Facial profile improvement, smile enhancement & benefits of early mixed dentition utilising Invisalign

Visiting the dentist every six months is not something anyone looks forward to, but it is one of the most important appointments to keep. At a check-up dentists do more than search for decay. Besides filling cavities and sloughing away tartar build-up, dentists also check for signs of oral cancer, gum disease, and seek problems beneath the surface through advanced technology, all while improving functionality and keeping good habits in check.

Facial profile improvement and smile enhancement with Invisalign by Dato’ Dr. How Kim Chuan

In this issue I would like to discuss facial profile improvements after Invisalign correction of Class 3 underbites. As you can see from the images, this patient suffered a protruding chin and lips. In addition, we can see that she sported a flatter nose – especially when compared against the nose and chin. 

In order to treat her shapeless facial features and underbite, we retracted the lower jaw by extracting her premolars. Similarly, we expanded the upper teeth by retracting them as well. During treatment, we found that her soft tissues - including her lips - followed her teeth’s direction during retraction. As extracted spaces closed and as lips retracted, this patient enjoyed additional advantages of a sharper and more contoured jawline and nose. In professional medical practice, these sharper, more defined facial contours are known as the lip, chin and neck angle. 

In terms of her teeth, this patient’s smile mainly consisted of lower incisors. After Invisalign however, her smile mostly displayed the upper teeth. This is because Invisalign has capacities of intruding and extruding the lower and upper teeth, so that one sits comfortably behind the other. In other words, as Invisalign treatment continues, upper teeth presentation persistently improves, while lower incisor displays continually diminishes.

Ultimately, we wanted to prove that difficult cases like underbites can be corrected with Invisalign. Although most believe Invisalign simply manages mild discrepancies, Invisalign has proven to correct Class 3 malalignments and similarly augment and enhance the face’s features and profiles as well. 
Benefits of early mixed dentition utilising Invisalign by Dato’ Dr. How Kim Chuan

Many parents are taught to believe that dental crowding among children can only be corrected after all baby teeth have exfoliated, and once all permanent teeth have erupted. I want to challenge these beliefs, as such teachings don’t do patients any justice. Furthermore, and based on the images, if this patient didn’t undergo Invisalign Teen interception and early intervention, outcomes could have been dire, requiring dental extraction at best, or invasive orthognathic surgery at worst. 

The benefit of Invisalign Teen is early intervention during the child’s developmental stages. With early intervention, Invisalign Teen has capacities of stimulating jaw growth in order for permanent teeth to erupt properly. Through optimal growth modification, we’re able to eliminate unnecessary surgical requirements, including dental extraction and potential jaw surgery. In short, by introducing early orthodontic care with Invisalign Teen, we’re advocating superior growth and smiles for years to come.
