Orthodontic treatment is the process of detection and correction of Malocclusion. Malocclusion is the misalignment or incorrect position of the teeth in relation to each other and to the jawbones. Its forms include crowding and overlapping of teeth, gaps in between teeth, cross-bites (underbite), deep bites, edge-bites, teeth pushed too far forward, or teeth pushed too far inwards.

Depending on your age and situation, we will tailor a specific treatment plan to correct your malocclusion. Contact us now to book for an Ortho Assessment with our dentist at our Sydney practice.

Classes (Types) of Malocclusion:







Class 1: normal bite; the upper teeth is only very slightly overlapping the lower teeth; Facial profile is usually balanced

Class 2: the upper teeth and/or upper jaw significantly overlaps the lower teeth and/or lower jaw; usually results in increase in overbite and/or overjet; Facial profile is usually convex (appears “chinless”; upper lip is far too forward from the lower lip)

Class 3: the lower teeth and/or lower jaw is significantly more advanced than the upper teeth and/or upper jaw, resulting in an underbite; Facial profile is usually concave



Here at Top Class Dental, we do not just make the teeth straight. Rather, we arrange the teeth in a way that will enhance the patient’s face. We employ minimally-invasive treatment techniques that result in much less extractions than usual, and negates the need for surgery in order to achieve pleasing aesthetic results, whilst maintaining the patient’s identity. By restoring the harmonious balance between the upper and the lower jaws, we could achieve fantastic results that tend to be stable many years after the treatment.

The Carriere Motion 3D Appliance is one of the many orthodontic appliances that we use to accomplish minimally invasive orthodontic treatment. By correcting the jaw relationship from the get-go, it effectively reduces treatment time up to 50% faster than conventional treatment.








Below are two videos that simulate Class II and Class III Correction using the appliance prior to braces/aligners.

Most orthodontic problems arise in early childhood. Some of them are genetic in nature, while some are products of lifestyle, diet, and oral habits. But unfortunately, many cases go undetected by the parents or even by the dentists in these early years.

In the past, children visit an orthodontist for treatment when they reach age 12 to 14 years since all the permanent teeth have erupted by this time. With this practice, most dentists extract a tooth to correct bite problem or teeth crowding. However, according to the American Academy of Orthodontics, all children should be brought to the dentist for proper orthodontic assessment by age 7 when the first set of permanent molars had erupted. Treating children at much earlier ages, say between 7 to 11 years, will take advantage of the child’s continuing growth and they are more compliant and receptive with treatment at this age. With interceptive treatment, fewer or even no teeth are extracted and there are better results.

When you bring your child in for his/her regular check-up here at Top Class Dental, we don’t only check the holes on their teeth, but also pay close attention to how their teeth, bite, and jaws are developing. We know and look out for those early signs of malocclusion, and we make sure that as a parent, you are well-informed if this is something that we detect in your child.

Interceptive Orthodontics is NOT having “BRACES”. It is a phased type of orthodontics which is the practice of extracting malocclusions once they are detected in an attempt to avoid adult malocclusion.









“Why does my child need Interceptive Orthodontics now when he/she will end up with braces later on anyway?” — you might ask. The answer is simple: any form of treatment from an orthodontist is performed a lot easier during the younger years than during adulthood.

Below are some of the other advantages of starting with Interceptive Orthodontics over waiting until “old enough” for braces:

  • far better results
  • take advantage of child’s growth to “guide” the facial and jaw bones to grow into correct positions
  • Corrects the “root” of the problem
  • Eliminates poor oral habits (such as thumb sucking, tongue thrusting, mouth breathing, etc.)
  • Better aesthetic results (better facial profile)
  • Reduces or eliminates the need for tooth removal
  • Even if the case will still need Braces to finish up the treatment, it is usually faster and easier.

There’s a vast array of orthodontic appliances used to intercept developing malocclusion. Contact us on 02 9744 0222 for an Ortho Assessment (including 3D X-ray Scan, 3D Intraoral Scan, Photos) to know which one applies to your child, or to know whether your child needs one in the first place.

Why do Adults need Orthodontic Treatment to treat Malocclusion?

Malocclusion, when left untreated during childhood, persist and get worse during adulthood. The consequences of uncorrected malocclusion include:

Increased susceptibility to periodontal/gum disease and tooth decay. Crooked teeth harbour and retain plaque a lot easier than teeth with a straight alignment. If left long-term, this could lead to irreversible gum/bone disease and tooth decay.

TMJ Disorder. Since our jaw joints (TMJ – Temporo Mandibular Joint) are directly affected by the way we bite, incorrect bite can trigger and sustain TMJ disorder.

Diminished Self-Confidence. When your teeth are crooked, your tendency is to hide your smile. This in turn affects your confidence which ultimately impacts your life as a whole.

If you are one of the many few who missed out on the opportunity of getting your teeth aligned while you were younger, fret not, because IT’S NOT YET TOO LATE.

You can still achieve a beautiful smile with any of the orthodontic treatment options that we offer as discussed in the next section.

They are fixed appliances bonded on the front side of your teeth, that aim to move your teeth to ideal position. There are different types of braces: Metal, Clear Braces (Ceramic/Saphhire), or self-ligating.

Metal Braces

They’re the most basic and cheapest type of braces. They are also the easiest to maintain, that’s why they’re perfect for kids/teenagers who at their age may still struggle in keeping their oral hygiene. Plus, it’s always fun to change and mix-and-match the colour of the rubber ligatures, or “O-rings” on the braces!



Clear Braces (Ceramic/Sapphire)

From the name itself, it’s virtually clear, sometimes almost invisible when you take photos with them on your teeth. Because of this aesthetic property, this is usually the bracket of choice for adults. The material is usually either Ceramic or Sapphire, and we have both of them in stock in our practice ready to go for your appointment!

These are clear plastic aligners used in sequence until the desired result is achieved. They are very aesthetic due to the absence of bonded braces on the teeth.  For more information about ClearAlign, click here.
