Orthodontics Kawana, Sunshine Coast

Orthodontic techniques fall broadly into two groups that reflect the differing views about the cause of the irregularity of the teeth.

Practitioners of Traditional Treatment hold the view that the dimensions of the jaws are largely predetermined at birth. As a result they extract teeth in crowded arches and use ‘traditional’ fixed appliances to align the teeth within the existing dimensions of the jaws, resorting to orthognathic surgery if the disproportion is severe. A second group of practitioners believe that over the last two hundred years industrial pollution, SOFT diet, use of pacifiers/baby bottles and lack of breastfeeding has caused narrowing of the upper jaw. In people living in remote areas, where industrialisation and modern life have not yet reached them yet, wide jaws and no crowding are the common finding.

This second group uses a combination of ‘Expansion’ appliances to widen narrow jaws, and ‘Functional’ appliances to reduce inter-arch differences. This approach is called ‘Dentofacial Orthopedics’ meaning ‘moving bone’ or ‘Orthotropics’ meaning ‘growth guidance’.

Dentofacial Orthopedics and Orthotropics may have greater potential for a long-term correction but are very dependent on the cooperation of the patient, which makes them unpopular with traditional orthodontists/dentists. It takes a special dentist-patient relationship to produce good patient compliance. Both groups accept that the teeth and their supporting bone are in a position of balance between the soft tissues (lips, cheeks, tongue) and are aware that adverse oral posture is likely to be associated with disruption of growth. Unfortunately, oral posture is difficult to measure, diagnose or treat.

Orthotropists go to great efforts to correct the effects of the environmental problems by means of appliances that strengthen the jaw muscles and train the patients to keep their mouths closed in the expectation that this will encourage natural forward growth of the face instead of the more subsequent downward or vertical growth. They claim that if this is achieved while the child is young, they will grow up with a good-looking face and at least 28 teeth in good alignment. Many clinicians use a mix of the two systems but there is concern that the treatment objectives may sometimes conflict.

Techniques

The balance of the face and the airway are respected at Lake View Dental  with straight teeth being a third part of the overall treatment goal. Primary (baby) teeth are not extracted to alleviate crowding and jaws are developed to accommodate the teeth. Permanent teeth are not extracted to alleviate crowding for children and adolescents and only in very rare cases for adults. Instead, space is made for the teeth. (Wisdom teeth are a separate, unrelated issue.) We believe a broad smile is more attractive, and jaw development treatment to accommodate the teeth helps keep the airway from being compromised. Traditional Headgears are NEVER used to push the upper teeth back and upper teeth are almost never too far forward relative to the rest of the face! It’s the lower jaw that is too far back making the upper teeth appear to be too far forward! Treatment for children and adolescents is done as early as possible to achieve the best result in the shortest amount of time.

Malocclusions (crooked teeth) and unfavourable facial development are caused by altered oral posture (the way the tongue, teeth, and lips are held at rest and in action). Because breathing through the mouth rather than the nose is frequently the cause of altered oral posture, we try to find the reason someone is a mouth breather and change the pattern to nose breathing. In turn, this supports proper dental and facial development and stability of the orthodontic result. Deviant swallowing is the stamp of malocclusion, and the adversary of the functional dentist, therefore there is need of Myofunctional Therapy in conjunction with the treatment as well as breathing retraining.

FAQs

Early orthodontic treatments (Phase I) usually begins at around age 7 when the child still have a number of milk teeth together with a few permanent incisors. The goal of Phase I treatment is to intercept both mild and extreme cases of orthodontic disorders early on with the goal of minimising or eradicating it. There are a number of problems that can be corrected with Phase I treatments including teeth crowding, spacing and crossbites. The benefits of Phase I treatment is that this period is when the child’s dental structure is still forming and malleable enough to be worked on.  This will minimise the need for teeth extraction or surgical interventions offering more long-lasting results.

There are a number of teeth problems that could indicate the need for braces.

The first is “buck” teeth or teeth that protrude excessively over the lower teeth. If you have a deep bite where the upper front teeth cover a large portion of the lower teeth when biting down. An underbite where to upper front teeth are behind or inside the lower front teeth. If the upper and lower front teeth don’t touch when biting together. If your teeth are crowded or overlapped, you may need braces. If the centre of the upper and lower teeth is not lined up. Finger or thumb sucking habits that continue beyond the age of 6/7 years old may cause the need for braces at a later stage. If you experience difficulty chewing and your teeth wear excessively or unevenly then braces might be a suitable option. If the lower jaw shifts to one side when biting together or if there are spaces between the teeth, then you may want to consider braces, however, there are other more subtle indications for treatment that include teeth grinding, sleep-disordered breathing, a smaller chin, mouth breathing, forward head posture and jaw clicking.

Orthodontics is about both the aesthetic as well as the functionality of teeth. Of course, it is possible to gain a more attractive smile along with reduced appearance-consciousness during critical development years. But orthodontics can also provide a better function of the teeth along with improved force distribution and wear patterns of the teeth. Self-confidence may increase along with the ability to properly clean the teeth. Orthodontics may also give better long-term health to teeth and gums while guiding permanent teeth into more favourable positions and reducing the risk of injury to protruded front teeth.
