including dental crowding, spacing between teeth, and certain types of overbite, underbite or crossbite. It is generally not indicated for complex skeletal discrepancies or cases requiring significant vertical tooth movement, and in some instances, traditional fixed braces or a combination of approaches may be more clinically appropriate.

The treating dentist or, where complexity warrants, a specialist orthodontist will advise on whether Invisalign is suitable for a given case. Patients should feel comfortable asking their dentist to outline all of the available orthodontic options before making a decision.

The Invisalign Treatment Process at Odin House Dental Surgery

Stage One: Initial Consultation and Assessment

The process begins with a comprehensive clinical assessment, including a dental examination, X-rays and a discussion of the patient’s concerns and goals. The dentist will assess the teeth, bite and gum health to determine whether Invisalign is clinically appropriate for the presenting alignment concern.

Stage Two: Digital Records and Treatment Planning

If Invisalign is suitable, the next step involves taking detailed clinical records, typically using a digital intraoral scanner to capture a three-dimensional model of the teeth. These records are used to develop a ClinCheck treatment plan mapping the intended sequence of tooth movements, and the software allows the dentist to review the planned movements before fabrication begins. It is important to understand that a ClinCheck simulation represents the planned treatment pathway; it is not a guarantee of the final clinical result.

Stage Three: Aligner Fabrication

Once the treatment plan is finalised, the full series of custom Invisalign aligners is fabricated. Depending on the complexity of the case, a series may involve a relatively small number of aligners or may extend to considerably more. The fabrication process typically takes a few weeks.

Stage Four: Fitting, Attachments and Commencement

At the fitting appointment, the first set of aligners is placed and the dentist checks that they seat correctly. In many cases, small tooth-coloured composite attachments are bonded to certain teeth to act as anchor points and help each aligner apply force in a specific direction. Not all cases require attachments. The patient receives full guidance on insertion, removal and care of the aligners.

Stage Five: Progressing Through Treatment

Each aligner is typically worn for one to two weeks before the patient progresses to the next in the series. Periodic check appointments allow the dentist to monitor progress, confirm that the teeth are tracking as planned, and address any issues that arise. If the teeth do not move as expected, refinement aligners may be required to complete the correction.

Stage Six: Retention

Following the active phase of treatment, retainers are essential to maintain the achieved tooth positions. Without retainers, teeth have a well-documented tendency to drift back toward their original alignment, a predictable biological response that applies to all forms of orthodontic treatment, Invisalign included. Retainer type and wear schedule are discussed with each patient before treatment commences.

Risks and Limitations of Invisalign Therapy

As with all orthodontic treatment, Invisalign carries risks. These may include root resorption, gum recession, sensitivity, the possibility that full treatment goals may not be achieved without refinements, and relapse if retainers are not worn as directed. These risks are discussed openly at the consultation stage, so that each patient can make a fully informed decision before proceeding.
